The flashy company, which recently completed a blockbuster IPO, appears to be leading the pack of humanoid robot makers.
Increasingly, companies are building humanoid robots that perform impressive athletic feats to mark the field’s progress. Now, Chinese robotics company Unitree says its new “Superman” robot can run 12.66 meters per second, faster than Usain Bolt’s top recorded speed.
Getting a humanoid robot to run at all requires split-second control and has been a significant engineering challenge occupying roboticists for decades. That’s why sprinting, as well as jumping, have become popular targets for robotics companies keen to demonstrate their technology’s prowess.
Unitree’s latest demonstration pushes the boundaries by not only outrunning the fastest human ever, but also jumping around 6 feet 7 inches into the air from a standing start, a full foot more than the human record.
“This new machine has only been in development for a little over three months, with significant room for further improvement in the coming months,” Unitree said in an X post that accompanied a video of the accomplishments.
The records have not been externally verified, and the sprinting speed was a peak reading taken over a shorter stretch rather than a full 100 meters like Bolt’s record. The robot’s legs are also only 2 feet 9 inches long, according to Unitree, which results in an ungainly, arm-waving gait while running.
The effort is nonetheless impressive and adds to Unitree’s growing reputation as the company leading the pack of humanoid robot developers. And the timing of the announcement was no accident, coming just days before Unitree’s stock market debut and shortly before the World Humanoid Robot Games, which opened on August 22.
The company’s Shanghai IPO was a blockbuster, recording an initial 629 percent gain on the company’s first day of trading. It was briefly valued at around $66 billion before closing at a more modest $51 billion. However, some analysts have cautioned the excitement around the company’s technology may be getting ahead of market realities.
“The IPO is expensive, and the investment risk is already quite high,” Wang Zhuo, partner of Shanghai Zhuozhu Investment Management, told Reuters. “Unitree generates much of its sales from research and demonstrations, but wider application is still far away.”
But the company holds a dominant grip on the emerging humanoid market that may justify some of the hype. Chinese firms control roughly 90 percent of the global humanoid robot market, with Unitree alone shipping 5,500 of the 13,000 to 18,000 humanoids sold worldwide in 2025, the most of any manufacturer. In contrast, US humanoid champions Figure AI, Agility Robotics, and Tesla each shipped around 150 units.
China’s success is down to “a combination of policy support, public investment, mature supply chain, and advancements made in AI software and hardware,” Lian Jye Su, a tech analyst at consultancy firm Omdia, told Rest of World.
This is leading to an increasingly combative response from the US. On July 29 the Federal Communications Commission banned new imports of foreign-made humanoid and quadruped robots. The move was framed as a matter of national security, though it has also been seen as an attempt to give domestic developers a leg up.
Beijing predictably objected, with foreign ministry spokesperson Mao Ning telling a press conference that “protectionism does not make the US more competitive, and it will only hurt the interests of US companies and consumers.”
Given the rapid progress made by companies like Unitree, it seems likely it’s going to take more than trade barriers for the US to catch up. In the meantime, we might see more human athletic records fall to China’s leading humanoid developers.
The robot removed a pig’s gallbladder with standard surgical tools in an ordinary operating room.
Watchers held their breath as the robot made its first incision. Hovering over its patient, an anesthetized pig, with a robotic assistant standing nearby, it navigated to the gallbladder and gently removed it.
The operation marked the debut of humanoid robots in a standard surgical setting. The robot, named Surgie, wasn’t autonomous—it was controlled by an expert surgeon—but the study is a step toward using humanoid robots as collaborators in minimally invasive surgery.
“Remotely operated and autonomous humanoid robots have real potential for amplifying access to critical surgeries to which patients would otherwise not have access,” said study author Michael Yip at UC San Diego.
The study included two successful surgeries. Human surgeons remained on standby for emergencies, but the teleoperated robot completed the task with only minimal intervention.
Feedback from surgeons operating Surgie was positive. They reported less physical strain and frustration, along with better overall performance. But they also pointed to practical problems like intermittent overheating and the need to frequently reposition the robot.
