ZAF Plus Frame
Similarly to ZAF, you will need a Makerbeam starter kit. However, we recommend that you buy more Makerbeam kits since the ZAF+ structure is more elaborate and needs to support more components. Of course, any similar prototyping beam-based system could work too, and we welcome suggestions for alternatives. For the model presented herein you will need two packs of 200mm, two packs of 300mm and a bag of corner cubes. Of course, this list is not exhaustive and can be readily adapted to your specific design needs. Do not hesitate to navigate on the Makerbeam website (or alternative) to find the ideal components for your ZAF+ project.
The ZAF+ frame is divided into four modules that can be attached together, each responsible for a different function during automated feeding:
- Raspberry Pi computer and touch screen.
- Electronics for motor and valve control.
- Valves and tubing assembly.
- Food preparation and pumps.
There are many different ways for you to build ZAF+ using the Makerbeam components. In any case, the design must integrate the four modules described above. We apply the same principal as for ZAF: the structure must be solid and integrate in its original design the location of the different components (e.g valves, pumps, water manifold, etc...). Check out the ZAF frame page for some examples, such as structure reinforcement with steel brackets and also how we built electronics support using Makerbeam accessories. To optimize the space and the ergonomics of ZAF+, we directly drilled in the 20mm beams to be able to use screws at any position along the beam. We used the drilled holes to fix the valves and the manifold on the Makerbeam 200mm and to attach the pumps tightly to the structure.
