After-school Robots

Wall following

In this competition, the robot has to go down the maze corridors following the left hand wall.
- If there's a wall on the left , it goes straight ahead,
- if there's a gap in the left hand wall it turns left,
- if there's a wall ahead, and to the left, and it can turn right, it does so,
- if it can't,  it turns 180 degrees and comes back again.

The mazes are constructed so that following the above rules will take you to the middle.
