Food mixing container
To mix the the food and the water we adapted a plastic 200 ml lab flask by drilling three holes on the top and added a funnel. The purpose is to insert the tubes connected to the pump: one for the tube coming from the mixing pump, and two connected to the pumps delivering the food to the tanks. Holes were drilled using a Dremel 3000.
We used the small funnel from this kit. The funnel is adapted on the lab shaker flask by inserting the output inside the cap of the aforementioned previously drilled flask. To maintain the tube inside the funnel we placed a tube holder suction clips.
To prevent splashing and mitigate accidental leaks, the flask goes inside a water containment tank. We used a magnet anchor to maintain correctly the water container within the robot's frame. We glued two magnets on ZAF body and two magnets on the tank (be careful with the magnet's orientation!). Same glue used for the servo will work perfectly.
