4wd with belts is hard.

I think most if not all of the time here was spent working on trying to get 4wd to work.

• The first belt I tried had gear teeth as the belt tooth and they did not mesh around the turn, as well as being way to small.
• The second one had self-designed timing belt teeth on it (following a tutorial) and it still did not mesh.
• Then I changed the design and it didn’t fit again, but the new belt and the old pulley DID mesh!
• So then I had a belt that did mesh but was too tight; I could barely get it on and the motors didn’t turn when the belt was on.
• Then I made it larger and it turned only when going fast, but not slow.
• After that, I asked in the combat-robotics Slack channel and got an idea to cut out milk jug caps for friction reducing washers. That made it work when going slow but not when going fast. (Yes, this is opposite of what it did before.)

My conclusion is that the regular bolts make too much friction and when the shoulder bolts get here (AFTER the tournament) hopefully the belts will work. Sigh.
