The U.S. Federal Communications Commission (FCC) “Covered List,” originally published in 2021, identifies communications equipment and services that it says pose a threat to national security. On 28 July, the FCC added mobile, communicating robots weighing more than 2 kilograms and power inverters commonly used in solar panels to the list, meaning that new products from any foreign country in these categories are no longer eligible for import.

The move is a Department of Defense–driven expansion of scattered federal efforts to further limit U.S. exposure to potentially sensitive Chinese technology, but it may impose major changes on the robotics industry in allied countries, too.

The FCC’s announcement says:

All foreign-produced advanced robotic devices pose an unacceptable risk to the national security of the United States and to the safety and security of U.S. persons…unless the [Department of Defense determines that] a given foreign-produced advanced robotic device, or a class of such devices, does not pose such risks.

There are two important definitions here. The first is what an “advanced robotic device” is, and the second is what “unacceptable risk” means. Drones already went through their own round of this sort of regulation, so they’re exempt from this particular restriction, as are connected vehicles and medical devices. As far as the FCC is concerned, “advanced robotic devices” are mobile systems that incorporate on-board sensing and communications and have some amount of autonomy. There are a couple of loopholes, including systems weighing under 2 kilograms and any system that communicates at less than 200 kilobits per second, which opens up some creative possibilities. It’s important to note that this applies to new devices; those already certified are not restricted for sale or use.

As to the risks, the U.S. government says that foreign advanced robotic devices represent “a cybersecurity risk that threatens the security of critical infrastructure and thus the safety and security of U.S. persons.” There seem to be two main points to the justification, found in Appendix C. The first is that mobile robots are important to both the economy and the military, so the United States needs its own supply chain and industrial base rather than relying on foreign manufacturers. And second, mobile robots monitor critical infrastructure in sensitive locations, making them a security risk.

The Country That Must Not Be Named

As part of its justification for why foreign robots are a security risk, the DOD cites IEEE Spectrum’s article on a critical vulnerability in robots from Unitree, based in Hangzhou, China, along with several other news articles and reports about Chinese robotics. And despite the FCC swearing up and down that this action is “country neutral” and “not targeted at any country or countries,” U.S. national security sources told Spectrum that the perceived threat is obviously China. That’s how China feels about it, too, per a Chinese Ministry of Commerce 29 July press conference (translation of the first quote here):

On the surface, the FCC’s measures fly the banner of “non-discrimination,” but in substance they discriminate against and suppress Chinese enterprises and products…

China firmly opposes the U.S. overstretching the concept of national security and going after Chinese companies. Protectionism does not make the U.S. more competitive and will only hurt the interests of U.S. companies and consumers. China will continue to do what is necessary to firmly defend the legitimate and lawful rights and interests of Chinese companies.

It’s unclear what China is going to do about this—but how about the rest of the world? How can foreign companies that make advanced robotic devices get them cleared for FCC authorization? Among many, many other things, you’ll need to provide “a detailed, time-bound plan to establish or expand manufacturing in the United States for the advanced robotic device.”

Because China also produces a large fraction of robot components, even for robots assembled in the United States, it will have strong leverage in any related negotiations until U.S. robotics companies further diversify their supply chains.

Applicants must also submit their applications to the DOD and FCC by 1 January 2028, which is unfortunate for anyone who wants to develop an advanced robotic device after that point.

Robotics Industry Reactions

This is all very new, and reactions from the robotics community have been mixed.

Some American robotics companies may benefit in the local market from the newfound lack of competition in the commercial market. Brendan Schulman, Boston Dynamics’ vice president of policy, wrote an enthusiastic endorsement of the ban on LinkedIn: “I sense that this is just the first round in a series of policies that will define the success and growth of the industry for decades to come.” On the other hand, third-country buyers may just stick to Chinese products, as they generally have for drones and electric cars.

But not all companies expect major changes from the new regulation. American customers “need to know they can audit the technology, get support quickly, and keep the system operating without depending on a fragile overseas supply chain,” Nic Radford, the CEO of the U.S. humanoid robotics company Persona, tells IEEE Spectrum. In other words, he figures some customers wouldn’t have wanted Chinese humanoids anyway.

Philipp Frey, vice president of strategy for the Swiss quadruped company ANYbotics, agrees. He says their enterprise customers in the United States “increasingly evaluate robots on long-term reliability, cybersecurity, software capability, safety certification, serviceability, and ecosystem integration, not on hardware cost alone.”

ANYbotics also plans to apply for conditional approval of future products, Frey says. That will involve a national-security review by the DOD or the Department of Homeland Security, disclosing company beneficial ownership, supply-chain risks, and declaring a plan for establishing a significant manufacturing presence in the United States.

Gavin Kenneally, CEO of the U.S. quadruped company Ghost Robotics, is more explicit about the risks that Chinese robot strategy poses to the United States. “Active and purposeful spyware is deployed inside the U.S. on Chinese robots. Examples of predatory pricing abound. And this isn’t just a competition between U.S. and Chinese robotics companies; it’s between private U.S. companies and China’s coordinated national strategy,” Kenneally tells Spectrum. “If today’s announcement encourages stronger cybersecurity and a more level competitive environment, that’s good for customers and good for the robotics industry.”

So is an industry-wide ban the best way to guard against threats? American approaches to Chinese technology security risks have been “ad hoc and fragmented,” wrote the Brookings Institution sociologist Kyle Chan in a report published 9 July. Chan called for the Bureau of Industry and Security, part of the Department of Commerce, to centralize federal information gathering and decision-making on how to handle risky foreign devices. He also called for better public input mechanisms for these issues, and a continuous, proportionate process that tightened or relaxed targeted import restrictions in response to well-defined risks.

That would allow American industry to continue benefiting from partnerships with Chinese manufacturers in less sensitive links of the supply chain, Chan argues. Those links will evolve over time, requiring continued assessment, but without those partnerships, crude bans “could make it more difficult for American startups and researchers to develop new software and end up slowing innovation across the U.S. robotics ecosystem,” he writes.

