A gimbal mechanism includes a first actuator configured to provide rotation about a central actuator axis at a first actuator speed, a second actuator co-axial with the first actuator and configured to provide rotation about the central actuator axis at a second actuator speed, and a differential member including a differential gear operatively coupled to the first actuator and the second actuator and a shaft extending between the first actuator and the second actuator. The shaft has an input end coupled to the differential gear and an output end coupled to the payload. The differential member is configured to rotate freely about a differential member axis extending along a length of the shaft. The first actuator and the second actuator are configured to cause the payload to rotate about the central actuator axis, the differential member axis, or both, based on the first actuator speed and the second actuator speed.
