Locomotion Systems in Robotic Application

In this paper we try to explain about the principle of the most popular locomotion systems and their different types especially in robotics, also about the history and evolutions of some systems like wheels, tracks, legs and reconfigurable robots then we will describe the most modern locomotion systems in nano robots. In order to prepare this paper we have used our experiments in different robotic projects which we have done in Islamic Azad University of Mashhad (Robocup Lab.) and also the results of other researchers which have been reported in international papers and journal.
