Re: Encoder with CAN for Drive Train

Can you measure or calculate the ratio of motor input to wheel velocity for the back and front wheels?

If so, you can try to fix it in the SW. After the vector math, the Holonomic VI updates four labeled motors. You can scale the outputs so that the wheel speeds are normalized. I'd make a copy of the VI under a new name. Note that if the ratios are very different, I suspect the nonlinearities in the drive system are going to make this way less satisfying than correcting it with a gear or sprocket change. But since it is a quick SW experiment, I'd give it a try.