For a while there, it seemed as though robotics as a whole was stuck in a mad rush towards building humanoid robots mostly because it was very possible (and very lucrative) to do so, even without near-term goals that were necessarily realistic. Some of the magic of those first couple of years of the humanoid explosion has stuck around, but there’s also been an industry-wide sobering leading to pointed questions about practicality and value. In other words, starting a commercial humanoid company now is a much different proposition than it would have been just a few years ago.

On 15 July, Walden Robotics emerged from stealth with US $300 million in funding at a valuation of $1.1 billion. Walden is a spinout of Toyota Research Institute (TRI), and it’s spent the last 10 or so years working on hard problems in robotics with the goal of transitioning from research to real-world applications. That seems like the amount of time and experience that it might reasonably take to develop a practical and value-driven approach to deploying general-purpose humanoid robots, and Walden has chosen an excellent starting point by skipping the legs.

“It’s ironic,” says Walden cofounder and CEO Russ Tedrake. “I thought about legs for 20 years; that’s the class I teach at MIT. There are many reasons to build a robot with legs. But the question is, what’s the addressable market? And what percentage of it is covered by a wheeled base?” It’s this focused, practical thinking that sets Walden somewhat apart from many (if not most) of the other companies in this space. Rather than developing a robot first and searching for a viable commercial use case second, Walden instead identified applications where robots can provide value now, and designed a robot that could safely and efficiently meet those needs.

Walden Robotics’ Manufacturing Focus

Tedrake is light on the details about what specific applications Walden is targeting at this point (citing confidentiality with current commercial partners). Manufacturing and logistics environments where there are a lot of relatively simple and repetitive tasks that aren’t friendly to conveyor belts and preprogrammed robot arms are a good bet. Even in these environments, however, robots still have to find a useful niche because they’re going up against human workers who are more flexible while also cheaper to employ. So the question is: How do you make an argument to a customer that a robot is actually a better solution than their existing human workers?

“You need to find applications with high utilization—where the robot is used 24 hours a day, 7 days a week,” says Tedrake. “Manufacturing is a global imperative right now, and it makes the economics work.” Economic viability is a necessary condition, but it’s not a sufficient one for Walden, or for their partnership with Toyota. People are a big part of Walden’s plan, too.

One of Walden’s major strengths is the company’s partnership with Toyota, which is not all that surprising given that Walden is a spinout from TRI, which is Toyota’s Silicon Valley–based R&D arm. “Toyota was very proud of the work we had done at TRI, and was ready to go big in this space,” says Tedrake. “Part of the excitement of having Toyota as a partner is that their culture is deeply people-first. When talking to Toyota’s leadership, I was never asked how much money this is going to make, but I was asked how it will improve the quality of life for all people.”

The robot’s chonky design allows it to meet the high-payload requirements of useful manufacturing work.Walden Robotics

In this context, at least in the short term, Walden’s approach to improving the quality of life for people is to take over those aforementioned repetitive manufacturing tasks with robots. Tedrake hopes that this will lead to workplaces where skilled craftspeople are able to do even more with their hard-earned expertise, increasing their efficiency, productivity, and happiness all at the same time—a noble goal, although there’s only so much Walden itself can do to make this happen, and not all customers will share Toyota’s priorities.

Wheeled Humanoid Robots in Factories

Many other humanoid robotics companies are also targeting these logistics and manufacturing spaces with general-purpose robots, and they’re doing so by making robots that are as humanlike as possible. The theory is that a humanoid form factor is necessary when operating in human environments. And there are certainly arguments in favor of a humanoid with legs—stairs exist, for one, and legged robots have a smaller footprint compared with ones that have wheels.

But a large wheeled base offers some significant advantages, as Tedrake points out. You’re incentivized to cram the base full of batteries, since more weight near the floor keeps the robot stable, which also solves the problem of running out of power during the middle of the workday. More importantly, a statically stable robot that moves around on a wheeled base can bypass the safety challenges that are currently keeping legged humanoids physically separated from real humans—most prominently, the fact that legged robots can fall over. “Factories already have autonomous mobile [wheeled] robots,” explains Tedrake. “They already have safety cases built around AMRs. You can piggyback on that with a wheeled base.”

Simple, rugged grippers make the robot suitable for commercial deployment.Walden Robotics

Walden’s perspective on manipulation is similar. Many humanoid companies are using five-fingered hands that are highly dexterous but also highly complex, which Tedrake believes is not a pragmatic approach in the context of commercial deployments. “There’s a question of what you need to do the tasks, but the real question is just durability,” Tedrake says. “We have been deployed in a Toyota factory, and at the end of the week, the hands take a beating, so we built hands that can take that. I have not seen a more dexterous hand that could have done the work our hand has done.”

Walden’s long-term plan is to build “general-purpose robots.” It’s not always clear what a general-purpose robot is, because (I would argue) nobody is quite sure what “general purpose” means. It’s certainly not referring to robots that can do everything; I think the closest we can get are robots that can be taught to do a useful number of different skills, which is why I prefer the term “multipurpose.” It’s a little pedantic, I know, but I think the distinction is important because it moderates expectations in the near term.

Part of where Walden’s optimism towards general purposeness comes from is TRI’s earlier research on diffusion policy, which helps robots learn new skills more quickly by leveraging previously learned skills as a foundation. “Fundamentally, multitasking is a way to get to a general-purpose robot,” Tedrake says. “I believe there is a single platform that can do a lot of tasks that are of high value for real customers. That will give us the experience we need to give birth to this deployed general-purpose capability.”

Why create robot intelligence for just one hand, when we could have it learn from many? GEN-1, our latest embodied foundation model, now supports a broad range of end effectors from 5-finger hands, to specialized tools, and everything in between. Each hand is a different sensorimotor interface by which GEN-1 experiences the physical world. Scaling pretraining across thousands of these interfaces teaches GEN-1 a universal physical common sense that transfers to new hands and new ways to grasp, push, pull, twist, and more.

And to illustrate this concept, a surprise spatula.

