A social experiment in New York, where a small robot is guided using only human interaction to get from one place to another by changing the direction of the bot. The link above contains a few pictures of the bot. Found a nice video over here.
An exposure for 30 minutes of the movement of a roomba. Pretty interesting how it begins in a spiral, then bounces across the room. Though I believe this is probably one of the most inefficient ways of cleaning (does it learn patterns?), it looks pretty neat.
