Re: [FTC]: Can I add non-slip material to 4" Tetrix Wheels?
1. You can run all four motors off one motor controller. My team did it every year we were in competition and worked great. However make sure you get the polarity correct depending on how your gearing is setup.
2. Doesn't matter. Preferably minimal transition gears to reduce slop but the slop is very little to minimal. Think of motor placement more in terms of how you want the weight distributed around the robot.
3. Yes - to reduce slop between all the wheels and to save money. However again in the grand scheme of things, it doesn't matter much if at all.