How does a robot learn to recognize an object it’s never encountered? In this case, a demo can be worth a thousand words. Short human demonstrations can be used to create fully automated training datasets, sidestepping the prompting limitations that hold back vision-language models. Rather than describing objects with language, the system tracks what a person touches and manipulates during a demo, follows those objects through time, and clusters detections to handle objects merging or splitting apart in the scene. This bypasses a core weakness of VLMs, which struggle to reliably detect unusual or novel objects even with repeated, carefully engineered prompts.

In this work, we present a systematic evaluation of contemporary humanoid technology for laparoscopic surgical tasks. We develop a humanoid-based laparoscopic teleoperation framework using general-purpose instruments and assess its capabilities through benchtop characterization, dry-lab user studies spanning diverse surgical experience levels, and in vivo porcine studies. Across these evaluations, we quantify technical feasibility, task performance, and clinical readiness relative to established surgical platforms. Together, our study provides an evidence-based assessment of the current capabilities and limitations of humanoids for surgical applications, highlighting both their promise and the key technical challenges that must be addressed before clinical deployment.

Quadrupedal locomotion in complex environments requires multiple motor skills, stable gait transitions, and perceptive control over a broad range of speeds. APT-RL (Action Pretrained Transformer-based Reinforcement Learning) is a unified framework for high-speed, multiskill locomotion.

In real-world experiments, KAIST HOUND traversed stairs, hurdles, stepping-stones, gaps, and fallen branches. It reached an instantaneous peak speed of 4.25 meters per second while traversing a 60-centimeter step and 6 m/s during a drop-down transition on a three-step staircase.

We saw some footage of this last week, but here’s a much better video.

Wing-propelled diving birds flap their wings to move through air and water, yet the wing morphology and kinematics that enable this behavior remain poorly understood because of the difficulty of collecting in situ data. The impact of flapping frequency, wing size, and stiffness on locomotion in—and transition between—the two media are still unknown. We compared data from diving birds against experiments using a flapping-wing robot capable of flying, swimming, plunge diving, and exiting the water. We show that frequency adaptation, flexible wings, and powerful actuation enable seamless transitions without folding wings or legs, that large wings enhance flight without substantially reducing underwater efficiency, and that tail-body distance and egress angle affect water exit. These results clarify how birds (and robots) balance multifluid locomotion constraints.

[ EPFL LIS ]

There are many words that I would never, ever use to describe a drone. Stealthy. Subtle. Whatever the opposite of obnoxious is. Much of this is because of the giant angry bee sound that drones tend to make, but it’s also the way that they look in flight: With uncannily linear movements and an even less canny ability to hover perfectly still, they tend to draw the eye as affronts to nature.

In a paper presented this week at Robotics Science and Systems 2026 in Sydney, roboticists from Northwestern University, Evanston, Ill., demonstrated a drone called Phantom Twist that is essentially invisible to humans, being an order of magnitude more difficult to see in flight than a typical quadrotor. They accomplished this with the aid of computational design, and while the resulting hardware is, I would argue, also an order of magnitude more of an affront to nature than a typical quadrotor represents, it’s pretty amazing how well it works.

Phantom Twist spins so fast, it’s practically invisible.Michael Rubenstein/Northwestern University

The trick here is easy to see, even if the drone isn’t. By spinning in flight at between 15 and 25 hertz, Phantom Twist takes advantage of humans’ decidedly mediocre visual system to turn a solid spinning object into an opaque smear. Human eyes take some amount of time (typically about 100 milliseconds) to integrate what we see before sending the full scene off to our brains for processing. Moving objects can cause problems for this system, because if the movement is fast enough, our eyes are forced to average that motion across the scene, combining it with whatever is in the background and resulting in a transparent blur. This effect is called persistence of vision. For something that spins like Phantom Twist, that motion blur comes from the drone’s rapid rotation, and it works because most of the drone is cleverly designed to be empty space.

Drones that spin in flight are nothing new—we’ve covered a bunch of them in the past, including Picolissimo and any number of samara drones inspired by the spinning flight of maple seeds. What makes Phantom Twist unique, and also very odd, is that the design was computationally optimized for low visibility.

Controlling how drones like this fly

Before we get into that, though, a quick note about how drones like this can even fly controllably, because it’s not at all obvious. With just a single motor and no control surfaces, the only possible control input is through the motor itself, and by pulsing the motor speed up or down at just the right time during each rotation, the drone can translate in any direction. Altitude control comes from changing overall motor thrust, and the drone‘s spinning nature makes it passively stable.

Carbon fiber rods connect batteries, a controller, some counterweights, and a motor and propeller. The research robot also includes optical tracking tags.Michael Rubenstein/Northwestern University

The bits that you need for this kind of drone include the motor and propeller, a couple of batteries, a controller, some counterweights (which could be replaced with more batteries or payload), 0.8-mm carbon fiber rods to tie it all together, and a connector for the handheld launcher that gets the whole thing up to speed. The actual arrangement of these components is surprisingly flexible, and that’s where the invisibility comes in.

“The design space is high dimensional,” explains Northwestern’s Michael Rubenstein. “It’s very difficult for a human to reason through all the trade-offs between the physical constraints required for stable flight and the visual appearance of the spinning drone, and I don’t think we would have easily arrived at this low-visibility design ourselves.”

The visibility (or not) of Phantom Twist is primarily driven by the extent to which different components line up with each other from the perspective of someone looking at the drone. The more components that line up with each other as the drone flies, the less background you see through the spinning drone, and the more visible the drone becomes. Because you might be looking at the drone from a number of different angles, and also because the drone has to be stable enough for controlled flight, there are a bunch of different things that need to be optimized all at once, which is why computational design is effective here.

Phantom Twist’s final design was generated using an iterative optimizer which had a goal of minimizing a metric called learned perceptual image patch similarity, or LPIPS, while making sure that the design could still physically work. LPIPS is the difference between two images: a background image, and a background image with an overlay of the simulated spinning drone. The smaller that difference is, the more invisible that design is. It’s tricky for a human to consider all of the variables at once, but Rubenstein says that the final design does make intuitive sense, because “the automated pipeline prefers placements where components don’t visually overlap as it spins, or where the components are too close to the center of rotation.”

