Took me 10 minutes. I think I love it.
Some immediate thoughts:
The telescoping arm has too many knobs, especially things like “wall thickness” that don’t seem relevant. Could remove those and maybe simplify some stuff.
The four bar intake has a lack-luster set of adjustment knobs, but it’s implementation is slick.
Overall, I’m impressed with the strategic use of provided mate connectors to make pulling these assemblies together very quick.
Nice work!

Anything that helps new kids get into using CAD, I’m onboard. Can’t wait to try this out and get kids doing mock ups.
The turret shelf goes crazy.
Awesome idea and many thanks for sharing this with the broader community! Look forward to playing around with it and incorporating into our robot conceptualization efforts.
Was able to put together two concepts in ~15 ish minutes. We’ll definitely be looking at how we can implement this program in the season. Thanks for sharing!
For my team, I’m thinking that during kickoff when we have the students split off into groups to explore robot architectures, typically they create those with whiteboard sketches. So ideally I can just assign a CAD student to each group with a laptop and they can create a KrayonCAD robot as well.
I’llLimelight, an integrated vision coprocessor be trying this out for our mock kickoff on early December and report back.
This is cool. I was thinking about making something similar to this last season, but this implementation is above and beyond. I think we’re going to use this heavily in the upcoming season.
My only major note after a few minutes of tinkering is that it would be nice to have some more options for frame members. “Rectangular frame” and “triangular frame” with options for “planar” or “prismatic” would be a huge time saver over having to manually mate 2x1s in place.
Edit:
This is exactly the use case I was thinking of when I was exploring the idea.
Can you elaborate on this part? I like this suggestion a lot!
Planar rectangular frame:
Prismatic rectangular frame:
Planar triangular frame:
Primsatic triangular frame:
The triangular frame might have too many variables to be viable here, but the benefit of the planar vs. prismatic is that you could stick a mate connecter in the middle of a prismatic structure and mount your mechanisms symmetrically without having to do any extra tedious work.
(((#Ball_Diameter/2+2.5in+0.75in+#Roller_Diameter/2+0.25in)-(-(((#Ball_Diameter/2 + #Roller_Diameter/2)^2 - (#Ball_Diameter/2 + #Roller_Diameter/2 - 0.75in)^2)^0.5)))^2 + (#Bumper_Top_Height+0.5in+#Roller_Diameter/2-((#Ball_Diameter/2 + #Roller_Diameter/2 - 0.75in)+#Ball_Diameter/2))^2)^0.5
This was the “code” to make the 4bar generate. And this was just to generate the motion/actual intake part of it. We wanted to make it have the bars as well but it simply would’ve been too complicated, so we instead made it our goal to mimic the motion of a 4 bar, as it does now.
Maybe at some point someone would figure out how to generate the whole thing…
Any specific things that could make the 4bar better?
I used the beta version put on discord a little bit during our mock kickoff a couple weeks ago. Overall a great experience and we found it helpful to have a person using the program.
I found it super helpful to visualize how the robot was gonna look, especially since it was a mock kickoff and we weren’t getting super deep into design.
Just to clarify that “code” was to define the limit of motion of the 4bar, not generate the geometry. It was just clever sketch that had a good balance of resiliency and correct-ish roller positions. The mates were setup to mimic the motion of the 4bar not necessarily provide “correct” motion
Supper sick! I am definitely going to use this next year!
It took me like 15min to mock up our robot from this past year:
4 bars are inherently complex and bringing them down to a few variables is a little tricky. I think these are the numbers I’d want to be able to play with. The mid and back roller positions effect the stowed height which is why they’re worth being adjustable, although you’re going to have to work out how to communicate those terms clearly.
Oh my… You and your team have made my day!
Thank you so much. I’m going to take this out for a spin.

Can confirm this is very cool. Wild to watch how quickly and well organized the development went. Looking forward to its use in the season!
Wow, amazing initiative!
I already shared the group, sure we will use it
Really appreciated 
Gotdam Nick. I got to share this with my team a couple of weeks ago and can confirm that it is fabulous new resource. Thanks so much for all your work on this.
