Some basic robotsLine follower Problem Statement: Robot has to move on black line on a

white surface Principle: white colour reflects light

black colour absorbs light. 1. Electronic part 2. Mechanical part According to this principle if there are two wheels in a vehicle

and 1 moves forward &other moves back ward then the vehicle turns left or right as:-

CASE1:- if the right wheels moves clockwise and the left wheel moves anticlockwise then it will turn left.

CASE2:-if the left wheel moves clockwise and right wheel moves anticlockwise then vehicle will turns right.
