Abstract

Line following robot had been used in many applications such as moving materials around a manufacturing facility or warehouse. Line following robot is designed for a mobile robot to detect and follow the line. The line or track is a black line on the white surface and it will be detected by sensors. The project objectives are to design high speed line following robot in term of hardware and software that could take a curvy track turn without leaving the line or track and would be able to correct the error itself if leave the line or track. The project also design and implement proportional, integral and differential control as the error component in the line follower robot. For this project, the robot would have a high speed movement and be able to take a sharp turn without leaving the track or path. If the robot leaves the track or path, the robot would be able to find the way to be back on the right track again. In other word, the robot would be navigate efficiently, make less error and be able to correct the error itself. In order to have effective and smooth navigation, the robot had been implemented with PID controller. From analysis, the line follower robot that had been designed was able to detect and follow the line in higher speed. By using different speed, the line fo lower robot able to move forward, turn right and left and able to correct the error itself. For future research, the auto tuning for proportional, integral and derivative constant can be developed.
