yasakwa kinetic is easiest to "program". If that concept went cobot with ability to lift some weight it would be mainstream. Saving all the 25-150 pound parts for us humans is not so fair. Workers are cheap compared to robots tho. If robots could work in heat and cold it would be nice too, our Panasonic we have to give up personal space heater when it is cold, and when over 95 we have to give up a fan. Same with our big robot processing machines, but they work tons of steel an hour, not the little bit of holding a torch up of the panasonic. Fanucs are smooth, but are really temperamental to clean air, can not work long term in plasma booth without body armor, which tears and is just another con$umable. It is why you do not see them in copers.
