A Low-Cost Rough Terrain Explorer Robot Fabrication Using Rocker Bogie Mechanism

Rocker-bogie mechanism is proven and renowned for its excellent performance in all types of exploration robots, especially in Mars rover robots. This paper aims to fabricate a low–cost explorer robot with a rocker-bogie mechanism that can run in all sorts of terrains. As the explorer robot is a prototype version of the Mars rover robot, the entire structure's size is confined. Only the mechanism is demonstrated using standard DC motors and wheels. A wireless communication system is implemented using internet of things technology, and a gas sensor is placed in the robot to collect the surrounding environment's gas level data. In the end, performance tests are accomplished to check the rocker-bogie mechanism's stability, and the sensor's data analysis is done.
