We used CIM motors for the top arms, after trying the FP motors with the AndyMark planetary box... Not enough power.
We didn't collaborate on the design. Kirk Oden, Justin Beardsley, and I designed the 3rd stage elevator and hook actuator. The students helped determine the best shape for the hook, keeping simplicity in mind. Since it is comprised of two simple components, a hook and a stabilizer, I imagine lots of teams will have similar looking devices.