Two iterations of Phantom Twist drones are shown with their handheld launching mechanisms. The better-optimized version [bottom row] relocates the launcher interface to remove components that are too close to the central axis, making them more visible.Michael Rubenstein/Northwestern University

Out of a starting set of around 20,000 feasible Phantom Twist configurations, the optimized design (the one that you see or don’t see in the pictures and videos) has a LPIPS score of 0.0104. A human-designed Phantom Twist is about twice as visible, with a LPIPS score of around 0.2, and a conventional quadrotor (of the same size) would be over 10 times more visible. And there’s still a bit more optimization that could be done with the electrical wiring as well as increasing the baseline transparency of the components themselves.

Phantom Twist is currently controlled using an optical tracking system, which means that it’s not yet capable of flying outside of a controlled environment. But Rubenstein has built other drones along similar principles in the past, which have successfully flown outside, and he’s optimistic about using those techniques to break Phantom Twist out of the lab. The spinning behavior might even enable some useful sensing capabilities, he says. “An interesting possibility is mounting a camera on the spinning body. As the vehicle rotates, it could capture imagery in every direction, effectively creating a 360-degree view of its surroundings that could be used for onboard navigation and control.”

As for what a drone like Phantom Twist could be used for—assuming that the sound can be mitigated somewhat (and there are potential approaches to making that happen), a stealthy microdrone could do all sorts of things with covert surveillance being the most obvious application. For his part, Rubenstein says that he’s personally excited about the potential for watching wildlife, “where a less-intrusive drone could observe animals while minimizing its impact on their natural behavior.” The elephants in particular would certainly appreciate that.

For a deeper dive into all the particulars of this project, read the paper: Computational Design of a Low-Visibility UAV Using a Human-Aligned Perceptual Metric, by Jingxian Wang, Chen Yu, David Matthews, Emma Alexander, Sam Kriegman, and Michael Rubenstein from Northwestern University, which is being presented this week at RSS 2026 in Sydney.

We’ve created GEN-1, our latest milestone in scaling robot learning. We believe it to be the first general-purpose AI model that crosses a new performance threshold: mastery of simple physical tasks. It improves average success rates to 99 percent on tasks where previous models achieve 64 percent, completes tasks roughly 3x faster than state-of-the-art, and requires only one hour of robot data for each of these results. GEN-1 unlocks commercial viability across a broad range of applications—and while it cannot solve all tasks today, it is a significant step toward our mission of creating generalist intelligence for the physical world.

NASA is considering a mission concept for an advanced, nuclear-powered rover to be deployed to the Moon’s South Pole as part of the agency’s Moon Base plans. The PROMISE (Polar Rover for Observation, Mapping, and In-Situ Exploration) mission concept relies on the Curiosity Mars rover mission’s testbed rover. Some elements of the Perseverance Mars testbed rover shown in this video could be used as well. As exact duplicates of Curiosity and Perseverance, the testbed rovers are equipped with flight-proven engineering systems capable of carrying technology as well as science instruments that would advance Moon Base efforts.

A Mars rover for the Moon? That’s some OPTIMISM right there.

Dr. Sebastian “Basti” Scherer has worked in field robotics since the first DARPA Grand Challenge in 2004. He runs the AirLab at Carnegie Mellon’s Robotics Institute and is the director of safe embodied AI at FieldAI. While much of the industry is focused on local skills like tabletop manipulation, Dr. Scherer sees the greatest value in solving dirty, dull, and dangerous tasks that require operating in uncertain environments where the robot needs to “just work.” When robots “just work,” they become less like robots and more like tools. “That’s the big challenge that we have to overcome,” he says. “And that’s the challenge that FieldAI is really primed to solve.”

Look, I really appreciate how valuable robots like ElliQ can be, and robots that do good work and offer a financial benefit are incredibly important, especially in the context of family care.

Engineers from NASA’s Jet Propulsion Laboratory are field-testing advanced capabilities for potential future Moon and Mars rovers. In the Colorado Desert near Plaster City, California, teams used a prototype rover called ERNEST (Exploration Rover for Navigating Extreme Sloped Terrain) to test software for a potential future long-range lunar mission. The software enables the rover, developed at JPL, to operate autonomously and travel extreme distances with minimal intervention from human operators.

ERNEST is a lot more capable than it may look; here’s some recent research showing the kinds of terrain it can handle:

[ Sphero ]

Thirteen years ago last August, I was camped out in NASA’s Jet Propulsion Laboratory press room in Pasadena, Calif., waiting to see whether the Curiosity rover would survive its descent and skycrane-assisted landing on the surface of Mars. It did, and it was awesome.

Since then, Curiosity (also known as Mars Science Laboratory) has traveled nearly 37 kilometers, drilled into and sampled 42 different rocks, and as of publication has snapped nearly 763,000 photos. The fact that this robot is still hard at work, getting real science done at the age of 13, is absolutely incredible—not only is Mars an actively hostile environment for robots, but the only kind of maintenance that JPL engineers can do is to send very, very careful software updates.

Nevertheless, the clever folks at JPL have managed to keep Curiosity safe, warm, mobile, and sciencing, despite well-worn wheels and less and less power every day. One of those folks is Alexandra Holloway, the assistant team chief for engineering operations for Curiosity, who spoke to IEEE Spectrum about keeping Curiosity roving, what its future looks like, and how JPL has used that experience to make rovers like Perseverance even more capable.

How astonished should we be that after 13 years on Mars, Curiosity is not only still doing science, but actually getting more capable?

Alexandra Holloway is the assistant team chief for engineering operations on the Curiosity Mars rover at the Jet Propulsion Laboratory.Alexandra Holloway

Alexandra Holloway: I’m astonished! The longevity comes from a lot of ongoing work. It’s not just that Curiosity was built robustly; it’s also because we’re continuously putting in effort to ensure it can continue to have that lifespan. I think about all the different kinds of embedded systems there are, from cars to refrigerators, and none of them have the kind of longevity that we have with the rover. It’s mind-boggling, and it’s inspiring.

Is the Perseverance rover, which is nine years younger than Curiosity, significantly different in terms of its hardware and software?

