ABSTRACT:
The present invention provides various clutch/gear assemblies that can be driven by a single motor. The clutch/gear assemblies comprise a smart material which changes shape when supplied with energy, e.g., current or heat. The smart material achieves one of a first or a second shape when supplied with energy, and achieves the other shape when it is not supplied with energy. When the smart material achieves a first shape it causes a clutch surface of the clutch/gear to engage and be driven by a shaft coupled to the motor and when the smart material achieves a second shape it allows the clutch surface to disengage from the shaft.
