<R36> specifically allows unmodified COTS parts from previous robots; if you consider the controls part of the robot, that allows the old, out-of-production CH Flightsticks. Unmodified COTS parts from ebay... I don't know. Definitely a Q&A worthy question. Wheels aren't really that complex anyway; we will probably be building one for testing purposes, if not for the final implementation. I suggest telling a couple of newbies to build one; even if you don't use it, it'll be a great learning experience.
