PROBLEM DEFINITION To design a light , larg and transportable ACF that will feed and water home cats automatically. It's mass doesn't exceed 8 kg without food. In addition, it has 2.25kg as food storage  capacity and 3.54 liters as water storage capacity.To keep ACF be transportable we made two wheels for it to make that easy.
