A proposal by Komatsu has been chosen as an eligible target of technology related to autonomous construction on the moon.
The proposal, the Development of Digital Twin Technology for Lunar Construction Equipment, was submitted to the Project for Promoting the Development of Innovative Technologies for Outer Space Autonomous Construction. The Project is lead-managed by Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) with collaboration by Japan’s Ministry of Education, Culture, Sports, Science and Technology.
The project is part of MLIT’s Strategic Program for Accelerating Research, Development and Utilization of Space Technology (Stardust Program).
Under the leadership of the Council of Promoting the Development of Innovative Technologies for Autonomous Construction, an inter-ministry collaboration body, all selected companies and organizations will conduct research and development of their individual technologies, according to Komatsu.
In the ongoing three-year, mid-term management plan, to be completed in the fiscal year ending March 31, 2022, Komatsu is working to achieve safe, highly productive, smart, and clean workplaces of the future by advancing products (automation and autonomy of machines) and processes (optimization of construction operations). Concerning the selected Development of Digital Twin Technology for Lunar Construction Equipment, Komatsu will utilize accumulated technologies in both products and processes.
In a press release, Komatsu noted the complicated nature of construction on the moon's surface and suggested that digital twin technology can precisely recreate site conditions and machines.
To develop this technology, Komatsu will conduct a feasibility study to verify the possibility of developing high-precision digital twin technology, the basic technology of lunar construction equipment. Specifically, Komatsu will create and operate a hydraulic excavator in cyberspace and compare its movements with actual equipment on Earth to verify the simulator's precision. Komatsu will also set the surface conditions of the moon as cyberspace, and check the movements of the excavator in the simulator in order to identify the issues facing our lunar equipment.
