Yeah I was thinking the same thing. While robots can technically be directly remote controlled, generally that definition is limited to using remote control to perform a task. I'm not sure that firing ping pong balls fits into at least my definition of "performing a task".
Maybe the definition is changing as a result of robots moving from industrial to consumer. Perhaps a "toy robot" as this thing is described can just be any controllable moving machine that does anything more than just move about (like RC cars/helicopters do).
