And as far as that goes, I'm thinking old pogo sticks might come in handy. If you took a giant ball with spikes like that, and tensioned a large weight in the center correctly, you could make a self-cleaning ball that would crawl over objects! (by self-cleaning, I mean the spikes would retract when they near the top of the ball, and thus scrape off any debris they may have picked up)
