Tomy has unveiled in Japan tiny toy RC walking robots named Robo-Q. At about 3.4 centimeters (1.3 inches) high and about the size of your thumb these little guys are incredibly small and cute walking robots. Since they can be remotely controlled (see youtube video), they would be great for coffee table robot soccer matches! They also have a few IR sensors and a bit of programming to automatically navigate and solve small mazes. The current release price in Japan is about 3500 yen ($35) each and they should be released in the US soon.
