A Robotic Chemist Could Whip up the Perfect Batch of Oxygen on MarsHumans on Mars will need oxygen, and Mars’ atmosphere is pretty anemic when it comes to the life-sustaining element. NASA’s Perseverance rover successfully extracted oxygen from CO2 in Mars’ atmosphere, but there are other ways to acquire it. There seem to be vast amounts of water buried under the Martian surface, and oxygen in the water is just waiting to be set free from its bonds with hydrogen.
On Earth, that’s no problem. Just run an electrical current through water, and you get oxygen. But Mars won’t give up its oxygen so easily.
NASA’s Perseverance rover extracted oxygen from CO2 in Mars’ atmosphere, another first for the mission. It was an exciting achievement since future human visitors to Mars will need it to breathe and to create rocket fuel. But a team of Chinese scientists are developing a different approach.

Universe TodayThey’ve shared their results in a paper titled “Automated synthesis of oxygen-producing catalysts from Martian meteorites by a robotic AI chemist.” It’s published in Nature Synthesis, and the lead authors are from the Key Laboratory of Precision and Intelligent Chemistry at the University of Science and Technology of China, Hefei, China.
“Oxygen supply must be the top priority for any human activity on Mars because rocket propellants and life support systems consume substantial amounts of oxygen, which cannot be replenished from the Martian atmosphere,” the authors write. (NASA scientists might disagree with that statement.)
Instead, Chinese researchers think that solar energy can be used to produce oxygen from Martian water. But it won’t be the simple electrolysis from science class. Instead, they intend to employ catalysts.

The oxygen evolution reaction is a bottleneck in electrolysis, and scientists sometimes call electrolysis “sluggish.” On Earth, scientists know which catalysts can overcome the bottleneck. But conditions are different on Mars than they are on Earth. Scientists can’t just transpose methods that work on Earth onto Mars. The trick is finding the appropriate catalysts available on Mars. Scientists call them oxygen evolution reaction (OER) catalysts.
Here’s the problem: there are over three million possible catalysts on Mars. How can scientists work through all those possibilities when the communication delay between Mars and Earth can be up to 20 minutes long? It’s not practical.
This is another situation where robotics and AI can solve a problem, according to the research team.
“Here we demonstrate a robotic artificial-intelligence chemist for automated synthesis and intelligent optimization of catalysts for the oxygen evolution reaction from Martian meteorites,” the researchers explain. “The entire process, including Martian ore pretreatment, catalyst synthesis, characterization, testing and, most importantly, the search for the optimal catalyst formula, is performed without human intervention.”
China doesn’t have a functioning spacecraft on Mars that can do some of this work. Fortunately, nature has delivered samples of Mars to Earth in the form of meteorites. The researchers used small amounts of five types of Martian meteorites as feedstock in their automated system.

The system then synthesizes catalysts, optimizes them and tests them. The system searches for the optimal catalyst, all without human operators. Image Credit: Zhu et al. 2023.

Image Credit: Zhu et al. 2023.To illustrate how effective this fully automated, robotic AI system is, the researchers calculated how long it would take for humans to complete the same tasks using typical ‘trial and error’ methods.
The trial and error method is difficult because of what researchers call chemical space or material space. There are a confounding number of variables that need to be tested, and they occupy an enormous chemical space. “Designing a catalyst from a given list of elements requires the exploration of a vast chemical space,” the researchers explain, “which poses a daunting task using the conventional ‘trial-and-error’ paradigm.”
With the five Martian meteorites as feedstocks, there are an estimated 3,764,376 potential catalysts. That creates lifetimes of work for human scientists. “Finding the optimal formula would require 2,000?years of human labour to finish such a screening, where each complete experiment takes 5?hours, at least,” the researchers write.
Robotic chemistry has made serious advances in recent years, something the researchers say can be leveraged for use on Mars. They point to research by Cooper et al. in 2020. In that effort, a team of researchers used a mobile robot to tackle the chemical space and search for improved photocatalysts for hydrogen production from water. “The robot operated autonomously over eight days, performing 688 experiments within a ten-variable experimental space,” Cooper and his colleagues wrote in 2020. That’s 86 experiments per day.
With this new research, which the researchers call a ‘proof of concept study,’ the trend for robotic/AI chemistry takes another step.
It started with the AI. “Within six weeks, the AI chemist built a predictive model by learning from nearly 30,000 theoretical datasets and 243 experimental datasets,” the researchers explain. Eventually, the system delivered an exceptional catalyst made up of several metals. The material catalyzed the oxygen evolution reaction—the bottleneck in the electrolysis of oxygen from water—for 550,000 seconds (about 153 hours.) Furthermore, the catalyst was effective at -37 C, a typical surface temperature on Mars.
This schematic shows the robotic/AI system in greater detail. LIBS stands for Laser-Induced Breakdown Spectroscopy. LIBS produces a small amount of plasma on the surface of the sample that aids study. While complex, simple electrolysis is still the heart of the system. Image Credit: Zhu et al. 2023.

