To make this project we need a lot of 3D printed parts and a few more components but a lot of manual work. The electronics list is very small, the rest are just plastic parts, screws, glue, ect. See the full part list below with what I've used. The battery I'ver used was 7.4V but is better a 11.1V one. We must use an Arduino MEGA becuse it has more pins and memory. The STL files are ready to be printed and need no support.
