Abstract : This article presents the design and development of a printed circuit board (PCB) for any differential drive robot with dual brushless direct current (BLDC) motors. The movement and agility of the wheeled rover depend on the synchronization and regulation of these motors, highlighting the importance of the PCB. This article discusses the pros and cons of the controller PCB, as well as its design. It also covers circuit diagrams, block diagrams, and the performance of the controller circuit. Communication interfaces are crucial for seamless integration into robotic systems. The firmware incorporates sophisticated control algorithms to ensure optimal performance and responsiveness of the rover. Experimental results demonstrate the controller's capability for precise motion control, underscoring its potential applications in exploration and surveillance robotic missions. The response time of the PCB, observed during experiments, is impressive. After transitioning from analog to digital signals, the PCB now facilitates faster communication. The UART communication protocol is utilized in the PCB. Beyond enhancing rover agility, the presented controller PCB design con-tributes significantly to the field of robotics, providing a robust and adaptable solution for platforms driven by twin BLDC motors. Implementing multiple communication protocols is essential to increase the feasibility of incorporating various sensors, which constitutes the future scope of our planning. Additionally, acquiring sensor data, such as adjusting motor operation according to encoder values to establish a closed-loop system, is also part of our envisioned future developments.
