The technology behind the Wii-controlled robot remotely brushing a cat is fascinating, but let's hope for the cat's sake it's not the future. I'm not sure most cats would take to this brave new world.
I suppose if you're on vacation, you could virtually brush your cat and talk to him--unless he freaks out and hides under the sofa! Although the gorgeous kitty in the video seemed to enjoy it for a little bit, until the robot bonked him on the head.
However I can envision many possibilities for the NAO-bot and it's hacked version. The following video demonstrates what else the NAO-bot can do. Watch the robot showing off its Michael Jackson moves.
