Dual arm mobile robot (MEISTeR)
[ Nuclear Power Generation ]
[ ENERGY ]

The MEISTeR, an improved version of the MARS series, has been developed.
The MARS series of mobile manipulators for work developed at the time of the criticality accident at JCO in Tokaimura in September 1999. It was an epoch-making robot capable of traveling on uneven ground including stairs and equipped with two work manipulators. We modified our in-house robot with the same specifications to apply it to the Fukushima Daiichi Nuclear Power Plant, which was damaged by the Great East Japan Earthquake, and used it for various operations. Specifically, for the first time in the world, we have successfully hollowed out a concrete into a cylindrical shape and taken back from a power plant, by complete remote control.
