In December 2021, the Japanese robot company Gitai tested its R1-rover, ordered by Jaxa and intending to travel to the Moon. A video released a few months later makes it possible to admire the device’s capabilities under realistic conditions that reflect the properties of the lunar regolith.
In parallel with the Artemis program, some space agencies are preparing their next arrival to the Moon with rovers. This is the casein collaboration with the Japanese company specializing in , Gitai. In September 2020, Jaxa announced the establishment of a collaboration with the private company, with the aim of designing assigned to carry out missions in space.
For this purpose, Gitai has developed a multifunction rover, soberly called R1. In December 2021, the properties of R1 were tested under realistic conditions on a surface that mimicked a plain on the Moon and its specificities. In a video released in February 2022, the robot impresses with its fluidity and its capabilities. The rover can thus easily maneuver and change direction, overcome natural obstacles or even collect objects on the ground. The experiment took place on the Sagamihara campus in Japan.
A marvel of technology
The R1 is equipped with four legs, the wheels of which, multi-directional, allow the rover to quickly adjust its position. The test shows that the device is capable of overcoming medium-sized obstacles and rocks while raising or lowering the rover’s trunk. Thanks to its mobility, it can also climb slopes whose slope is estimated at between 15 and 20 degrees.
Two articulated arms located on the front of the robot make it possible to perform regolith collection operations on the ground. Grippers located at the ends of the arms can use a small shovel to drop the moon’s dust samples into a container, which is then sealed by the rover before being stored in a container. The arms, which are divided into several parts, give the R1 a wide range of motion. Remotely controlled by an engineer, the device performs precise and technical movements: It can easily detach a strap from a package, move and use tools. Gitai exhibits its know-how by having its rover builtand a set of solar panels. R1 performs with precision the movements required for the assembly of the structure, by screwing the supports or by adjusting the position of the solar panels.
R1, more effective than a human?
The collaboration established between Jaxa and Gitai aims to democratize robot missions to space and the Moon. L ‘wants to monitor operations at reduced financial cost, with robots working efficiently where humans could not walk. On his side Japanese company reveals its ambition: and Martians as early as the 2040s and beyond.
As for the R1 rover, the impressive technical demonstration in December 2021 was to confirm the Japanese space administration in its ambition of robotic missions to the Moon. Gitai states during the video presentation of the rover that the latter could quickly make its first turns in the lunar dust as early as 2025.
