I think that there is a certain percentage of the market where it makes sense to have robots on sight, if their volume is great enough. There is also a certain percentage where they're so small it would just never make sense, at a cost, to have one on sight. I do think that there in the future, we have dreams of packaging this up really small volume, where it's less expensive and more flexible. And knowing what you know about robotics, here's the question i like to ask smart people: Which will come first for commercial use?
