摘要： A control system includes a locomotion device that is configured to accompany a moving object such as a human operator or a robotic device. The control system is configured to control a motion of the locomotion device based on a location of at least one of the moving object relative to the locomotion device or a location of the locomotion device relative to the moving object. The control system is configured to control the locomotion device to maintain a position of the locomotion device with respect to the moving object to thereby synchronize the motion of the locomotion device with a motion of the moving object.

摘要： An azimuth thruster system includes a pod configured to rotate relative the hull of the ship about an azimuthal axis of the pod, a propeller shaft extending from the pod and being configured to rotate relative to the pod about a central axis of the propeller shaft, an outer shaft disposed at least partially in the pod and configured to be driven by a first primary prime mover, an inner shaft disposed at least partially within the outer shaft and configured to be driven by a second primary prime mover, and a pod gear unit disposed within the pod and coupled to the outer shaft, the inner shaft, and the propeller shaft. The outer and inner shafts are configured to rotate at least one of the pod and the propeller shaft based on directions and magnitudes of the torques generated by the first and second primary prime movers.
