Robots are the inventions of the modern world that has reduced manual efforts to a greater extent. Humans usually utilize robots to do works that are dangerous, dirty, and difficult. Mobile robots are operated using remote controlled mechanism. They are agile and can move from one place to another using remote mechanism. This paper includes the information on a novel hybrid locomotion mechanism for small mobile robots. By hybrid locomotion mechanism, we mean that the wheel and track type motion are merged to increase the agility of the mobile robots. This not only makes the robot flexible, but also adds up a hybrid and interchangeable movement. The robot can move in any direction. The robot transforms from track mechanism to wheel mechanism by using a switchover module. A switchover module is a track sensor unit and is usually operated by the old school wheel and track mechanism. The wheel exerts force on the track, making the switchover module move in upward and downward direction supporting the movement of the wheel in rotatory motion. It is assumed and believed that the hybrid locomotion mechanism is able to perform in rough grounds as well. © 2019 ICIC International. All rights reserved.