Holloway: In terms of hardware, the rovers are actually very similar. Both use a RAD 750 processor and have the same amount of memory. However, Perseverance has an extra processor specifically for visual odometry, which allows it to drive autonomously. This difference reflects their primary mission designs: Perseverance was designed for driving long distances, while Curiosity is a mission focused on sampling as it goes. So Perseverance’s onboard scheduling capabilities are there to optimize its driving. In fact, just last year, Perseverance surpassed Curiosity’s driving distance after only about three years on Mars.

Curiosity Rover Memory and Software Fixes

Do you have some examples of significant tweaks the team has made to keep Curiosity roving?

Holloway: One of my favorite examples comes from a processor anomaly that happened on Sol 2172 [Ed. note: “Sol” is the term for a Martian day—about 24 hours and 40 minutes]. Curiosity has two computers, A and B. We landed on A, swapped to B due to a NAND memory anomaly early on (Sol 200). For years, we were chugging along on B, until one day there was a problem—B booted up, but it couldn’t mount its drive partition. We’d never seen this before. To preserve B’s data, we swapped back to A, which we hadn’t trusted in two thousand Sols. A also had a degraded memory, with only two gigabytes of usable storage space instead of four. We painstakingly transferred data from B over to A and then down to Earth, and eventually we ran out of stuff we wanted to transfer, which was really good, because A then started acting funny in the same way it did on Sol 200. It was acting like its memory was coming unsoldered. That’s bad.

We quickly swapped back to B, formatted it, and got it working again. The problem then became that we couldn’t trust A’s memory at all, but we needed a second computer as a “lifeboat” for diagnostics and transfers if B failed again. We realized we had one other place of memory: where we keep our flight software. We have four copies of the flight software (two current versions and two older versions) in different banks of very small amounts of memory, just 32 megabytes each. What if we just jettisoned the old flight software copies and used that 64-megabyte NOR memory as our file system for computer A?

So that’s what we did. It was so elegant! Computer A is operating with less than 1 percent of its original memory, but we can run a mission on it. A small mission, but we haven’t had to jettison any core capabilities. We can still drive, we can manage data, we can even theoretically do science. Everything works fine, just much slower and much smaller. That flight software release was even called “R-Hope“ because we hoped it would work.

What are the constraints on Curiosity’s lifespan?

Holloway: Our biggest hardware challenge is wheel wear. It looks like we’re driving on this sandy terrain with some rocks in it, and our intuition said that we could just drive over these rocks and they’d get pushed down into the sand and it would be no big deal. But what we ended up seeing was that those little rocks are actually the tips of giant boulders buried in the sand, and they’re razor sharp. Our wheels were getting ripped apart driving over them, especially our front wheels, so we started driving backwards.

We also monitor consumables. We consider the number of times we move our actuators. That’s a consumable. Curiosity hasn’t taken a selfie in a while, and one of the reasons is that it’s really hard on the joint actuators. Our onboard memory is a consumable, but surprisingly we’re not anywhere near our life cycle for memory. Our biggest consumable is power; we have an RTG, a nuclear power source, which decreases its output as it ages.

Newer missions are flying Snapdragon [processors], but Curiosity’s RAD 750 is a power hog. One of the things that we’ve rolled out that’s going really well is a way of reducing the amount of time we spend with the computer powered on, by harvesting time when we finish activities early and going to sleep, which lets us turn off the computers and some of the heating. Another thing we’re looking at is doing stuff in parallel when we’re on, like being able to drive or use the arm while communicating with an orbiter.

So power is decreasing, and that’s causing us to do all this parallelism work and become more efficient and nuanced in the way we operate. But we are not having any degraded science output at this time. Our wheels are still going, our arm is still okay for now, knock on wood. I would say maybe the bottleneck is budget.

Curiosity Rover’s Impact on Future Mars Exploration

What have you learned from Curiosity that will improve future missions?

Holloway: As an embedded flight software person, I think about how we can change, add, or modify software capabilities during the mission. There’s definitely a sweet spot for loading and patching flight software—some of these concepts were pioneered on Spirit and Opportunity and then inherited by Curiosity and Perseverance, making it easier to understand and change the software.

Some of the things that I wish we had now on [the Mars Science Laboratory] include a better understanding of where our power is going. I want to see how much power each component is drawing every minute, so that we could architect a software system that could balance loads better. We have some of this information that was built in by the engineers who designed the rover, but as an operator, I want something slightly different. So if I were building a mission, I would have those discussions earlier and get operators into the room to say, “what do you want your data products to look like?”

The key takeaway for designing future missions is to talk to all your users early in the design process. It needs to happen upfront.

What does Curiosity’s long-term future look like?

Holloway: That’s a conversation that happens, and it’s a really delicate one. We have a lot of science instruments, and a lot of them have to do with contact science and sampling and rely on the arm. If we lose the arm, what science can we still do? Well, we have a lot of remote sensors too, like cameras, environmental sensors, and radiation sensors. All of these things are important for the future of space exploration and humans on Mars.

From a power perspective, our RTG is projected to start degrading science output in the sixth extended mission, but we’re going to be fine through 2035 and potentially even beyond that. So we have a long and exciting future ahead of us. We need to figure out the best way of operating within our constraints, but we’re still kicking.

The longevity here is impressive, but the obvious question here is why the heck you’d ever do this task with a bipedal humanoid robot. It also doesn’t seem to have any error recovery, which is obviously fixable, but highlights the fact that real humans are versatile and humanoid robots are not.

Just months after its debut, Atlas is proving why it is the world’s most capable and dynamic humanoid robot, ready for real work. Lifting a mini-fridge is a feat of strength, but the true breakthrough is in the underlying reinforcement learning and controls systems. The robot is learning to navigate real world adaptability: handling heavy objects by bracing and accounting for the mass and inertia; using whole-body control, not just hands to maneuver; and demonstrating superhuman range of motion and balance. This marks a critical shift in robotics where humanoids move beyond the lab and into dynamic industrial settings.

Watching Atlas move a fridge may be less impressive than whatever the heck it does at 4:10.

