The behavior of yamamo2′s “Self-Propelled Toy Car” is eerily reminiscent of rodent navigating a maze -

Like a beastie, this car is able to run on its own. I made by applying studying of chaos, complex system and neural network. The character of this car is very simple electric circuit. I only used PIC, three distance measuring sensors and two FET modules. I want to commercialize this!! So please contact me(picnome[at]tkrworks.net) if you’re interested in.

Now all it needs is some digital cheese to track down. More project info available on his blog.
