I think its AR Drone delivering sushi at "yo! sushi" restaurant in london
Frightening to think of the injuries that could be caused to the customers.................
My thoughts- Maybe a cheaper segway kind of robot variant(line following) or 3 wheeled preprogrammed robot would be better for such close proximity nonsense, it can be used as the waiters lower body, maybe stabilize the food on a gimbal... ;)
Other better uses for multirotors can be search and rescue, security, perimeter watchdog, first aid, supply drops, and much more sensible areas other than the usual AP. :)
that parrot drone wont lift anything heavier, heavy things= more thrust= more air turbulence= food and other stuffs around starts flying too. ;D
