What advantage does this have over a remote control helicopter + light + camera + wifi? I bet you could package that for $50. Ok, so you need to practise a bit to learn how to control it, and if it's out of sight that'll be a bit more difficult than it is usually.
I'm skeptical that a stationary ball lying on the floor (or rolling into a hole) would provide better information. Of course, it's better than not having that.
