Design and Implementation of a Bluetooth-Driven Rocker-Bogie Robot

The rocker-bogie mechanism-based rover is a six-wheeled robotic system for versatile terrain adaptability and efficient mobility. Powered by DC motors controlled via an Arduino Mega, the system incorporates an L298N motor driver and an HC-05 Bluetooth module for wireless command reception through the Serial Bluetooth Terminal app. A PID algorithm ensures precise motor speed control, maintaining stability and responsiveness without relying on external sensors. The rocker-bogie suspension distributes weight evenly across all wheels, enabling obstacle traversal and improved traction. Key challenges addressed include power management, motor synchronization, and PID tuning, with solutions focusing on optimizing hardware integration and software algorithms. This project demonstrates an efficient and scalable approach to building terrain-adaptive rovers for exploration and research applications.
