Japan develops its own UGVs, up to 10 tons, for its military

Japan's Acquisition, Technology and Logistics Agency is researching domestic unmanned ground vehicles in three weight categories, from under one ton to a heavy class of five to ten tons. A Ground Systems Research Center display showed a small four-track cargo carrier, a wheeled utility platform in the one-to-two-ton range and a larger tracked vehicle with a flat payload deck. The work covers off-road mobility, self-position estimation and coordination with crewed vehicles, with some prototypes still under construction. The projects are exploratory designs presented at an agency technology symposium, not a confirmed purchase of operational robotic combat vehicles by Japan's ground forces.
