I’ve been working with 3D printers for a while now. Watching them move and print can be mesmerizing. I wanted to make a fun gadget that would demonstrate my skills and create an interactive conversation piece for a party. Hence The BarBot. It’s not a new idea but, I knew I could do it better than most that I’ve seen online and take it a step or two further.
My BarBot features two stepper motors to create linear actuation in two directions; Move the drink from bottle to bottle and dispense the ingredients. I wanted to keep it as simple as possible. Along with the motors there are two end switches to home the motors so they know their positions. I designed and printed all the plastic parts. The horizontal linear actuator is a single steal rail with two rail guides. eBay Link to Steal Rails
I have an Arduino Uno controlling the motors and acting as the I/O controller. From there I have the Uno connected via USB Serial to the Raspberry Pi. Connected to the Raspberry Pi is a 7″ touchscreen and a 1080p Camera with an extended ribbon cable for camera placement.
I am a software and electronic engineer. I work in the field of building automation. I enjoy creating fun, useful and entertaining electronic projects. I love flying RC planes and doing FPV (First Person Vision) flying like I'm in the cockpit.
