China is turning its attention to future space mining. A multifunctional space mining robot is being pursued by experts at the China University of Mining and Technology (CUMT).
Liu Xinhua at CUMT explains that the space mining robot differs from the widely known humanoid robots and robotic dogs.
Instead, the mining robot adopts a six-legged design, featuring three wheel legs and three claw legs, which would allow it to function efficiently in microgravity conditions.

Claw system
“In space, objects do not stay in place like they do on Earth due to the lack of gravity. If you push something, it will float away, just like astronauts inside a space station,” Liu told China Central Television (CCTV).
The research team took inspiration from insect claws and designed a special claw structure to improve the robot’s grip.
“This claw system is an array-type structure that enhances adhesion and gripping ability in microgravity environments. It allows the robot to stay anchored while collecting samples and move efficiently based on the terrain,” Liu added.

Preliminary testing
The space mining robot is equipped with a “biomimetic” six-legged movement system. Each leg has wheel and anchor configurations, enabling the robot to traverse rough and uneven surfaces on asteroids, CCTV reports.
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems.
Prototype hardware has already undergone preliminary testing to validate the team’s approach.
Liu said the robot was able to walk, anchor itself, and even collect samples in a simulated lunar soil environment.

Lunar research base
In related work, China is aiming to realize a crewed Moon landing by 2030. By 2035, the country has stated it wants to establish the core structure of a Moon base, “with the possibility of long-term unmanned operation with the prospect of ensuring a human presence on the Moon.”
The International Lunar Research Station (ILRS) is targeted for the Moon’s south pole region, and to establish a lunar research station connecting the Moon’s south pole, equator, and far side by 2050.
