In nature, there are many types of terrains on which traditional wheeled and tracked vehicles can not move, but mammals can freely. This has fully shown the advantages of the four legged moving method. Inspired by these animals, researchers have done much indepth study on quadruped robots, and have made substantial achievements. This paper reviews the development status of quadruped robots in domestic and abroad, summarizes the key technologies in this field, and points out the development tendency.
