Design of non-conventional chain drive mechanism for a mini-robot

This paper describes the design of a non-conventional chain drive mechanism for a mini-robot. A mini-robot named RUDYCUDY™ was designed. Chain drives are normally used when power or motion or both of them are to be transferred over a short distance. Various systems were available in the markets that had certain standards. To drive small scale robots no standard chain was available. In this study a roller chain was designed because of its simplicity, strength, ability to work in harsh environment and little requirement for lubrication.
