This rover is part of Japan's contribution to the Artemis program and is designed to enable long-duration human exploration of the Moon's polar regions.

GITAI, a U.S.-headquartered space robotics company, announced that its Japanese subsidiary, GITAI Japan Inc., has been awarded a contract by the Japan Aerospace Exploration Agency (JAXA) to conduct a concept study for a robotic arm system intended for use on a pressurized crewed lunar rover. This rover is part of Japan's contribution to the Artemis program and is designed to enable long-duration human exploration of the Moon's polar regions.

The objective of this study is to define the design and specifications for a robotic arm system capable of supporting lunar science operations primarily during uncrewed periods, while also providing support during crewed missions when needed. The arm will be tasked with performing a range of mission-critical operations, including regolith excavation, rock and soil sample collection, unloading, handling and installation of large payloads such as scientific instruments and observation equipment. It will also enable science activities through both remote and autonomous control capabilities. These functions are expected to significantly expand the scope and duration of lunar surface research.

This contract builds upon GITAI's strong track record in developing and demonstrating advanced space robotics technologies. Notable achievements include:

ISS Demonstrations: Successful technical demonstrations of GITAI's robotic arms both inside and outside the International Space Station (ISS), performing autonomous structure assembly and maintenance tasks.
LEO Satellite Validation: In 2024, GITAI successfully launched and operated its first in-house developed 16U-class satellite in low Earth orbit (LEO), validating key satellite bus systems, including attitude control via reaction wheels and orbital maneuvers using propulsion systems.
Lunar Readiness: GITAI's inchworm-type robotic arm has completed rigorous environmental testing—including regolith exposure, thermal vacuum, vibration, and radiation tests—achieving Technology Readiness Level 6 (TRL-6) for operations in the extreme conditions of the lunar South Pole.
U.S. Expansion: GITAI has fully relocated its headquarters and manufacturing operations to Torrance, California, and secured U.S. permanent residency status for its management and core technical team. The company has been awarded contracts by leading U.S. agencies such as NASA and DARPA, as well as major U.S. commercial space companies.
This concept study represents a significant step forward in enabling autonomous and remote-controlled lunar science operations and supporting sustained exploration through robotic labor on the Moon.
