Howdy everyone! Because many of us now have some time on our hands, I figured now would be a good time to talk about CAD. What cool CAD things have you or your team been working on? Personal projects? Tips?
I also think it would be cool if we came up with a few random topics (hats, logos, weird shapes, etc.), make something, and then come back here and share what we made, like a weekly thing.

Variable derived swerve drive chassis with two different modules (WCP and SDS), in case my team wants to explore that in the upcoming eight months. (Swerve would be awesome!)
And a custom sprocket featurescript to make any size sprocket (up to like 400 teeth or something stupid) for both #25 and #35 is in the works. If anyone knows how to circular pattern in a featurescript HMU. Mechanical person doing coding means I don’t really know what I’m doing.
edit: thank you @marcusbernstein for the help getting the circular pattern working. I will probably release a version of the featurescript in the coming weeks.
Also looking to do a variable driven telescoping arm in the near future or maybe just a variable driven elevator. And once our shop gets opened up probably a spindexer.
CVT WCD. Something to try in this extensive off-season…

Designed a prototype mini swerve chassis, redesigned my mini FTC mecanum in a few different flavors of COTS, designed yet another WCD, this time using some of the newer products that came out this year.
Depending how long this goes, I might take a spin at a new IR robot.
Personally don’t like designing much other than robot things, but I’d encourage you to try doing a CAD/discussion series. You might find a good group for that.
Working on designing a 3 stage rocket rn and after thats done I’m gonna work on FRC stuff like a WCD, elevator, etc.
Working on an octocanum drive train, along with something ridiculous to put on it. Maybe a hatch panel launcher…
Additionally trying to get as many teammates to do cad as possible, if anyone has tips on how to do that that would be wonderful.
Designing a custom 3D printer and then want to get back into some FRC related stuff.

I’ve been cadding robots for a lot of past games so that hopefully next build season we can get CAD done even faster and to make sure I know how to handle some of the game elements I haven’t personally experienced in season before.
It’s great that you’re trying to get others to CAD! If you’re open to using Onshape, I know they have the Onshape learning center with a bunch of helpful tutorials. A lot of times my peers get frustrated with CAD because it’s outside their comfort zone, so definitely take your time, teach patience, and make it known that it’s okay not to understand at first (because that’s why you’re teaching them!).

CVT?
Continuously Variable Transmission. Basically allows you to change through a range of gear ratios. This video is a good example of the technology.
Previously in FRC, team 1640 Sab-BOT-age has used it on their swerve modules. Their 2020 module release can be found here.
our robot only exists as auto auto cad drawing so I’m currently 3D modeling it
Been working on switching to Onshape for better accessibility, so yes I will definitely check out the learning center and send some of that over to team members. Thanks for the input!
I was trying to design a CVT gearbox that would interface nicely with the KoP chassis.
All the things! But mostly little cable organizers and custom clips to tidy up my desk wiring. Ya know, the super low priority stuff because I’m procrastinating online classes.

I’ve been practicing my CAD abilities with solidworks model mania.

Designed a simple chasis to test mk2 modules last night. Next I want to design some drive modules for a beetle weight battle bot
