Jonny's buggy was a late addition to the project, and is designed to be a moving target for the sentry robot. It is designed to bumble around the sentry robot semi-aimlessly.
How it Works
Initially the buggy spins around and waits for its single infrared sensor to 'see' an object. If it sees an object, it will drive towards it until it bumps into it. The three micro-switches on the bumpers instruct the buggy to reverse then turn in the appropriate direction once a bump has occurred. If the buggy doesn't see anything after turning for a while, it drives in a straight line for a while, then the process repeats itself.
