We designed a cable car-liked device to simulate the situation of food (pills) entering human body. By the environment it has to stays like mouth, stomach, i ntestinal tract, and how long it will stay, we ensure that our pills will be released only in intestinal tract rather than break down in inappropriate position (Too early or too late). What’s more, this device is not only designed for our project, it can be used to test any other kind of pills easily with simply changing the substance in the liquid and the operating time of the cable car.

Figure 1 Liquid container

We make Acrylic Sheet a box and a cover with holes. The container is separated into three sections── neutral(mouth), Acid(stomach), and Alkaline(intestinal tract). The holes on the cover are to avoid the liquid inside splitting out, but the size of them are designed to let a pill get through exactly.

Figure 2 NXT Lego track device

We chose NXT Lego to build the cable car track above because of its simplicity and creative. Put the cable car-liked device on the cover and start the program.Soaking the pills in the liquid orderly, and decide how long we soak the pills according to the time food stays in the Digestive tract.
