Design and Fabrication of Line Follower Robot

Abstract

Line follower robot is a robo car that can follow a path. The path can be visible like a black line on the white surface (or vice-verse). It is an integrated design from the knowledge of Mechanical, Electrical and Computer engineering. This paper presents a 700gm weight of a 9W LDR sensor based line follower robot design and fabrication procedure which always directs along the black mark on the white surface. The electromechanical robot dimension is cubic inches with a cost of BDT 1150. This low cost fundamental electronic component based line sensing robot can carry a load of about 500gm without getting off the line.
