OBSTACLE AVOIDING ROBOT

This is an obstacle avoiding robot which can find its own path despite of having obstacles in its way. Here we have used an IR sensor which acts as the electronic eye for the robot. Whenever the IR sensor detects a threshold value, it executes a pre-programmed routine which allows it avoid the obstacles. 

In this particular robot model we have used a single IR sensor, but more IR sensors can also be incorporated as per requirement with minor changes in the code. For more robustness and precision however, an ultrasonic sensor is suggested.
