DESIGN AND IMPLEMENTATION OF DOUBLE LINE FOLLOWER ROBOT

摘要

This paper presents design and implementation of line follower mobile robot. It operates as the name specifies. It is programmed to follow a dark line on the white background and detect turns (or) deviations and modify the motors appropriately. The path is sensed by the IR (Infra Red) sensors. Differential steering is used to turn the robot. In this system each back wheel has a dedicated motor while the front wheel is free to rotate. The microcontroller controls two DC motors of robot to navigate through its path. The mechanical constructional design and circuitry interfacing with microcontroller of robot are presented. Several running tests are made on the robot to verify the capability to follow the line by choosing the correct path and achieve the goal position.
