Robot bartenders are nothing new. We have covered a few sophisticated ones in the past. Would you like to build your own? RobotGeek has the instructions to help you get started. This particular robot arm bartender is powered by Arduino. You are going to need a RobotGeek Pumping Station, Snapper Arm, Spout Kit, Mega Workbench, and a few other parts to get started.
The above GIF shows this robotic bartender in action. Of course, you can always add additional sensors and modules to build more sophisticated versions. More information is available on Instructables.
