Obviously there's a really good economic incentive to work on labor replacing robots of any kind, so I wouldn't be surprised to see a lot of startups in this space in the next 5-10 years.
I am actually a little bit surprised on why we are not seeing more kitchen robots in restaurants. Ten robots flipping burgers and assembling them and one 18 year old to hit the emergency break every now and then to remove the mustard stain on the depth camera of robot #4. (Actually robot restaurants probably wouldn't have humanoid bots, but look more like an industrial food assembly lines that served the food on plates instead of cartons that get deep frozen at the end.)
