Go to Post I was dragged to the first team meeting in September my freshman year and a week later, found myself at Fall Classic. Needless to say, after experiencing the heat of a competition, I was in love. ... Robotics has become far more than just that. I get to do the coolest thing in the world. - Audrey Chu [more]

Eh... I was complaining about the designs too. Too much focus on flash and pocketing, not enough focus on functionality and practicality.

Good design is focusing on eliminating items before pocketing them. Design for manufacture is key.

I didn't comment as I've learned to avoid (or try to...) providing criticism to people in that stage, as they generally don't listen to it anyway.

It doesn't look like you have any sensor feedback on the wheel (velocity, you have a thing for angle i think). Do you have something planned for that? This seems like a cool application for that on-CIM encoder that's been going around CD these days.
The power transfer is still technically Coax, just pseudo planetary coax...

The module support is a 1/4" section silverthin bearing, the forks that hold the main wheel dead axle overlap the inner race of the bearing and clamp it. This is what handles the weight of the robot. No more custom bearing 16 style stuff, just a big COTS X-contact awesome bearing.

And that was my first thought after seeing that nifty CIM-encoder setup Chris, it'd work quite well as I currently have to cut the CIM shaft anyway.

This is by far the "most legitimate" swerve I have designed, and no pocketing etc has been done, I am confident it would last through a season and then some, while still being easy to work on.
Fun Fact, it only has 1 nut on it, and I could remove that one as well if I really wanted to. (Wheel dead axle)
