Introduction:

An obstacle avoiding robot is an intelligent device, which can automatically sense and overcome obstacles on its path. It is developed without micro-controller in order to eliminate critical circuits, difficult programming etc. All you want to do is to just understand the circuit diagram and start doing this robot. This simple technique can be incorporated in wheeled robots to keep them away from damages and accidents.

What’s required?

This intelligent robot requires several components to bring them alive. It doesn’t cost too much, and easily available in all electronics markets as well.

2 x 12 V DC motor
2 x IR Sensor modules
1 x IC 7404
1 x IC 7805
1 x IC L293D
1 x Breadboard
2 x 10 uf capacitors
2 x Plastic wheels
1 x Castor wheel
1 x Battery (requires according to the usage)
1 x Battery holder
1 x Battery snap
2 meters of Breadboard wires
1 meter of Two-core wires
2 x 2 feet cardboard (for preparing the body of robot)
