The big market for robotic manipulators is going to be cleaning toilets and clearing the dishes off dinner tables and placing them in a dishwasher. I'd guess that the domestic market is literally one million times larger than the industrial market. The industrial use of robots is dead-easy. They run on g-code and make precise pre-programmed motions. Clearing dishes is at the other end of the scale of difficulty. But there are intermediate use cases that are not crazy-hard like moving boxes between trucks and warehouses and say picking up trash in a public park. As it turns out, for all the really hard tasks, +/- a quarter-inch (0.25") is accurate enough. You only need 0.001 inches for the simple no-brain jobs. So my point is that you can do a LOT with the cheaper 3D printed plastic version of this robot. I'm surprised there are not more people here working on robots. hey are very much like CNC tools but more interesting. > > > On Tuesday, January 4, 2022, 02:36:42 PM MST, Ralph Stirling < > ralph.stirl...@wallawalla.edu> wrote: > > That AR3 robot is indeed interesting.
