Would someone please create a small car/toy with computer vision that can race around my house so my dog can chase it? I'm serious. Dog owners everywhere would buy one.

Bumping into walls and furniture would be OK if it had decent bumpers.

Upgrade 1: Have it detect the dog and stay away from it.

Upgrade 2: Make it so it can operate in in grass and stay within some boundary, or within X feet of where it started (for yards with no fences).

I think my wife and I would happily spend $200 to keep our puppy entertained and tired (we can't possibly exercise him enough!).
