Path Follower Robot Project Based Workshop | NevonProjects A path follower robot is a robot which follows a certain path controlled by a feedback mechanism. This project consists of a robotic vehicle to follow a desired path. Such line follower robot is used in various workshops, factories and many more places, where unmanned vehicles are used to follow a specific path without using tracks. Line Follower Robot - engineersgarage Line follower is an autonomous robot which follows either black line in white are or white line in black area. Robot must be able to detect particular line and keep following it. For special situations such as cross overs where robot can have more than one path which can be followed, predefined path must be followed by the robot.
