Every year, we find a thread like this, and everyone shares something that their most proud of. And as a mentor I find these threads inspiring.

Am I missing something, or do we not have a similar build thread just as inspiring? Have we figured out all the main forms of mechanisms that there’s nothing new under the sun?
If not, tell me, what are you proud of that you accomplished in build this year?
I am super proud that we built a 90% machine made robot this year, and almost on time at that!
programming actually has a robot and we might have drive practice for once
That… Is… Huge, I feel like it’s a struggle for us too! There’s always one more iteration needed, isn’t there?!
A elevator built so it can act as an indexer as well
We have a working climber for the first time before competition. We normally test it Friday or Saturday at competition
What?! Pics?
Here is a decent picture. Basically I gets fed by the intake but then can get manipulated by the elevator
Ignore the hooks, old picture.
So do you actuate your climber to bring the cargo up way to efficiently use your space!
Yep!
A team.
Love our teams custom belts
Not about a specific assembly, but we’ve designed and built (rather, almost finished) a robot with a very young team. The vast majority of our team are in 7th, 8th, or 9th grade, and ~60% of the team is new to the program this year.
I’m proud of what we’ve accomplished so far and look forward to the weeks ahead.
One of my favorite things we designed for our 2022 robot is our climber pivots. We decided early on to try for traversal climb and really liked the pivoting telescoping systems used by teams for the 2013 game.
Building on what we learned from the 2019 on how not to build a high torque pivot, we decided our 2022 climber pivots needed to be robust, that hex shaft wasn’t ideal, and that dead axel was the way to go.
With that in mind, this is what we came up with:

Some design details:
Custom as in 3d printed?
Something new we tried out is adding upper magnetic limit switches at the top end of our telescoping climbers since we didn’t want to rely on the NEO encoder because the spool can and does sometimes wrap unreliably.
To do this we machined the Derlin TTB 1.5"x1.5" end caps and embedded a magnet. We then mounted the REV Magnetic Limit switches to a 3D printed collar that fit around the outer 2"x2" tube. This setup allows us to adjust the limit switch location on the fly because we figured out the switch can sense the magnet through the 1/16" aluminum.
Intake and programming…this after several less than good intakes, appreciate the progammers
