OK, sounds promising. I assume the market will be small, but that would depend on the price as well.
You could do things like make the ROB run from a battery eliminator, sitting up on a shelf with his glasses on, (powered from same source would be cool) 24x7. Then pull out your phone and have him turn towards guests or something.
OOOOHHHH, even better, I got it! "Alexa, tell ROB to open arms"
