The things you folks can do with a 3d printer are truly inspiring! Thanks for releasing this.
What was the value of having the note ejector be able to engage and disengage from the shooter pivot? Why not have it always āactive?ā

there were some (e.g. @Korny 
) that wanted it always active.
there are 2 reasons for making it āengageableā:
1- 99% of the time (in CMP it was 100%) - the robot does not need it - and minimizing the amount of moving things in a very small and dense robot is beneficial and more reliable.
2 - it is a super cool mechanism - to engage the ejector live when needed. and being cool is an important factor in the decisions for this robot

Do you have a video demonstration?

Hi, I was Wondering how the treads in your swerve are held in place?
I see you have a hole where the treads are inserted into the wheel, but how are they held there and remain tight?
Thanks in advance!

Itās been the same design since then. We found methods to make it quicker and our pit crew is fairly skilled at it

hi, i have heard that in your alpha bot you tried diff shooter and didnt like it. could you send some photos of this shooter?
Hey! I am developing a game and I was wondering if I could put your robot CAD in it?

We were inspired by 254 to try different wheel configurations to get the note to spin, including removing parts of some wheels, removing one side of the wheels altogether, and more configs. We didnāt feel like designing the shooter from scratch to have different RPMs was worth it, so we limited ourselves to try and adapt our existing shooter. Maybe itās the side compression or something with the wheel configs (diameter, distance), but we couldnāt get it to add enough spin to shoot any better than our standard shooter.
This is one of the configurations we tested:
In this test you can see the notes still tumble mid flight, and our overall long range shooting accuracy didnāt improve

Hi, Iām working on a vision system for my team. Iām curious about the camera you use for object detection and AprilTag detection.

They are there likely to strengthen 3D printed parts.

did you guys fabricate your own bevel for your intake ākickerā wheels or is that off the shelf? didnāt look standard to me
i know why its there, i just mean is it really needed? we did a similar thing but connected the pla part straight to hex and it worked perfectly fine
Most likely for security. With the insert they wonāt have to worry about the hex rounding out (which happened a lot in our robot this year).

No it is not needed in every situation.
In my experience it is a good idea on pulleys and printed gears that experience higher torque loads at the shaft. 3D printed 5mm HTD pulleys more likely to strip the hex profile than round the belt teeth from my experience.
Iām sure there are ways to optimize print settings and material choices to avoid these potential problems, but safety factor is always a nice thing to have.

really love the look of those LED strips do you guys have the name of the product or the suppllier

And backlash sensitive mechanisms. Metal on 3DP even on low loads wears out fast enough that you end up getting really bad backlash pretty fast.
