The robot capitalizes on the inherent stability of the ape's quadrupedal stance without losing the chimp's versatility in climbing, grasping and moving over all types of terrain.

"(Chimps) have quite good quadrupedal walking abilities but they can also perform stand- up motion and walk on two legs -- their ability to do this is greater than other animals," says researcher Daniel Kuhn.

"They can choose -- if the environment won't let you move in a stable fashion on two legs they can choose four. When the environment improves, two legs allows you to get a better view over the field," Kuhn says.

The robochimp's sensors include a pressure sensor array of 43 individual force sensing resistor (FSR) sensors. It also has six additional FSR-sensors used for collision detection.

The research team are studying how to transfer from four-legged to two-legged motion patterns. They say this system gives us hints as to how humans evolved to walk on two legs.

The research agency is also looking at other types of space rovers. The locomotion of the scorpion and the mantis is being studied to create robots that have the stability of four legs but with the ability to manipulate material with their forelegs.

A space climber - a free-climbing robot designed to scale the inclines of craters - is put through its paces at the Bremen center's lunar habitat.