Despite a long road ahead, humanoid robots “have a viable future,” said Yip. “You can imagine these robots being deployed in remote communities where staffing is challenging, or in austere environments like search and rescue scenarios where a massive deployment of field medicine is needed in a short period of time.”
Smooth Operator
Robots have assisted surgeons for years. With a human surgeon at the helm, they excel at delicate procedures requiring precision and dexterity. They’re especially well-equipped for laparoscopic surgery, a minimally invasive technique that uses tiny incisions to reduce pain, speed recovery, and lower the risk of infection.
Despite the promise, surgeons face tradeoffs when they use surgical robots. The robots are highly specialized and often require operating rooms to be redesigned to accommodate them.
A major reason for this is the way they’re built. Intuitive Surgical’s Da Vinci system, for example, uses a robot with multiple arms, each independently controlled from a remote console. Other systems, such as Versius from CMR Surgical, deploy several lightweight independent arms, each attached to a mobile base. The robots have to be carted near the patient.
Surgeons operate all these systems from a console using a magnified, high-definition, 3D view of the surgical field, which is often better than what they’d see with their own eyes. Da Vinci 5 adds sharper visuals and depth perception with two cameras, one for each eye. And because the cameras are held by a robot rather than a human assistant, the image is far more stable.
These platforms are already used in a range of operations. But they have weaknesses. Most require proprietary surgical instruments and methods to make extra space for robot docking and maneuvering during procedures. Staff training adds further complexity and cost, limiting where the systems can be deployed.
Humanoid robots, in contrast, are far more mobile and compact. Their human-like bodies could move through standard operating rooms, use conventional surgical instruments, and potentially be easier to incorporate into existing operating rooms.
The timing may also be right. Recent advances in electric components controlling their motion have made humanoid robots faster and more stable than their awkward, stumbling predecessors. Newer AI systems that predict full-body movement and provide feedback have improved robots’ balance and ability to adjust to real-world complexities. Humanoid robots are already stocking warehouses and winning marathons.
But surgery sets a higher bar.
We still don’t know how close humanoid robots are to meeting the requirements for surgical procedures, wrote the team. That’s what they set to find out.
Hello, Surgie
The new system consists of a surgeon’s control console and the robot itself. The surgeon wears a stereoscopic headset with a magnified 3D view of the surgical field and controls the robot with an input device. The robot translates the surgeon’s commands into movements in real time.
The team chose the commercially available Unitree G1 for the job. Unlike Da Vinci, which was built for surgery, G1 is a more general-purpose humanoid with dexterous wrists and multiple joints. The researchers customized the robot’s hands so that it can rapidly switch between surgical tools. Standing just over four feet tall and weighing roughly 77 pounds, the robot takes up a fraction of the space needed by conventional surgical robots.
Precision is key for laparoscopic surgery. Surgical instruments must pivot around a fixed site at the incision, allowing them to move freely inside the body without stretching or tearing neighboring tissues. After extensively mapping Surgie’s movements, the team identified a safe set-up with enough range of motion for most minimally invasive surgeries.
Surgie passed standard robotics benchmarks evaluating surgical skill for both humans and robots. But the real challenge came next. The team performed two gallbladder removal surgeries in a standard operating room. Both operations followed a typical workflow, with a lead surgeon and an assistant responsible for placing the camera, cleaning lenses, and swapping instruments.
Surgie collaborated with the human assistant to locate, identify, and remove the gallbladder with minimal damage to surrounding tissues, including the liver. During part of one procedure, a second humanoid briefly took over camera handling while the human assistant stepped aside.
Both operations went relatively smoothly. One involved minor bleeding and bile leakage from the gallbladder, but both were easily managed. In interviews, surgeons said controlling humanoid robots felt intuitive, particularly because they had two arms and could use standard surgical tools.
“We were surprised at how well Surgie meshed with our workspace and workflow,” said study author Nikita Thareja.
The system is still in early development. Surgie’s restricted reach required frequent repositioning and recalibration, adding more than three minutes each time. The robot also occasionally needed cooling breaks after overheating. In a real operating room, interruptions like these could increase risk by forcing surgeons to split their attention between the procedure and supervising the robot.
