MAR-C comprises four modules: a platform, a telescopic ladder, a robot arm and an end effector module for attachment of various tools. It was developed by the New Energy and Industrial Technology Development Organization (NEDO), with the aim of being used for work at the Fukushima Daiichi Nuclear Power Station. The robot can perform various tasks, including opening/closing of valves and radioactive decontamination work.
The 4-ton robot is able to travel on 15° slopes and reach speeds of 6 kilometers per hour (km/h) on flat surfaces. Its battery enables continuous operation for 5 hours, even when the manipulator is being used at a height of 8m.
MHI said that it intends to "disclose technical data pertaining to the MARS-C's various connecting parts in order to enable the development of modules by other companies."
