英文摘要：

A literature survey of researches on snake-likes was provided regarding morphology, modeling of kinematics and dynamics, locomotion control and stability. The analyses and summary were made according to the two-dimensional and three-dimensional locomotions. Classifications of snake-like robots were presented due to the differences of structures and movement types. Finally, the development of snake-like robots in future was predicted.
