Concept: Scaredy Crab

I do not own any lego Mindstorms so I hope this concept can work. The Scaredy crab concept is a crab that always scuttles away from light.

How the concept works: wen a light is on, a light sensor on the crab sends a message to the control panel and the crab moves into a shadow. this could also be modified in to a remote control but I don't know how that would be done.  :)
