http://www.elprocus.com/ How To Build a Robot With an Arduino and 8051 Microcontroller How to Build a Robot 1. Robot Body The basic robot body of the robot of obstacle avoidance vehicle.  The robot body is a plastic body and it contains wheels on both sides. Ultrasonic sensor is arranged in front of the robot body. By using the ultrasonic sensor the obstacle can be detected.

The operation of any motor is based on the electromagnetism. The magnetic field is produced by the current carrying conductors When it is placed in an external magnetic field, it will experience a force proportional to the current in the conductor.
