RunBot is a biomechatronic design. It has achieved a relative walking speed of 3.5 leg-lengths per second, which is much faster than the current world record of biped walking robots, 1.5 leg-lengths per second, and is even comparable to the fastest relative speed of human walking.

TOKYO (AFP) - A Japanese robot maker on Tuesday unveiled what it called the world's first prototype of an artificial hand with "air muscles" that can do even delicate work like picking up a raw egg.
