Hector 9000

Description

The idea was to build a barbot which is able to dispense 12 different liquids. We did not want to use peristaltic pumps, because it should be possible to dispense carbonated drinks. So we decided to pump the liquds with pressured air. The mass of the dispensed liquids are measured by a load cell. By using pressured air there is some loss of carbondioxide, but the Cocktails are still fizzy.
Beside the dispensing function we included some eyecandys like some (needless) moving parts and blinky LEDs.
To control the barbot we choose a Raspberry Pi. You can choose the desired Cocktail on a 7" touchsreen. After mixing the drink Hector gives an acoustic signal.

Details

One of our focal points for the development of Hector 9000 is, to make it as easy as possible to replicate the machine. Thus we

used of the shelf & easy to source electronic components
made the mechanical hardware parts mainly by FDM printing (without support)
host the software on GitHub
try to make a good documentation

We also made most of the functional parts independent from the structural parts to give a high degree of freedom for an individual case/cabinet design.

During the work on Hector 9000 we had a lot of ideas for additional features and improvements. Here are some of them:

Ice dispensing unit

Cocktail Umbrella dispensing unit

Dispenser for sugar

GUI based on Qt

Statistic functions (Best Drink of the Day, ...)

AI to create new Coctail recipes

Due to better maintenance and collaboration, we transfered the CAD files, the software and the Documentation to GitHub.
We will also provide the STEP files for the 3D printed parts in the near future.
You will find the files in the following Repositories:

Fixed .stl-file

We fixed a wrong positioned hole in the .stl-file for the valve body.
CAD Bug

Some of you mentioned that there is a bug in one of our CAD files. It seems that at least one hole for mounting the servo into the valve body is not positioned correctly. I will fix it within the next week. We have to apologize for the inconvenience.

EZ-to-assemble™ Cam
Cadmium • 02/07/2019 at 19:58 • 1 comment

We got some feedback from people which are building their own Hector 9000.
Thank you very much for the feedback!
Some of you pointed out that it is very much work to assemble the valves, because it is neccessary to customize the diameter of the original servo horns. So we tried to create a cam which you could directly mount to the servo shaft.
Because it is nearly impossible to print the splines of the servo shaft with an ordinary FDM printer, we think it could be possible to press a cam directly onto the shaft and secure it with a M3 bolt. We propose to use PETG or ABS for the print.
Unfortunately our printer is down for maintenance so we could not test the design. If you decide to try the new cam, it would be nice to get some feedback. You will find the .stl file for the cam in the download area as a single file (not included in the stl archive).
