Starting in 2017 I did some work for the robot lab of the RWU.
There I got to know cocktail machines and later took part in [drinkrobotics](http://drinkrobotics.de/), where I did some work on our proper, big, cocktail machine Ubabot, [as seen on Hackaday / CCCamp2019](https://web.archive.org/web/20201108013437/https://hackaday.com/2019/08/22/ubabot-mixes-up-50-cocktails-to-quench-cccamp-thirst/).
It originally used relais to power the pumps, but we had a motor driver PCB that we wanted to use instead, [so I wrote a Firmware for it](https://github.com/drinkrobotics/avr_pump_board).
We got an award for this machine at Makerfaire Friedrichshafen, presented it at Makerfaire Hannover, visited the [Verschwörhaus Ulm](https://verschwoerhaus.de/) and various other events over the years.

### CCCamp2023

Of course we also visited the CCCamp in 2023.

### MCH2022

Here are some photos of our tent at the MCH2022 summer hacker camp in the Netherlands.

We also developed an app for the MCH2022 Badge that can be used to login to the machine.
The app source code can be found on [GitHub](https://github.com/drinkrobotics/ubabot-mch2022) and in the [MCH2022 Badge Hatchery](https://mch2022.badge.team/projects/ubabot).

### CCCamp2019

Here are some photos and videos of our tent at the CCCamp2019 summer hacker camp near Berlin.

### Makerfaire Friedrichshafen

In 2017, we rebuilt Ubabot as part of the Maker Challenge of the Makerfaire Friedrichshafen.

[A video of our machine in action can be found on heise online](https://www.heise.de/make/meldung/Maker-Faire-Bodensee-2017-Cocktails-Cosplay-und-Casemodding-3772515.html#nav_im_wettbewerb_0) (scroll down).

### Stuff

I designed a 3D model for a cap enclosing the large open glass bottles we have for some ingredients.
It is a 2-color model that can be printed with a dual-nozzle printer, or you can just leave out the "filling" and print it with a single-nozzle printer.
The design [can be found in my Git Repo](https://codeberg.org/xythobuz/3d-print-designs/src/branch/master/cocktail-maschine).
