Cad Update (Final) (Sort of)
After an 8-day break, we’re updating this post to let you know that we have almost finished our CAD! We are already 3 days behind schedule, but hopefully, we’ll build it in time.
Let’s start by breaking down each mechanism.
Intake
We have finalized on a Team 95 Style UTB Intake, featuring 2 rollers using 2-inch diameter WCP flex wheels, with 0.5 inch of compression (inspired by Team 3255).
The 4 rollers above are made out of polycarb and will be covered with grip-tape. We couldn’t get cat-tongue grip tape unfortunately as it was out of our budget, so we got a Chinese knock-off from Aliexpress(let’s pray it works)
To center the notes while intaking, we decided to add 3d printed diverters on each side of the intake. We haven’t added them to the CAD yet, but we are thinking of something like what team 3847 is using.
All 6 rollers will be powered by a single NEO motor geared down 1:1.6 .
Dead-axle Arm Pivot
This year we(@Kbeldag ) have decided to design a dead-axle arm pivot after building a live-axle hex arm last year(it did not go well)
This design is very obviously inspired by 2910’s 2023 arm. Huge shoutout to them!
The arm will be powered by a single NEO motor with a total of 1:197.82 reduction. We might end up adding a second motor if one doesn’t suffice, however from our calculations 1 motor should be fast enough.
Shooter (and Indexer)
This design features a top and bottom roller shooter, with 0.5 inch of vertical compression and 2 inches of horizontal compression.
It is heavily inspired by Team 111’s and Team 3255’s shooters.
The bottom plate will be made out of HDPE, we initially thought of making it out of polycarb but after some research on CD we decided HDPE would be better as it is more slippery.
We will be using 8 stealth wheels, 4 being blue and 4 being orange. The shooter will be powered by 2 NEO motors, geared up 1:1.6 . The indexer will be powered by a separate NEO motor.
Climber
We will be using 2 telescopic climbers with a Team 4481 style hook attached to them. They will be powered separately using 2 NEO motors geared down 1:16. We initially wanted to climb using an elevator, but we decided it would add too much unnecessary weight to the robot and decided to challenge ourselves by building telescopic climbers, as it will be our first time building them.
That’s it for today’s update, let us know if you have any feedback or questions!
