I'm frankly not very impressed. There is too much human interaction woven around the automated functions. I have to think a little creativity with the technology for conveyor broilers (think Quiznos) and automated pick-and-place (the way printed circuit boards are assembled for solder flowing). I don't see any reason why a human couldn't load raw materials into the machine and take completely finished burgers off the other end for plating or wrapping. The $60-100k price point would be hard to match but I think $150k might be achievable with small volumes.
