Line followers robot using PID controller

Robot becomes widely used in industrial due to their characteristics. Robot able to work in 24 hours continuously without feeling tired unlike human that confine to certain time. The cost to setup the robot nowadays becomes more affordable and their long term prospect is bright judging from their capacity to perform. But in reality, there is no robot able to function perfectly and still making error. A better controller needed here, to allow the robot performs efficiently and make less error. This project try to implement a PID controller on mobile robot to see whether the robot perform efficiently. This mobile robot has a line tracking module, where it will follow the track that made from black tape. This is area where the PID implemented, the robot will be able to follow the black tape effectively and moving along the track smoothly
