How to make Edge Detecting Robot || Edge avoidance robot that never falls off the table !!!

Hello friends,
In todays video, we will learn how to make an edge detecting or edge avoidance robot. This robot detects the edges of table and avoids falling down. The project is done using arduino uno and ultrasonic sensor HR- SR04 as the main components.

The edge detection is done using the 2 ultrasonic sensors. When both the sensors are on the top of table, the robot continues to move forward. When at least one sensor is outside the table, the robot takes a reverse and changes direction. The response time of the ardino and ultrasonic sensor is very less and edge detection is done very quickly by the ultrasonic sensor.
