Re: [FTC]: Motor encoders Love'em? or leave'em?

DavisDad,

I have not seen the Matrix motors used so far. For us they seemed too weak for a 1:1 drive train.

We are using the Tetrix motor controllers with our Tetrix motor-encoder combos. We use LabView for programming.

This year the penalties are rather high and easy to get if you plan to use blocking and pushing for a defense strategy. We wanted the more powerful Tetrix motors for better acceleration to peak speed.

The AL welding makes more sense for our team at the FRC level than the FTC level, especially since we have already accumulated a lot of the Tetrix channel and related parts. It does really annoy me though when I see too many screws and nuts falling off the robot, and wiggling joints negatively impacting performance.

Good luck using the VEX square shafts to drive your VEX mechanum wheels.

-Dick Ledford
