Design and implementation of RGB color line following robot

This paper describes design and implementation of RGB color line following robot. The robot can differentiate among this three colors and according to given instruction it will follow the three different color lane. unlike any other simple line follower robot having the ability to detect the presence of obstacle on its path. The color sensor system is built in using colored LED and LDR as main component. The robot is capable of following very congested curves as it receives the continuous data from the sensors. This robot avoids collision and moreover it can detect collision with obstacle sensor.