Hummingbirds are impressive flyers, and advancements in high-speed photography, instrumentation, and measurement techniques have revealed much about their aerodynamics, flight behaviors, and wing and body kinematics. However, comparatively less is known about their natural flight dynamics, which is the relationship among a bird’s flight velocities, the control actions of its wings, and the acceleration of the bird in flight. To investigate this, at the Advanced Vertical Flight Laboratory we have designed, built, and flight tested a biomimetic robotic hummingbird on which is implemented the same techniques for flight control as observed in hummingbirds.

One of the biggest challenges in robotics right now isn’t the hardware. It’s data.

The human feels through the linkages what the robot will feel through its actuators.

Many roboticists (and at least one robotics journalist) have been seduced by the dream of a robot butler. And the rampant popularity of videos showing humanoid robots doing household tasks in improbably clean kitchens and unrealistically tidy bedrooms suggests that we’re not the only ones interested in a robot that can do our chores. But for all kinds of reasons, legged humanoids are not yet ready for industrial or commercial applications at scale, and home applications (if people even want them), I would argue, are even farther away. Even so, ludicrously well-funded humanoid robotics companies are now ramping production while explicitly promising that their robots will be doing ‘housework.’

So what about that robot butler dream, then? It still exists! All you have to do is forget about legs, arms, hands, faces, and focus on what really matters: mobility and manipulation. This is what Hello Robot’s Stretch robot is unapologetically all about, and the newest version being announced today, Stretch 4, is closer than ever to a robot that could safely do practical work in the home at an accessible cost.

Hello Robot says Stretch 4 is “built for the real world.”Hello Robot

“With Stretch 4, we wanted to make the transition from a research platform to something that is truly deployable,” explains Aaron Edsinger, Hello Robot co-founder and CEO. This version, while ready for research and enterprise customers now, is designed for pilot deployments to help Hello Robot understand how to scale in the home. “This has been our most difficult design process,” adds co-founder and CTO Charlie Kemp. “We had a lot of fear of ‘second-system syndrome,’ where you add all the features you didn’t get to initially and end up with a monstrosity. But since we founded the company on making simple, minimalist robots, every time we added complexity it was an emotional challenge. Navigating that fear resulted in a nice compromise that sits in a great spot, rather than being a maximalist humanoid.”

Stretch 4 Upgrades

The biggest change from the previous version of Stretch is the addition of an omnidirectional base, meaning that the robot can translate in any direction without having to turn first. This makes it much easier to control (especially for novice users), but omnidirectional bases are significantly more complicated to design and build. What ultimately made it possible for Stretch were new types of omnidirectional wheels developed for powered wheelchairs, along with a solid six months of focused development by Hello Robot.

A redesigned sensorized head gives Stretch more options for teleoperation and autonomy.Hello Robot

Stretch 4 also ditches the cute little pan-tilt head for a more complex sensor suite with a much wider field of view. “We started out wanting to use lots of cheap cameras to keep costs low, like Tesla does,” Edsinger tells us. “But we ended up with an approach closer to Waymo’s: the richer and more reliable your data, the safer and more intelligent the robot can be.” There are a pair of hemispherical lidars, Luxonis cameras for vision and navigation, and a wrist-mounted depth camera for manipulation. The robot’s primary system runs on an Intel NUC 15, plus an Nvidia Jetson Orin NX for researchers to play with for visual processing or AI.

Philosophy on Autonomy

Hello Robot’s general philosophy on autonomy is to have a human in the loop, but that can take many different forms ranging from direct control to purely supervisory control. The robot will ship with a baseline of autonomous capabilities that include mapping, navigation, and self-charging, along with demo-ready features like autonomous grasping. But unlike most other robotics companies, Hello Robot isn’t looking to use their hardware to collect a stupendous amount of data in the concerningly vague hope that commercially viable autonomy will follow.

“Stretch has huge advantages in safety, cost, and capability,” Kemp says. “I’d much rather be the platform that foundation model developers target.” Edsinger agrees: “We do want to partner with foundation model companies to explore things like dexterous in-home manipulation, but we aren’t the ones to build those foundation models.”

In-Home Pilots

While earlier versions of Stretch were primarily for research, Kemp tells us that Stretch 4 has been explicitly designed to be piloted in the homes of people with severe mobility impairments. Hello Robot will be happy to sell you one (or lots, I’m guessing) for commercial or industrial applications, but the broader goal with Stretch 4 is to use remote testing and in-home evaluations to work towards a robot that’s useful and reliable enough that it can provide consistent daily value for disabled users.

A holonomic base and an extendable arm make for a capable robot without the complexity.Hello Robot

Part of why I’m optimistic about Stretch finding near-term success in this role is precisely because it’s not a humanoid. One of the primary arguments for humanoids is that they’re worth pursuing because they can better operate in environments designed for humans, where legs and five-fingered hands are tangible advantages. But those very same environments often exclude an entire subset of humanity—a subset of humanity that we will all likely join at some point, because the best that any of us can ever say is that we are not disabled yet.

Why Not Humanoids?

A key partner for Hello Robot throughout the Stretch development process has been Henry Evans. Evans is paralyzed and cannot speak, although he can use a computer (for controlling robots, among other things) and type at about 15 words per minute. I spoke with Evans about his thoughts on the idea of a humanoid assistive robot, compared to a robot like Stretch. “The question is: What benefit does a bipedal robot offer to a person who can’t walk?” Evans asks. “Their entire environment has been modified to accommodate wheeled conveyances. Automobiles don’t have legs, and neither should home robots. Wheels are cheap, stable, precise, require very few controls, and don’t have to be invented.”

Henry Evans has been testing a Stretch 4 as a home assistive robot.Hello Robot

Evans also points out that humanoids can require the simultaneous control of dozens of degrees of freedom. “A paralyzed person who can’t talk (like yours truly) can control maybe one or two joints at a time with today’s control mechanisms, if they are lucky.” Evans believes that AI, along with Brain Computer Interfaces (BCIs), show promise for dramatically increasing what he can do when it comes to motion. “Remember, though, a paralyzed person has no movements to mimic, so until a perfectly tuned BCI gets here and facilitates a true humanoid body surrogate, I don’t think it will work. And even then, I don’t see the advantage of legs for assistive care robots. I am willing to be proven wrong, though, and will test-drive almost anything once, so bring it on!”

