Robot manufacturers across the country are incessantly developing and upgrading research robots for the quick recovery of the power plant in Fukushima. Topy Industries developed a small research robot that can revolve even in a halfpace about 70 cm wide carrying such devices as camera and dosemeter. It employs the rubber underbody and arms to go up and down a staircase. The robot named Survey Runner will be lent to Tokyo Power Plant by the end of this month.
Existing robots need at least a 100 cm wide halfpace to ascend and descend a staircase, but Survey Runner needs only a halfpace about 60 cm wide because it is much smaller thanthe existing robots. In addition, the arms can make it ascend 45-degree wet steps inside the buildings of the power plant. Because it allows for wired operation, it can be operated even if it is blocked by a thick wall. It comes with about 400 m fiber cable, and the operator can run the Survey Runner in a remote place. Even if it overturns, it can recover its feet thanks to its low center of gravity.
