That's a fun video. I haven't seen many "how I did it" walkthroughs like it. Machining the motor pattern into the disk is a great way to get a low-profile high torque transfer connection. I've considered something similar with an outrunner before but the can shape is so seemingly random between them (and even between runs) that I never pursued it. I like the way you built in some potential adjustment for the variation.

This motor pattern was a lot trickier to reproduce than old style. I have to thank Brandon Wiebe for providing the motor model we used for the new weapons. For the old disk I found the motor files on grabcad.com .

Thanks for the build report.

Bummer you didn't do well at Robogames but hopefully you'll do well later this year.
