[FTC]: Mecanum Wheels Axles & Hubs

[F Elliott]

As part of our off season, we are hoping to investigate holonomic drive using mecanum wheels for our FTC robot.

1. It appears there are 4" mecanum wheels from VEX and AndyMark. Which do you prefer and why? Are there others that are better?

2. It seems either wheel design comes with its own set of issues when mounting the wheels onto hubs and axles that can then be mounted on TETRIX channel. Which is the most reliable/durable approach? Which requires the least machining and customization?

3. What "parts list" should we start with if we go with the VEX wheels? What would be the list for AndyMark wheels? Obviously, we want to stay FTC legal.

THANKS!
