The rules state that we must design a new part. Would a modification to an existing part be considered an acceptable part? If so, can we simply modify the existing CAD file rather than recreating the part from scratch?
You must design a new custom part as the rules state. This new part can function as an add-on to existing part(s), working in conjunction with them, but cannot be a modification to an existing part itself. This challenge is centered around designing and modeling a custom part of your own design. You do not have to model the entire robot, just your custom part - so you can use the existing CAD file for components needed to illustrate how your part works/what issue it solves, but you have to create the CAD file for the custom part yourself. Good luck!
