Japan shows off disaster-response robots

Japan displayed a pair of two-legged humanoid robots on Wednesday that can operate in harsh conditions as the country prone to earthquakes and volcanic eruptions prepares for the next catastrophe.

Simulating work in a tunnel after a quake, two slender robots with tiny heads attached with sensors walked through fake debris to extinguish a fire during a demonstration at the International Robot Exhibition in Tokyo.

The four-day event which kicked off on Wednesday, is held once every two years in Japan's capital.
