Abstract: This project is a Prototype model of “TRI - STAR WHEEL ROVER”. This project describes the mechanical design and development of Tri-Star wheel system for surveillance mobile robot. The robot will be used to enter potentially dangerous disaster site in search of human survivor and to collect some related information for rescue team. Surveillance mobile robot need to be able to overcome natural and virtual obstacles such as stairs which are the most known obstacles in the collapse buildings. The vehicle has four set of wheels arrangement to support its weight when it moves over the flat terrain. Each wheel frame consists of three sub-wheels attached with the sun wheel through three idle gears.

Keywords: Tri Star wheel., transporter, flat terrain etc.
