FTC CAD Competitions
I have competed in three “FIRST Tech Challenge” themed CAD Competitions since 2020 as a way to continue expanding my skill-set and speed in Solidworks and Autodesk Inventor. Each competition had a time limit of 7 days and I succeeded in winning the 1st place Innovation Award with my 2020 and 2023 submissions.2025 - LOGICoyote CAD Challenge
This was my most ambitions cad competition robot yet, with a goal of using only four brushed motors and one hobby servo (the limits are 8 and 12 respectively) to design a robot that would complete all game tasks. Though I ran out of time to complete the full robot due to work, I did complete a unique and complex “spin-shifter” style transmission and a 5DOF arm concept that I intend to utilize in future competitions. I am proud of the transmission for this project, and would like to manufacture an updated version in the future. A more complete write-up of this project is in the works as of May 2026.Link to shared transmission CAD in Onshape
Here is a view of the transmission and motors (I call it the "Power Pack") with one of the main covers removed. A partially labeled bottom view is presented as well.
To complete game tasks, the power pack was used to run a 5DOF arm with a mechanical tool changer, and the outputs of the differential would be connected to a skid-steer drivetrain through a set of coaxial pulleys. This gives the turret an unlimited amount of travel and the electronics can be mounted without an electrical slip ring.
