A motive device for use in magnetically sensitive environments includes a front supporting plate, a rear supporting plate, and at least one guiding rail extending longitudinally between the front and rear supporting plates and supported thereby. At least one module is supported by the guiding rail, is located longitudinally between the front and rear supporting plates, and is configured to provide at least one of translational and rotational motions to a moved structure extending from the at least one module longitudinally toward and beyond the front supporting plate. The translational motion is guided by motion of the module between the front and rear supporting plates longitudinally along the at least one guiding rail. The module provides the at least one of translational and rotational motions to the moved structure entirely pneumatically. The structures comprising the motive device are all made entirely from non-ferromagnetic materials.