Still, Surgie has a leg up on conventional surgical robots: It can walk. Beyond assisting with an operation, it could potentially fetch surgical tools or help clean operation rooms between procedures.
The team is now refining the system to reduce control lag, particularly during long-distance teleoperation, and exploring ways to safely sterilize—or “scrub in”—a humanoid robot for the operating room.
“Our goal is an operating theater of the future, where humanoid robots and humans work side by side as an integrated team to deliver procedures to those in need, both in traditional hospital settings as well as in non-traditional, field medicine scenarios,” said Yip.
Companies once moved whole factories overseas to reduce labor costs. Now, workers a world away can operate local excavators, forklifts, and even humanoid robots with an internet connection.
Packaging potassium sulfate, a fertilizer vital to the planet’s food supply, is visually striking—not because of what you see, but because you don’t see much at all. In China’s Xinjiang region, home to the world’s largest deposit of the mineral, piling it up in warehouses creates dust clouds so severe that workers are forced to drive heavy machinery by feel.
Some companies are now turning to a technology that not only offers a way to see through the dust but also keeps workers from entering the warehouse at all. The system, developed by BuilderX Robotics, a Chinese tech company, uses cameras that are like night-vision for dusty areas. More significantly, operators drive excavators, loaders, and other machines from a remote office filled with rows of videogame-like stations. All they need is a 5G or satellite connection.
The ability to control physical machines from a distance is called teleoperation, and it could become a significant force of change in the global economy.
In Japan, the shelves of over 300 convenience stores are being restocked by robots monitored and sometimes controlled by workers in the Philippines. Düsseldorf airport was slated to begin testing shuttles driven by remote workers in May. A startup in Atlanta is offering robot security guards operated by remote staff, and last summer, a surgeon in France performed a teleoperated procedure on a patient in India.
While offshoring teleoperated jobs to overseas workers hasn’t yet become routine, Mark Graham, professor of internet geography at the University of Oxford, suggests the technology is worth our attention because it might enable companies to expand on their well-established habit of outsourcing jobs to places where labor is cheaper.
The use of remote labor isn’t new, Graham told SingularityHub. But teleoperation extends the logic of outsourcing to tasks that were previously thought to be “stubbornly local.”
“The novelty is less about the existence of remote labor and more about the kinds of work that can now be pulled into a planetary labor market,” he said. “Once that happens you can expect the usual pressures around labor arbitrage, control, and fragmentation to follow.”
It’s not clear we’re ready for the consequences.
BuilderX Robotics is a global leader in teleoperation for heavy machinery and a good expression of the changes ahead. Shaolong Sui, a graduate of Stanford University with a degree in mechanical engineering, founded the company in 2018 as a response to labor shortages in the construction industry in Asia.
“A shortage of trained operators isn’t a problem only in developed countries,” he told me. “Young people here in China don’t want to do this work. It’s dusty and dangerous.”
Rather than focusing on full robotic autonomy, which many construction companies have pursued over the past decade, Sui identified teleoperation as a more realistic way to move operators from harsh environments to safer conditions. Making use of the proliferation of low-cost sensors and 5G at the time, Sui completed a prototype in 2019. Today, his company offers teleoperation for 14 different industrial machines, including excavators, loaders, and bull dozers.
In our conversation, it was clear he hopes to improve working conditions for manual laborers. I lost track of the number of times he mentioned removing operators from dangerous worksites. “These workers deserve a better life,” he said.
BuilderX’s workstations do seem to have transformed some of the punishing work of an industrial site into a more white-collar experience, complete with tea and coffee break rooms and toilets down the hall. Sui said his solution allows construction firms to hire senior citizens or people with disabilities who, thanks to the videogame-like interface, can now operate heavy machinery. In another video, a Japanese woman who pilots an excavator proudly shows off her complex nail art, something she claims she couldn’t maintain when she worked in the field.
“Not only is this a much safer workplace, but the lifestyle benefits are that you can sit in an air-conditioned space, enjoy your tea, and when you go home, you’re still clean,” Sui said.
There’s no doubt the approach is safer for frontline workers like those in Xinjiang. Evidence suggests that high levels of potassium dust exposure can cause chronic bronchitis. While pulling someone from dangerous work is a good thing and that should be taken seriously, Graham told me, it doesn’t necessarily mean they’re free from exploitation.
