CAD Finished!

Our CAD is now finalized for our robot Whiteout! So feel free to ask questions about it.

Onshape

[Eaglegrant]

The Onshape is saying the access is denied. Also, I LOVE that intake design! Very innovative, and the way you showed the process, not just an overview, is very for me trying to understand it! Thank you

link should work now. I was able to view it without signing in.

Hello, my team and I loved your design, and we also have a question, What was the gear jump you used on the arm to score on the amp?

[1712ControlSystemGuy]

not sure which gear you are referring to so I’ll list all the gear ratios

arm pivot: 36:1 from planetary + 4:1 from belt, 144:1 total, 2 NEOs

arm intake: 5:1 on NEO

arm eject: 20:1 on NEO 550

climb: 100:1 winch

Did you guys use a dead axle or a live axle?

[1712ControlSystemGuy]

We used a dead axle. The pulleys connected directly to the arm with 4 bolts each

[Lil_Lavery]

I know I taught you the difference between an axle and an axel

[Michael175]

Do you have a bill of materials for easy access?

[1712ControlSystemGuy]

We have our BOM for the entire season, but we don’t have one for exactly on the robot. It was made with a lot of Rev Max extrusion and other rev ion parts, along with some black anodized T-slot. Here is the BOM for the season.

[Bigbraintime303]

What is the starting configuration of the robot and can the robot start with a part of the robot outside bumpers.

[1712ControlSystemGuy]

It cannot. The robot starts with the arm up. We can achieve this by setting the arm to coast, raising it, and then setting it to break.

Hey! What angle is the robot arm at when it is in shooting position?

[PennStateRi3D]

We have it hit a hard endstop at 0 degrees and in the scoring position, but I don’t know the angle, but you could get the exact measurement from the CAD.
