Japanese Robot Quince
The most advanced Japanese inspection robot Quince has been used since July 2011 for missions inside the reactor building.

Unveiled in April 2010 by the Chiba Institute of Technology, Tohoku University, and IRS, Quince consists of a main body incorporating two wide crawler belts, and four free-moving pairs of wheels that extend like arms from the corners. Making full use of these body parts, the adeptly maneuvers its way around all kinds of terrain, from stairs to rubble.
