Hi, going from small to big usually means giving high power..
ie, instead of using small motors for your small doors, you will have to use some higher capacity motors, and you have to provide the high current to drive them too.
The logic and all will remain the same. only thing is, at the output stage, you use various stages of power amplifiers to give the required power to your output signal to help drive larger motors.

That will be all I think. Hope I'm clear..
