This document describes the parts and working of a light following robot. The mechanical parts include a chassis, motors, tires, switch, and battery holder. The technical parts include a breadboard, operational amplifiers, resistors, transistors, sensors, capacitors, and headers. It works by using LDR sensors - if the left sensor detects light it increases the left motor speed to turn right, and vice versa. When both sensors detect light it moves forward. The document then lists other related robotics projects such as line followers, drones, and remote controlled cars.

25. HOW DOES IT WORK?
When your torch light activates the right sensor , it in turn
activates or increases the speed of left motor . If the speed of left
motor is more , it moves towards your right direction.
When your torch light activates the left sensor , it in turn
activates or increases the speed of right motor . If the speed of right
motor is more , it moves towards your left direction.
You can even try it yourself , stand up and only use your left leg
to turn . You will turn right. If you use your left leg to turn . You will
turn right.
When both the sensors detect light , the robot moves forward.