Kemp and Edsinger, who have many decades of humanoid experience between them, feel similarly. “There are applications where the human form is fundamental,” Kemp says. “But for many applications, the value of the human form is unclear or even problematic. Jumping to the conclusion that robots must be humanoid means missing opportunities to take advantage of the structured indoor environments that we’ve already created.”

Georgena Moran and her sisters tested Stretch 4 at the California Academy of Sciences Museum, allowing her to interact with the exhibits from home.Hello Robot

And of course there’s the question of safety, which Evans brings up. “My caregivers and I have been testing robots in my home to assist us for about 15 years, and the very first concerns are: Where is the emergency stop, and how do you activate it? It gets used surprisingly often. The thing is, when a wheeled robot gets emergency stopped, it freezes in place. When a bipedal robot gets run-stopped, it collapses on anything under it, including the patient.” Kemp agrees. “The safety aspect of humanoids in a home freaks me out. I don’t know how someone can confidently think about safety with a humanoid in a home.”

Robots for Sale

However you feel about humanoids, here’s one more reason why Stretch feels like a much more realistic solution for in-home assistive robots right now: You can actually buy one, and at US $29,950, it’s very affordable, as mobile manipulators go. Edsinger and Kemp are planning to leverage in-home Stretch 4 pilot deployments to make the next version of Stretch the one that can be commercially sold for home assistance. At the rate that Hello Robot has been releasing new hardware, that could easily be within the next year or so—and my guess is that Stretch 5 is very likely to be the first practical, affordable assistive robot for home use. It may not look like Rosie, but it promises to be safe, and it works.

Two years ago, Colin Angle stepped down as CEO of iRobot, the company that he cofounded and the most successful home robot company the world has ever seen. Angle almost immediately founded a stealthy new “physical AI” company called Familiar Machines & Magic (FM&M), which in short order managed to attract a combination of exceptionally talented robotics folks, including Morgan Pope from Disney Research, which got us very curious.

Today, Familiar Machines & Magic is announcing its first robot, a “physically embodied AI system designed to perceive, adapt, and interact with people in ways that feel natural and consistent,” the press release says. This robot is not a toy, and it’s not specifically for kids. Rather, it’s for adults to purchase for themselves and their families. It will get to know you, seek you out for attention, and actively help you positively pursue an idealized routine in your life.

Intended for adults, Familiar is pet-like in that it will seek you out for attention.Familiar Machines & Magic

Here are the (limited) technical details from the press release:

The first Familiar is a quadruped, specifically designed for human-robot interaction, with 23 degrees of freedom enabling both lifelike movement and expressive behaviors. The Familiar is covered with a custom touch-sensitive coat, a vision system, and a microphone array and audio system, to support rich interactions. Its onboard edge AI stack is powered by a custom small multimodal model optimized for social reasoning, combining vision, audio, language, and memory to create socially responsive behaviors in real time.

FM&M CEO and cofounder Colin Angle tells us that this first prototype Familiar is designed to look like a sort of highly abstracted bear. It’s very deliberately nothing like a dog or a cat, following the successful strategy of other social robots like Paro and Pleo—if you can’t connect the form factor to an animal that you have direct experience with, you won’t bring expectations to your interactions with the robot.

What Does it Do?

“Our goal is to position this as a robot familiar that lives with you and helps reinforce healthy routines,” Angle says. He explains that thinking of a Familiar like a pet is a strong analogy, but pet-like also undersells what the robot can do. The Familiar behaves a little more like a service animal, in the narrow sense of being able to recognize activities and intervene to motivate you to do more or less of them, as the case may be. One easy example is screen time—the Familiar can note how much time you spend on your phone, and if it’s too much, it can actively try to engage you in other activities, including taking it for a walk outside. “The idea,” says Angle, “is that you can have a bit of technology in your home which is hyperloyal to you, gets to know you, helps you figure out an idealized routine, and then plays a positive role.”

Spending too much time on your phone? Familiar can help with that.Familiar Machines & Magic

Cramming this amount of intelligence into a robot that you can take for a walk outside (at regular human walking pace) is extremely ambitious. I asked FM&M’s creative director Morgan Pope what made him feel that a robot like a Familiar was possible, with enough confidence that he was willing to leave Disney Research to join the startup. “Two recent advancements made it feel tractable,” Pope says. “First, seeing Disney’s bipedal robots walk flexibly over various terrain using reinforcement learning proved you can execute dynamic motion without needing perfect, zero-backlash actuators or crazy expensive hardware. And second, while I am often skeptical of generative AI hype, it is a perfect fit here because it excels at creating the plausible assumption of intelligence, which helps the character feel coherent and lifelike.”

The Challenge of Social Home Robots

As a social home robot, the Familiar will have quite a lot of work to do to single-pawedly reestablish a category that burned itself out between 2012 and 2019. A series of high-profile and very-well-funded startups including Anki, Mayfield, and Jibo were not able to sustain social home robots as a business, primarily because of a struggle with longer-term engagement. It’s not enough for a robot to be cute and charming in the short term; it has to continue enthralling its users or at least providing value after the initial novelty has worn off. In other words, a flashy demo is arguably counterproductive, which is a real problem, since robots excel at flashy demos.

Part of the value of Familiar is that it will help you establish healthy routines.Familiar Machines & Magic

“It’s about creating the right expectation and delivering on that expectation,” says Angle. “Familiars live in your world and play by your rules, and if you don’t find yourself hanging out with it, petting it, and engaging with it, then we haven’t succeeded.”

In what is very much not a coincidence, the term familiar really is the best way of thinking about this robot—a sort of vaguely magical nonhuman entity that has some amount of independence but whose existence and motivation are fundamentally tied to its human. “This isn’t trying to be a replacement for a real friend,” Angle explains. “It’s artificial life that lives in your world, has its own personality and goals, and has a special link to its guardian where it wants attention and wants its guardian to be active.”

