Line following is the technology that is used for moving a robotic vehicle to a specific place, without any interference of direct human control. this technology is mainly used to move goods buggies in any workplace of an organization. but it is not actually practically much preferred concept as path of these robots may have to be changed. but if the path is not physical, or say imaginary, the drawback of previous version can be overcome. this is the main concept of this project: “virtual line follower”. this is done by making that line virtual, means the line should be present in the robot’s memory. so that it can be changed anytime with an ease. with a user friendly graphical user interface, the administrator can define path in computer’s memory and the robot can follow that accordingly. and if the path has to be changed, it can be easily changed just by changing path in the computer. this robot follows a line which is virtual, hence the name “virtual line follower”. this novel way of controlling the robot is disclosed here.