“A worker can be removed from the physical site and still be subjected to intense surveillance, deskilling, isolation, fragmented contracts, algorithmic management, and downward pressure on wages. In other words, the risk can move rather than disappear,” he said.
Sui and Graham both agree there are plenty of forces that might slow the pace of outsourcing. Currently, none of BuilderX’s customers offshore work to overseas operators. But that doesn’t appear to be a technology constraint, as recently demonstrated by an operator in Poland controlling an excavator over 4,000 miles away in Beijing. On the technical side, latency—the delay between operator and machine—and reliability will shape the rate at which firms can choose to offshore workers. But it’s more likely to be limited by regulatory constraints in the form of licensing, insurance, and safety requirements.
That said, Graham believes the biggest force driving work overseas will be the same one that’s pushed clerical and service work offshore; the relentless pursuit to increase profit and reduce cost.
“If firms can hire people in lower-wage labor markets to operate expensive equipment thousands of miles away, many of them will try,” he said.
Most debates about AI and robotics focus on job loss due to automation. There is relatively little discussion about the risk of offshoring teleoperated work as the technology comes online. This is partly due to the hype surrounding physical AI, a Silicon Valley buzzword describing a world where fully autonomous robots cut humans out of the loop. But Graham says that when machines arrive people tend to incorrectly assume humans disappear.
“In many cases, what gets described as automation is really a reorganization of labor. Work gets broken apart, moved around, and hidden from view,” he says.
As is the case with AI, the robotics industry’s push toward full automation is still plenty reliant on a hidden system of faraway workers. Teleoperation provides training data for robots and is needed to help them deal with unexpected events. Consumer robotics startup 1X is selling a $20,000 humanoid that will sometimes need to be controlled by remote staff. It’s not clear how often future robots cleaning dishes in San Francisco kitchens will be steered by gig workers in Mumbai.
Robotaxi company Waymo already relies on human agents to assist, though not literally drive, vehicles stuck in difficult scenarios. The firm recently disclosed for the first time that some of these agents are based in the Philippines. This information, surfaced during US congressional testimony, immediately raised questions of oversight for safety-critical work: For instance, should a worker in Manila be required to get a California driver’s license?
Amid an already combustible US political environment, teleoperation could raise the heat even higher. Fueled by fears of Americans losing jobs to people overseas, Wyndham Hotels and Resorts, the parent company of La Quinta, was last year forced to respond to anger over a viral video depicting workers allegedly in India remotely handling check-in at one of their Miami hotels. As Graham points out, people tend to care more about outsourcing when it’s no longer hidden in a back office.
But outrage alone, he says, rarely defeats a business model that saves money. Due to network effects surrounding training, infrastructure, and other business process optimization, outsourced labor also tends to cluster in specific areas. This may already be happening in the case of Waymo, which could soon see the rise of something like a “driving district” in Manila. In the future, other types of teleoperated work could follow suit, giving companies a ready-made destination to shop for low-cost labor.
For Graham, it’s urgent that we begin requiring certification from independent bodies, which can better scrutinize a company’s production networks. At Oxford he directs Fairwork, a project aiming to improve labor practices in digital supply chains.
I asked Sui how he thinks his customers may reorganize their operations around this new ability to remotely control their machinery.
“We’re working with traditional industries, and so it’s not just about adopting a new technology. There are significant management changes they will have to navigate. You could call this transformation friction because they will need time to digest this new capability step by step,” Sui said.
Despite the fact they could use the technology to outsource work across national borders, none of his customers are doing so just yet. Sui used open pit mines as an example. In this case, where fully developed towns with schools and hospitals have built up over decades, his customers still cluster their workforce next to the sites where they operate. Instead of driving into the mine, operators work from an office and go home clean at the end of a shift.
BuilderX has deployed its technology at more than 100 sites in China, Japan, and parts of Europe. It’s now expanding into new markets including South America and the Middle East. When asked whether he thinks his technology will be used for transnational outsourcing, there’s no hesitation. “Oh yes, I think this is coming in the very near future.”
