I finished doing the remodel with new parts. A lot of it was updating existing parts to fix what I noticed went wrong in the test build, which made V3. A lot of it was improving the clearances and tolerances between parts to reduce friction and increase efficiency. I also made a lot of changes to the software, which is currently uploaded to GitHub. My plans for the future are:Finish making the wheel grippier and make sure the tread doesn’t fall off.Make auto pathing software.Get a full drivetrain ready.
