In my Robotics and Mechatronics course, I was challenged to create a line-following robot using a line sensor. My partner and I created a robot that can functionally follow a line using a PID controller and stop 2 inches away from a barrier using a proximity sensor. Calibrating the PID to avoid overshooting while correcting errors and handling 1 and 0 inputs from the line sensors to indicate direction was a great learning experience. The chasis of the vehicle was laser-cut, as was the wiring housing. A 5-volt portable battery powered the Raspberry Pi, and a 12V lithium-ion battery powered the motors through the H-Bridge. The course was Pokemon themed so we decided to decorate the robot accordingly.