A tiny robot developed by Japan’s space agency operated autonomously on the moon for more than 100 minutes and sent a series of images back to Earth.
Exploring the moon’s surface lays crucial groundwork for future crewed settlements, and swarms of tiny robots could be the key. Now researchers have given the first demonstration of the idea after a palm-sized rover autonomously navigated the moon and transmitted images back to Earth.
The moon is a tough environment for robots. Its surface is strewn with craters and abrasive moon dust, and communication delays make remotely piloting vehicles a painstaking and risky process. The cost of launching and landing hardware and the real prospect of losing expensive equipment justifies an extremely cautious approach that can significantly slow down exploration.
One way around these challenges is to replace traditional rovers with many small, cheap, and hardy robot explorers, which could increase coverage and introduce redundancy. And now Japan’s space agency JAXA has given us the first compelling demonstration of the approach.
In a paper published in Science Robotics, JAXA researchers provide a technical report detailing the successful deployment of the agency’s LEV-2 robot during the its SLIM mission, which touched down near the Shioli crater in January 2024. LEV-2 is a three-inch-wide sphere that converts into a wheeled robot after landing. The robot operated autonomously for more than 100 minutes, covering an estimated 24 meters and relaying a series of images back to Earth.
“Although the capabilities of an individual small rover are inherently limited, the results highlight the potential of such platforms as independent explorers, capable of accessing environments beyond the reach of a primary large spacecraft,” the authors write.
Nicknamed SORA-Q—derived from the Japanese words for space and sphere—the robot weighs just eight ounces. Upon arrival, the shiny metal sphere splits open and expands horizontally, allowing its two hemispheres to become wheels that spin around a central shaft. This central area also features a front-facing camera and a tail to help stabilize the robot.
JAXA developed the device in partnership with Sony and toymaker TOMY. The design borrows directly from technology used in transformer toys that convert from vehicles into robots. But the team had to make considerable modifications to account for the harsh lunar environment.
One of the biggest challenges for any lunar robot is maneuvering in the dust, or regolith, that coats the moon’s surface. The fine, powdery material can be hard for smaller wheeled robots to navigate as they lack the traction of their larger counterparts.
To solve this problem, the team designed the wheels to rotate around a point slightly offset from their center, causing a lopsided spinning motion that lifts the rover up slightly on every rotation. This helps the wheels to dig into the surface and generate enough traction to keep moving in the loose regolith.
Communication delays also present a significant barrier to smooth operation, so the team engineered the robot to handle most operations autonomously. An onboard image-processing system allowed the rover to detect the SLIM lander in its camera feed and use this as a navigational reference point, estimating its own position relative to the spacecraft in real time.
Because of its diminutive size, it was impractical to give SORA-Q the equipment needed to communicate directly with Earth, so the team paired it with a hopping robot called LEV-1 that can transmit data. Power constraints and narrow communication windows still cap the amount of data the robot can send to Earth, so SORA-Q has an onboard image-processing algorithm that picks out the best photos to share.
Due to power and mass constraints, the team fitted the robot with a low-power chip designed for small devices rather than complex tasks like image processing. The algorithm relies on a very simple approach—it detects the SLIM lander’s distinctive gold insulating material and then picks the photos where this is featured prominently in the frame.
Around seven minutes after activation, the rover had moved roughly five meters from the lander, selected the two best images from 12 it had captured, and transmitted them to LEV-1. One of those images actually proved unexpectedly useful as it showed the lander had landed at an odd angle with its solar panels facing the wrong direction. This gave ground teams critical information that helped them diagnose the spacecraft’s operational status.

But the system wasn’t flawless. It lost some data in transmission, partly because LEV-1’s hopping maneuvers appeared to disrupt the wireless link and partly due to changing antenna orientations as the rover moved. The team also lost telemetry data before the mission ended, making it impossible to determine exactly how far the rover ultimately traveled or when it stopped working.
Still, the mission was strong evidence that small, cheap vehicles like SORA-Q could greatly expand the scope of robotic exploration. That could prove invaluable as we attempt to scope out promising locations for future scientific missions or even permanent bases on the moon.
