Looks like I have a solid backup plan if the whole bartender thing doesn’t work out for the robot arm:

But, I still have a good feeling about it becoming a bartender. The latest progress is that following on the success of the prototype bottle gripper (which was wood and though attractive, pretty weak in key areas), I’ve made a permanent one thanks to some friends with… a 3d printer.

Looking forward to attaching it to the wrist and giving it a try…
