1. An electro-polymer motor, the motor comprising:

  • a fixed member;

    a first actuator having a first end fixedly connected to the fixed member and a second end, the first actuator comprising a polymer positioned between two electrodes, wherein the electrodes are in communication with a power supply;

    a driven member comprising a body having an axis, wherein the driven member is fixedly connected to the second end of the first actuator; and

    a compressible member having a first end fixedly connected to the fixed member and a second end fixedly connected to the body of the driven member, the compressible member spaced apart from the first actuator;

    wherein the first actuator changes length after the power supply applies a voltage across the electrodes to move the driven member.
