ABSTRACT:
A linear voice coil actuator using a removable electromagnetic coil includes an electrically conductive wire wound on a plastic bobbin. The wire which is wrapped around the bobbin is connected to an external power source as the electromagnetic coil is attached to the linear voice coil actuator. Current applied from the external power source causes the electromagnetic coil to selectively generate a magnetic field and, in response to generation of the magnetic field, to move translationally within a fixed magnetic field. The translational movement of the coil moves a grip which is mounted on the coil to allow the grip to selectively position and manipulate objects and things.
