Like I did last year, I’ll be doing another robot CAD speedrun with a kickoff watch-along at 8:30 PST. Feel free to stop by and chat!
I’ll also be using the FRCDesignlib library w/ a modified workflow based on the frcdesign.org curriculum.
To make it better than last year, I’ll try to reduce the scope and not attempt to try to do whatever is the trap this year.
Like usual, I’ll be streaming it on my YouTube channel, which you can check out here: https://www.youtube.com/live/Ll93tfcq140?feature=shared
A live doc w/ notes and updates will be filled out here (with CD updates):
Constraints:
MFG: 2D Laser cutting service/Omio, 3D Printer, Drills, Drill Taps, Bandsaw
1/4 + 1/8 Aluminum
1/4 Polycarbonate
Punched Box Tubing w/0.5-inch increments and a 0.5-inch hole offset.
1/2 Rounded hex
If I can get it cots and it is more reasonable to be COTS I’ll use COTS
Drivebase:
WCP X2I with citrus-style bumper mounting
Design Constraints:
If it is a shooter, choose one fixed ranged position to shoot from
If it is pick and place, attempt to to do it with a linear actuation with a short rotary mechanism
If it’s a hybrid, cry.
Since the game involves multiple game pieces, I’m curious about how my constraints might change or how my decision-making may change because of that.
It needs to be able to be finished in under 16 hours (but I have spare time for extra CAD days)
The goal is to try to do at least the basic scoring functions in the simplest way possible while following good design principles. (low cg, no large mechanisms outside of FP, no large cantilevers, etc)
Detail:
Try to get all the important fasteners, don’t need full detail but I’ll try to get to a point that you would use for competition CAD.
CAD Practices: Try to use Multi-doc with “best” practices regarding workflow, folders, and naming are not required.
I am unsure if I will be using krayoncad or block cad for this particular workflow, we’ll see.
Theoretical Stream Schedule: (In PST/California time)
8:30 AM: Start Stream
8:45 AM: Kickoff Starts
9:15 AM ish: Run through game manual to grab important values, start determining game flow
10:00 AM: Start playing with architectures in sketch, try to have at least 5 different ideas before settling/going down. If have extra time, make drivetrain.
12:30 PM: XRC game release, cycle to get a better feel of game based on theoretical strategy.
3 PM Settle on architecture and start part studios
8 PM: Start assemblies
11 PM: Detailing and finish?
I probably am underestimating how much time I will take, and I will probably do it over the weekend. Regardless, I’ll try my best.
Breaks will be added between, depending on when I feel like it.
Thank you!
