Toshiba has developed a remote-controlled tetrapod inspection robot with camera and dosimeter, designed to investigate risky areas, such as Fukushima nuclear power plants.

The multiple joints of its legs are controlled by a movement algorithm that enables the robot to walk on uneven surfaces (like Boston Dynamics’ Big Dog), avoid obstacles, and climb stairs to get access into areas can’t be reached by wheeled robots (such as some iRobot models) or crawlers.

It also carries a companion smaller robot with a second camera for constricted locations.

Toshiba plans to add the ability to install shielding, stop flows of water. and remove obstacles.
