The only part of this robot I'm skeptical of is the "grind-on-demand" portion. As someone who regularly grinds my own chuck to make hamburgers, I've learned that in order to get a consistent, even mix between fat and meat, it's absolutely critical to grind the entire roast (actually it's ground twice), and then mix to evenly distribute things. If this were truly grind-on-demand, it would be quite hard to guarantee a consistent product (which is a hallmark of most fast food restaurants).
