Quick and funny solderless robots
Here is another version of bristle-bot but this time without heating up the soldering iron. With just two batteries, DC motor, few pieces of wire and brush head you can make a little robot that chaotically moves around.
This is not a very serious device and it has no specific purpose. Anyway, it would be very funny to watch few dozen of these crazy devices moving around and hitting each other in a condemned space.
