Given the specific project requirements, our team came up with the idea to make an automated water dispenser which would be able to determine when a cup of any size is full. To do this we had to answer several questions regarding what the design would actually look like, how the cups would be filled, the speed at which they would be filled, the amount of components that would be needed, etc. By asking ourselves these kinds of questions, it allowed us to have a clearer idea regarding what approach should be taken to complete this project successfully. Once these and some other questions were answered, we started creating rough sketches of our design on paper, to figure out a rough estimate of the electrical and mechanical components which would be necessary. After finalizing the sketch we began doing research on the components needed for this water dispenser to function. This consisted of sizing the motor, designing a power interface, and identifying what sized pump we needed. With all the details figured out we began to order the parts necessary to begin building the dispenser. We also designed a 3D model of the body of the dispenser, because our original intentions were to 3D print the dispenser.
