So how to determine if the robot has actually hit something? After playing around with dead reckoning navigation using the encoders this was the next task to resolve. I figure you need mechanical bumpers of some sort. It needed to know if it hit a wall on the left or right corner or if it was a direct or nearly direct hit. A soft foam surface would probably be required to be glued on the bumper to prevent damage to walls.

This is a close up of the mechanism made out of a bolt and spring and the bumper out of kiln dried wood.

Here is a view of the whole robot base hitting a wall at an angle. I tipped the base upside down in one image to show the mechanisms.

Here is a view of the whole robot base hitting a wall directly (Both switches on).
