Abstract
A steering compensator has a shaft with a first shaft section offset from a central shaft section. A second shaft section of the shaft is offset from the first and central shaft sections. A first drive member is rotatably attached to the first shaft section and a second drive member is rotatably attached to the second shaft section. A central member is rotatably attached to the central shaft section between the first and second drive members. A pivotal link interconnects the first and second drive members through the central member to allow relative angular displacement between the first and second drive members. The steering compensator provides steering angle correction in conventional steering. A crab-conventional camera dolly steering shift mechanism has shift plates and sprockets aligned on a shaft. An electronic shifter automatically shifts between crab and conventional steering modes.