Creating Long-Term Value

This philosophy is a key differentiator for FM&M. A Familiar is more than a companion; it has long-term objectives that it’s trying to fulfill to improve your life in a targeted way, says Angle. It’ll attempt to connect with you socially to encourage you to spend time with it in service of those goals, but the goals are the end, er, goals, rather than just the social connection itself, which was the primary draw of the previous generation of social robots. “Within a few days of bringing your Familiar home,” Angle tells us, “it’s figured out what its role in your life is. It’s trying to reinforce a healthy routine, whether that be summoning people to dinner or cuddling up while you watch TV, or greeting you when you get home. And then the way you sustain that relationship is by having it evolve, with both characters playing an active role—you’re also helping it with the things required to keep a robot operating.”

Human-Familiar Interaction

The temptation to leverage recent advances in AI to make a robot like a Familiar talk, especially in the context of regularly interacting with humans in pursuit of specific goals, must have been overwhelming. But to its credit, FM&M managed to resist. “I don’t believe that the technology exists today for AI to talk to humans in a safe, responsible fashion,” Angle explains. Consequently, a Familiar does not currently speak, although it does make sounds, and has plenty of other ways of communicating. “Through careful design, you’d be amazed what you can powerfully convey using a tail, wiggly ears, blinking eyes, and a brow that can be happy, sad, angry, or annoyed,” Angle says. This will likely resonate strongly with dog owners, somewhat less strongly with cat owners, and only very slightly with reptile owners like me.

Familiar is capable enough to keep up with you on walks outdoors.Familiar Machines & Magic

Going the other direction is more complicated. Those same recent advances in AI mean that a Familiar can very likely understand everything you say and obey you perfectly, if it chose to. But doing so would break the illusion that the robot has its own desires and goals and personality, so FM&M had to be careful. “The way we’ve trained it from an AI perspective is really cool,” Angle explains. “We’re using a tableau of speech and vision inputs presented to a small multimodal model trained on stories, and for a given tableau of inputs, it goes through a generative process to decide at a high level what it is going to do. That decision is handed to a behavior engine which builds out those behavior trees into goals and drives a reinforcement learning unified motion model. There is nothing fully deterministic about your Familiar’s behavior; it truly tries to live its life with a variety of personality-driven emotions.”

Safety at Home

A Familiar is not big, as robots go, but it’s not exactly small, either. And as something with legs, there’s always a concern about what happens if it falls over. “Its low center of gravity helps immensely,” says Pope. “If we pull power, it collapses downward safely rather than tipping over. Furthermore, it is wrapped in soft rubber, fur, and padding, so even if a leg impacts you, it won’t have a lot of force behind it.” Interestingly, FM&M is also leveraging the “character experience” to mitigate risks to both robot and user. “We can use emotions to communicate hazards effectively,” explains Pope. “For example, if someone carries it somewhere high or puts it near an open flame, the Familiar can act visibly scared to directly communicate that it doesn’t like the situation.”

While not a toy or specifically intended for children, Familiar can provide gentle, warm attention to your family.Familiar Machines & Magic

Besides physical safety, social robots must also consider emotional safety. The better job you do emotionally connecting with people, the more responsibility you have to make sure that those connections are positive. “We take this very seriously,” Pope tells us. “We must follow a ‘do no harm’ philosophy, ensuring we don’t trigger unhealthy dependency or monopolize people’s attention the way a phone does. We are designing carefully to ensure the overall impact remains positive and never crosses the line into harm.” Additionally, the Familiar’s AI runs onboard the robot, and the robot does not stream private data to the cloud. It will, in fact, run just fine if you disconnect it from the internet entirely, although you’ll lose access to any new features that come out.

Managing Expectations

Alongside the many engineering and human-robot interaction (HRI) challenges that FM&M is having to manage is one other challenge that, in the near term, sounds rather dull but may be the most challenging: marketing. The company obviously has to promote this robot, but there’s a real danger (which has had dire consequences for many robotics companies in the past) of selling an idea of what the robot could be rather than the reality of what the robot actually is.

From my conversations with Pope, FM&M seems to understand that robots have always been the most successful when the experience or task is incidental to the robot itself—in other words, what’s most compelling is what the robot will do, rather than the fact that it’s a robot. “The best way to understand a Familiar is that we are not building a robot; we are building a relationship,” Pope explains.

Whether in the context of locomotion or relationships, we can be absolutely certain that a robot of this level of sophistication is not going to do what it’s supposed to every single time. Fortunately, the folks at FM&M have been building robots for long enough that they’re prepared for this. “We’ve explicitly tried to design it to motivate forgiveness,” Angle tells us. “This is not a precise robotic entity in its motion or dexterity. It’s supposed to be imperfect, but it’s going to get some of it right. By actively working to manage expectations to a place we can achieve, we want consumers to appreciate what it can do.”

What customers expect, what they appreciate, and how much forgiveness they’re willing to bestow is for better or worse highly dependent on how much a Familiar will cost. “For the cost of ownership of something like a pet, you’re getting something that can help you live a healthier life, feel attended to, and provide social benefit,” Angle says. This could mean many things, depending on the pet, but one source puts the low end of the monthly cost for a cat at around $65 per month, with a dog somewhat more expensive at closer to $100 per month. FM&M’s press release stresses that today’s announcement ‘is not a commercial product launch,’ and specific pricing and a timeline will come later.

A Future Platform

While it’s much too early for us to be speculating about what the future might hold for FM&M’s robots, Angle is of course already thinking about other places where Familiars might be at home. “This first robot is meant to be a platform with general appeal and an opportunity to specialize into things like elder care and parental support,” Angle says. “From the ground up we are designing machines focused on human connection, and the underlying technology can further generalize into other form factors.”

This will require the Familiar to find success, and it’s important to reiterate how much of a challenge this will be. A legged robot, designed for human interaction, in the home—everything about what FM&M is doing is hard. Because of his experience launching and leading iRobot, Angle is one of the very few people with the experience to really understand this, but his excitement and optimism about the Familiar is undiminished. “Do we know exactly how it’s going to land?
