Toshiba shows four-legged robot for nuke disaster

YOKOHAMA, Japan (AP) — Toshiba Corp.'s four-legged robot is designed to help at the meltdown-crippled Japanese nuclear plant, climbing over debris and venturing into radiated areas off-limits to human workers.

But the machine took a jerky misstep during a demonstration to reporters Wednesday, froze with its leg up in the air, and had to be lifted by several people and rebooted.

Tokyo Electric Power Co., the utility that operates Fukushima Dai-ichi plant, said it was considering using the robot to look at a highly radiated part of the plant called the suppression chamber.

No human worker has been able to go there after the March 11, 2011 tsunami disaster that set off meltdowns and explosions at Fukushima Dai-ichi.

Toshiba, which also makes reactors, said it was ready to go if TEPCO gives a go-ahead.
