In this work the design of a Line Following Robot which is commonly used to carry children through shopping malls entertainment place is discussed as a new commercial product in this field. The robot has five different speed levels, and is able to follow 4.8cm wide black line carrying nominally 400kg load. The robot can be operated in two control mode; Line Following Mode and Service Mode. In the Line-Following Mode it follows the path of the black line in a suitable ground, while in the Manual Mode, it can be moved manually forwards. backwards, left and right free from the black lined path by a remote controller. Robot is operated using two permanent magnet DC motors on left and right sides. Forward and backward movement, or left and right side motors are controlled by two II-Bridge circuits. The batteries can be charged by AC supply from an external source or by DC supply from a solar panel.
