Redesign central differential gear: now it’s strong enough, i won’t buy any metal…
Nice. Has anyone considered eliminating the diffs and associated drive between the axles by giving each wheel it’s own motor? I imagine one of the Arduino multirotor controllers could be adapted to simulate the differential action, and add in some fun stuff like skid steering, traction and stability control, backflip prevention (or trigger), drift control, etc.
after use this diff gear, it never broken, good…