This is an impressive development. The fact that it’s all done in situ is also compelling.
“The established protocol and system, which are generic and adaptive, are expected to advance automated material discovery and synthesis of chemicals for the occupation and exploration of extraterrestrial planets,” they conclude. But what’s next?

That mission will be Tianwen 3, the third in the Tianwen line, and China hopes to beat NASA/ESA to the punch by returning a sample to Earth in 2031.
It seems unlikely that China can also shoehorn a robotic/AI chemistry experiment into a sample return mission, but you never know. The CNSA is ambitious and eager to measure up to NASA’s record of success.
If they can, it’ll be an extremely impressive feat and a big leap forward in Mars exploration.

DARPA-funded 'Inchworm' robots could help us build moon bases. Here's how
Josh DinnerTue, December 5, 2023 at 9:00 AM EST·3 min read
1A gold-foil-wrapped octagonal lunar probe is landed on a grey surface. A white robotic arm is attached to the probe's flat top, next to an antenna.
A maneuverable robot from Japan-based startup GITAI has made the list of technologies chosen for a lunar infrastructure development study from DARPA.
DARPA, or Defense Advanced Research Projects Agency, the research and development organization of the United States Department of Defense, announced the 10-Year Lunar Architecture (LunA-10) capability study study in August this year, seeking to unite isolated endeavors within the scientific community in order to create an advanced technological infrastructure to support future activities in space and on the surface of the moon.
One of the companies chosen for LunA-10, GITAI, is a space robotics startup with a focus on making laborious tasks in space safer and more affordable. As part of that aim, the company has designed modular "Inchworm" robots with interchangeable, task-adaptable hardware, capable of performing complex tasks in microgravity and the lunar surface environment.
The robots' modular design allows for easy incorporation into other technologies, and is in-line with DARPA's LunA-10 vision of an incorporated technological infrastructure for space and lunar exploration.

Several companies were announced at the October 11 meeting of the Lunar Surface Innovation Consortium (LSIC), "subject to successful contract negotiations," said Dr. Phil Root, Director of the strategic technology office at DARPA, at the October meeting.
GITAI was one of the companies listed under the Construction and Robotics section of Root's presentation, and has now been officially selected for the LunA-10 study.
GITAI tested this technology inside the Nanoracks Bishop Airlock aboard the International Space Station (ISS), with its "S1" robot, which successfully maneuvered dexterous tasks like pushing buttons and switches, as well as the assembly of test components resembling solar panels or antennas.

A second robot, the "S2," is being launched to the ISS in early 2024, with the goal of demonstrating the technology's servicing capabilities on the exterior of the space station. Neither the S1 or S2 reflect the full abilities of GITAI's Inchworm being included in DARPA's LunA-10 study, but are "technologically akin" to the developing robot, according to a GITAI release.
"We're both humbled and thrilled to be chosen," said GITAI found and CEO Sho Nakanose as a part of the company's LunA-10 announcement. Nakanose sees the company's mission as being about more than just robotics. "It's about forging a new era of lunar infrastructure," he said, adding, "our innovative approach, leveraging modular robotics, is a catalyst for reshaping how we envision the moon."
According to an August statement from DARPA, selection for the study makes GITAI eligible for up to $1 million in funding, with a fast timeline to realize the Inchworm's technological progress. Companies selected for LunA-10 are expected to update the scientific community on their progress during an April 2024 meeting of the LSIC.

