Robot arm becomes a robot bartender, your approval rating with friends soars

Dave Zucker

What do you say when someone runs up to tell you that they're throwing away robot arms? If you're Dave Zucker, you'd claim it then hold onto it for about a decade before turning it into a metallic harbinger of intoxication.

In case you were wondering why it took Zucker over ten years to finally produce a robotic bartender that met his expectations, it looks like it had a lot to do with the fact that the appendage he acquired wasn't functioning properly at all. According to Dave's website, the controller had problems turning on, and there was far too little in the way of documentation for the PDP-11-based computer. But once Dave got it working, he was able to complete the booze-serving bot you see above.

The central component in this homebrew automaton is, of course, the PUMA robot arm, one out of a series of robots traditionally used for things like material handling, automated testing, assembly, and even forging.

Aside from the mechanical arm itself, almost everything in Zucker's creation was custom-built out of off-the-shelf components, grit, and brotherly love. Dubbed Sir Mix-A-Lot, the finished product made its debut at Zucker's birthday. And while it appears as though the robot bartender was a hit with his friends, Dave says he still wants to fine-tune his creation further.
