Our team competed at a week 1 event with a 4-bar harvester made primarily of polycarb. While it was successful, we had a few snapped bars throughout the season and are re-fabricating the parts out of sheet metal. In order to save weight on our robot, we plan on trussing the plates and metal side plates of the shooter.
Unfortunately, our team has no experience with this. I am wondering if anyone has any advice or insight of how to design them in a smart and efficient way in CAD?
Edit: I have confirmed the arms were made of acrylic and not poly and that change will be made. However, we still are going to truss other plates on our robot including a modified version of the Greyt Shooter.
