This video is from a failed kickstarter for "Evezor". It is/was an open source robotic arm that took a variety of different end effectors to 3d print, engrave, draw, foam cut, pick-and-place, and a bunch of other things. They didn't reach their goal for mass production, but I think the inventor still sells them. Being open source, the "source code" including models and plans for all the parts to build it as well as the software to run it are freely available.
Here it is milling wood:
Tapping a bazillion holes:
Drilling a bunch of Acrylic tubes:
... this would have been a lot better if the arbors on the rotary axis had been tapered to center the tubes. Maybe that was part of the spec?
As a vinyl cutter:
(I'm surprised this worked. Exposed electronics and stepper drivers get fidgety around welders in my experience.)
