Abstract– A rover is a vehicle for driving over rough terrain, especially one driven by remote control over extraterrestrial terrain. It uses a suspension system that has 6 wheel with provide great stability. We aim to introduce the mechanism of the rocker bogie or the rover as a suspension mechanism of normal vehicles.
The idea is to replace the normal vehicle chassis with that of the rocker bogie followed by the use of spherical wheels. The following idea tends to encounter various problem that is faced by a normal chassis and also by a normal cylindrical wheel.
Keywords – Rocker-bogie, Suspension, Spherical wheel,Omnidirectional movement.
INTRODUCTION
Aditiya. V [1] mentioned, a rover is a vehicle for driving over rough terrain, especially one driven by remote control over extraterrestrial terrain. Robotic rovers are used extensively for exploratory and reconnaissance purposes in the fields of scientific exploration and defense. This project focuses on the design and development of a rover with autonomous driving and environmental sensing capability. It can be used as an exploratory rover, providing information
about the terrain and surrounding atmosphere. It can also be used as a surveillance robot to alert people in areas with security threats like national borders, terrorist occupied territories etc., where it is difficult for humans to work. The rover will be having a Rocker Bogie Suspension system with 6 wheels for greater stability in maneuvering over obstacles.
Nitin Yadav et al. [2] mentioned that the place, where the value of gravity remain lower than earth’s own gravitational coefficient, at that place the existing suspension system fails to fulfil desired results as the amount and mode of shock absorbing changes.
