Abstract
This paper introduces a Robot having the ability to choose a desired line among multiple coloured lines. Every line has different colors as their identities. The robot can differentiate among various colours and choose a desired one to find its target. Unlike any other simple line follower robot, this robot can be considered as a true autonomous line follower robot having the ability to detect presence of obstacle on its path. From the android mobile, instructions are given to the robot that senses a line and endeavours itself accordingly towards the desired target by correcting the wrong moves using a simple feedback mechanism but yet very effective closed loop system. 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.
