Food mixing container
To mix the the food and the water we adapted a plastic 200ml lab flask by drilling three hole on the top part of it and by adding a funnel on the top. The holes are to insert the tubes connected to the pumps, in our ZAF presented here: one for the tube coming from the mixing pump, and two connected to the pumps delivering the food to the tanks. Hole were drill using a Dremel 3000.
We used the small funnel from these kit. The funnel is adapted on the lab shaker flask by inserting the output inside the cap of the flask previously drilled accordingly.
To maintain the tube inside the funnel we placed a tube holder suction clips.
To prevent splashing and possible experimental leak the flask goes inside a water containment tank. We used a magnet anchor to maintain correctly the water container in the robot structure. We glued two magnets on ZAF body and two magnets on the tank (be careful of the magnet orientation!). Same glue used for the servo will work perfectly well.
