Hi Guys, So I have this project that itâ€™s a bit complicated to explain. Imagine that you have a square like in Figure1. There are some small parts that will be moving in this square only. These parts have to be interconnected and they have to build up and move to the top as shown in Figure 2. So there is a test that it has to be done on these small blocks and if one of them falls out there should be another block that has to move automatically and then fills in the gap as shown in Figure3 (Generally fill in the block thatâ€™s missing). I really donâ€™t know anything about mechanical engineering so please donâ€™t judge me. Iâ€™m an Electrical Engineer so please if you have any idea how I could design this thing that would be a life saver. Again any help will be deeply appreciated. Thank you.
