Robotic Bartender

This is a low cost, low power bar robot project. There are many here on Thingiverse already but these require air compressors, mains voltages and have Bill of Materials that run into the hundreds of £'s or $'s.

This design has most of it's parts 3D printed. Is designed to run from a USB battery pack and some AA batteries. (Keeps the power levels safe which is important when working with liquids and allows you to take the machine to parties, the garden or beaches with relative ease).

If you make your own one I would love to see it. :)
