A DIY robot that makes mixed drinks. Four 12V peristaltic pumps are controlled by an Arduino through a relay module. A control panel on the front allows the user to tweak the ingredient levels (+/- %50). As the drink is powered an agitator shakes the cup to help stir the fluids. The project is housed in a laser cut acrylic case was design with MakerCase (en.makercase.com) and cut on a Boss Laser. All the grey parts were designed in Fusion 360 and printed on a MK3S Prusa 3D printer.
