Robot

Objective of the Robot

The robot was designed to follow a metallic tape stuck to the floor. At the discontinuities the robot had to find the tape again and at "T-points" in the tape it had to stopped before continuing. It also had to drive a perfect arc and along a straight line without the aid of the metal detectors. This task formed a good test for testing the accuracy of the software motor controller.

Robot Features and Hardware

  • Two metal detectors for following the metal tape.
  • Proximity sensor to prevent it driving into walls.
  • Remote control for controlling the robot remotely.
  • LCD display for displaying statistics and debugging the robot
