Hello,
We are the Robodox from Granada Hills Charter High School and this is the CAD for our robot so far! We would like to give a huge thank you to Industrial Metals Supply Co for giving us the stock material required to make our parts and access to their CNC machines for the more intricate ones.
See you guys soon at competitions!
Link is private, I can’t access it. 
EDIT:
Beautiful integration of your systems! How does your intake work to load the ball into your catapult?
Fixed! thanks for letting me know 
Think I figured it out - over the bumper intake?
Are you using Solidworks? We are stuck with it, and TBH, I find it a bit annoying because of lack of support. A lot of files that are a pain in the *** to convert.
Are those “speed lines” or cut off urethane belt?
Yes we are using Solidworks 2015. We have been using this software for a few years already. What do you mean by lack of support?
Which part of the robot are you speaking of ? 
Look like torsion springs for the catapult.
Oh yes, those are custom torsion springs for a 1" rod.
Actually no. Because the rules only require 8" of bumber around each corner, and our robot is around 27" wide (Approx), there is a gap in the middle where the intake is placed. However, we do use the chassis rail to help grab the ball. Does that make sense?
Thanks for the compliment means a lot! It may be kind of hard to see but on the front chassis rail is a small piece of vertical lexan. This piece of lexan bends and helps the ball climb up. It reaches a point where the ball goes over the lexan and the lexan bends back into position. Through prototyping, we found that the ball falls into the place where we put the catapult head. We are probably going to add more lexan “Walls” near the catapult head to help the ball fall into place. Does that answer your question? Feel free to ask more questions if you want!

For support have you tried the SolidWorks section of Chief Delphi? Another place great place to get help is at

See the second sentence. If I download a .STEP from VexPro, like a mechanum wheel, nothing is mated. It is all a bunch of imported parts. So, I have to mate everything or some other temporary fix. Overall, it is a lot harder of a workflow than my other Autodesk programs that I have at home, IMHO…
(Plus, Autodesk is an official sponsor of FRC, so it is rather awkward when we are asked by an Autodesk volunteer how we drafted the robot, and we mention that we did it through solidworks. XD )
Typically I found it simplest to highlight the hole imported component and right click and fix it in place, maybe not the best method but it works alright.
I could be off here, but isn’t Solid Works a sponsor as well?
I know for sure they have in the past. Regardless, #InventorMasterRace
