You might be able to do control systems from the mechanical engineering side, which will teach you about mechanisms for sure. I know at SDSM&T, where I went, all the MEs had to take an introductory controls class--I want to say it was a sophomore-level course, and taught by one of the ME profs. (We also had a circuits class and a mechatronics class that were both required, and both junior-level courses, plus senior design projects.)

Not all control systems are electronic; sometimes a mechanical one will work quite well also. I believe that a Geneva mechanism was discussed on CD as a viable climber option this year, for example.
