Introduction
Robot
Any robot (with tires or treads, perhaps walking robots too) will work.
Sensors
The ultrasonic (distance) sensor is used.
Example Videos
Theory
The ultrasonic sensor is a sonar radar that works similar to the bats. You should check the performance of the sensor specially if it is not working properly. The maximum working distance is about 2 meters, and the smallest distance is about 10 cm.
Example Code
Exercises
- Ex 1
- Use the ideas shown in previous part (Following a Line) to follow the wall at 10 cm apart.
- Follow a line (previous part) until the robot finds a wall at 10 cm apart from the wall.
- Use ultrasonic sensor to listen if there is other robots using ultrasonic sensors.
