Follows line

Nothing much to describe about this robot.Its a simple line follower robot which uses 2 ldrs

and 2 leds as a sensor to follow line.

The robot is powered using two battery packs i.e. 9V battery for arduino and all other components and 6V battery for motors.

 Chassis made of acrylic

This is  the sensor which detects line.I will soon replace it with infrared transmitter and reciever for accurate line following.
