If you aren’t familiar with what a CADathon is, it’s basically a competition in which several teams or individuals compete to design something in CAD in a short period of time. In the case of the biannual F4 CADathon it was to design a full FRC https://www.firstinspires.org/robotics/frc robot in just a week (Usually 3 days but I guess they extended it because of covid). This time I chose to work on a random team of three people. One guy was from Texas and the other guy was from somewhere near the east coast I think. The goal for the robot this time around was for it to pick up and shoot footballs as well as pick up and place weights. I worked on the full football system leaving the rest of the robot for the other two guys. I also did the finishing touches (rendering and making sure everything looked nice) We all used SOLIDWORKS for everything.
The team had decided to make everything with sheet metal. This was my first time using sheet metal in SOLIDWORKS. After having made a prototype of the football system, I moved onto the final design. It was very important that everyone’s work fit together properly on the robot so we used GrabCAD to organize our files and it worked out great. Since this robot design didn’t need to be manufactured (still must be somewhat feasible), I got kinda carried away when designing certain things such as the transmission systems and the sheet metal parts. In the indexing system 11 axis are driven by one motor. The drive system and the lift were both pre-built before the CADathon. Pre-built parts are allowed so long as they are publicly available. I created all the parts I used (excluding COTS items). Below is a gallery of more pictures of the CAD. Thank You!
