A stepper motor/DC motor to move the machines pot... effictively similar to the 'fly by wire' throttles in modern cars?
Only improvement that could made to a traditional style pedal is to make 'em cordless imo (one less cable to trip over)
You could take a step back from the "fly by wire" and drive by cable. Push bike gear cable, some pulleys and a return spring. Simple, effective, direct.
Or if you want to go cordless, what about model RC gear, not sure about the torque requirements but it would be a nice little project.
