Bipedal

Bipedal beings on land motivate themselves by two leg?s. Through evolution, many animals have come to be bipedal, the closest example being humans?. Bipedals are found among many branches of animal life, not just mammals: Ostriches alsong with many other birds are bipedal, as are kangaroos. Bipedals are almost exclusively land living, as sea animals rarely have use for legs unless they live on the bottom of the sea, where a larger number of legs is favoured.

Until recently, bipedal robots have been very difficult to construct. Increasing computer power, however, has enabled two legged robots in recent time.
