Dating back to 2013 (Ultimate Ascent), here are the links to the Onshape documents containing 293 SPIKE’s robots. We started using Onshape for the 2016 season, transitioning from Solidworks. The 2013-2015 documents are imported from solidworks, so while all parts are there, mates are missing.

I’ve been on the team since 2020, so if you have any questions about designs from then onwards, I’ll probably be able to answer them for you. If you have questions about past designs, I can reach out to the alumni who worked on them to get an answer. I have to get sharing permissions for the 2022 document before i can publish it, but I’ll edit this topic to include it once I’m able to make it public.