China’s Unitree to livestream world’s first robot boxing match, G1 humanoids to take part
Unitree has announced that it is planning to livestream what could be the world’s first robot boxing match very soon.

Chinese robotics company Unitree has announced that it will soon livestream a boxing match between two humanoid robots. According to reports, the company plans to use a pair of G1 robots for the fight.
Unitree has already released a promotional video to support the announcement, showing its robots sparing with a human and another robot. The company has announced that the robot-versus-robot fight, entitled “Unitree Iron Fist King: Awakening!” will take place “in about a month.”
No other information has been released about the planned fight. It is also unclear exactly which models of Unitree’s robots will be used for the match.
The 4.3-foot (1.32 m) tall Unitree G1 is the most likely candidate for the fight. Another option is the company’s H1 model, which stands at 5 feet 11 inches (1.8 meters) and could also appear.
Robot boxing is now a thing
This model features greater computing power and smoother motion control; it’s considered the company’s flagship robot. Whatever the case, the promo video that Unitree released gives us a flavor of what such a fight could look like.
As previously mentioned, the first section of the video shows a Unitree robot fighting a human opponent.
The G1 in this fight appears more sluggish than its human opponent but can quickly recover once hit to the ground. However, compared to humans, the robot is noticeably slower to react and is not as fluid when performing actions like dodging blows and keeping its balance after being hit.
The second fight in the video shows two robots facing off against one another, foreshadowing the event to come. Interestingly, however, the video also shows the robots showcasing more advanced Kung Fu moves, raising questions about whether the video may have been enhanced before release.
This news comes only months after the company made new with its robots showing off some impressive dance moves. back in January, Unitree released footage of their H1, H1-2, and G1 humanoid robots to dance like a human.
This footage showed off the lifelike motions in the new datasets, which will help users experiment using humanoid robots to interact more naturally in the real world.
Prepare for battle
Unitree has been working hard to improve full-body movement control and taught the robot human-like walking, dancing, a few moves from well-known athletes and a kung fu trick.
But the robot’s boxing training has not yet reached its end. It can be assumed that Unitree will make a few more improvements before the announced fight.
According to reports, Unitree uses a motion data set created using LAFAN1 motion capture technology as the basis for full-body control. This dataset enables lifelike movements, considering the robot actuators’ end-position constraints, joint positions and speed limits.
The H1 is Unitree’s base commercial model, available for as little as $16,000 apiece. The G1 is an affordable yet cutting-edge humanoid robot aimed at researchers and hobbyists.
It is smaller than the H1 but is also very agile and can fold to a size that a single human can carry. The G1 comes complete with many of the same features as the H1 and can run almost as quickly at two meters per second.

This is a follow up report on robots becoming capable...
Once again, the field of progress is China.
First human-robot marathon
According to the robot’s creator, Tang Jian, who is also the chief technology officer behind the Beijing Innovation Centre of Human Robotics, the robot’s long legs and onboard software both aided it in its impressive feat.
“I don’t want to boast, but I think no other robotics firms in the West have matched Tiangong’s sporting achievements,” he said.
Jian added that the robot’s battery needed to be changed only three times during the race. As for other robot entrants, many didn’t perform as well.
In particular, one robot fell at the starting line and lay on the ground for a few minutes before getting up and joining the race. Yet another crashed into a railing, causing its human operator to fall over.
According to Sky News, all robot entrants were accompanied by human operators, some of whom had to assist the machines during the race physically. Other robot runners also wore running shoes, with one donning boxing gloves and another wearing a red headband saying “Bound to Win” in Chinese.
Fun for all
As for the course, it was specifically planned to verify the physical capabilities of the robots. This included a mixture of legs with flat surfaces, inclines, left turns, and right turns.
A strict maximum time limit of 3 hours and 30 minutes was established before the race.
According to Reuters, many of the robot entrants’ creator companies spent weeks testing their competitors before the race. This led some Beijing competitors to compare the race to more traditional car racing, given the engineering and navigation requirements for the robots.
“The robots are running very well, very stable … I feel I’m witnessing the evolution of robots and AI,” said spectator He Sishu, who works in artificial intelligence.
This race is just the latest in a series of robots competing in marathons in China, following the “world’s first” all-robot event held in March 2025. It is, however, the first that pitted robots directly against human runners.
