Red Rover v0.3
The bumper that surrounds the robot is made from a strip of steel from an old windshield wiper blade. The bumper is hooked to the Arduino's electrical ground. When it it runs into something, the bumper rocks back against the paperclip which is screwed to a block of ShapeLock that is stuck to the chassis. The screw is also holding in place the wire that ultimately connects to the Arduino so that it can detect the collision.
