The theme of today is building a robot hand model, which is a more complex application of the pneumatic system. In this section, the pneumatic robot hand consists pneumatic components from cylinders and pumps to the air valve, the air tank, and the manometer. With the built model, the students got a deeper understanding of the design philosophy and working principles of the pneumatic system, which built a solid ground for the next following even more advanced pneumatic robot arm model. The STEM information behind this section is the application of pneumatic systems as well as the cylinder piston rod force output calculation, which can be calculated by multiplying the air pressure with the piston area. All the students finished the model and the experiments. And they conducted the objects grabbing with a lot of interests and fun.
