Talking Re: [FTC]: Can I add non-slip material to 4" Tetrix Wheels?

Thanks Henry! I had forgotten that we could wire two motors to the same controller port. We have the motors and mounts. Lets see if I get it...

Two mirrored assemblies: Left Side Drive & Right Side Drive
Parts list for ONE Assembly:
2 wheels with bearings and axles
2 DC motors and mounts
1/2 Motor Controller
1 Encoder
2 Wheel Gears, one per wheel with axle and hub
2 Motor Gears, one per motor with motor hub
TBD Gears as needed to connect the gears attached to the 2 motors and 2 wheels into one meshed drive train

Wire both the motors onto the SAME Motor Controller Port.
Final gear ratio is determined by wheel gear/motor gear.
Size of intermediate gears does not matter.
Make note that each intermediate gear reverses the direction.

QUESTIONS/ASSUMPTIONS
1.Can we run all four motors off one motor controller, ganging them up two motors per port? We can borrow another motor controller. CAREFUL of the wiring!

2. Is it better to mount the motors closer to the ends near the wheels or put them in the center near each other and drive gears out to the wheels?

3. I'm assuming the fewer intermediate gears the better?

Now I see how you could have the six wheel configurations with the two motor per side. Raise the ends an 1/8, which helps transition the edge... makes much more sense now!

This would be a LOT more fun if we didn't have deadlines LOL
