At present, intelligent ship has become a new hot spot of international maritime research and development. In order to achieve the purpose of safety, reliability, energy conservation, environmental protection, economy and efficiency, Intelligent ship integrates modern information technology, artificial intelligence technology and other new technologies with traditional ship technology. In this essay, the rapid development of intelligent cabin technology in recent years is surveyed. The intelligent cabin technology and the development trend of the current technology is analyzed, and the possible development direction in the future is pointed out. Collection, transmission and storage of sensor data are summarized. The development of status perception of cabin equipment and environment is discussed. Data-driven intelligent applications are summarized, and the development in the future is discussed. Intelligent cabin system is a data driven information system, which involves data acquisition, communication, storage, analysis, visualization and other rich content. Using the data provided by intelligent ship, more and more intelligent applications will be developed for ships.

The double quaternion represents the double rotation in four-dimensional space. It has the advantage of fast computing, robustness, and no singularity, hence the double quaternion can be used in the trajectory planning of the robotic manipulator. To make the position and orientation of the end-effector change continuously and smoothly in the trajectory, another compliant trajectory planning algorithm is needed. Algorithms based on Tau theory are an ideal solution since they use the inner mechanism of humans and animals plan trajectories and the planned trajectories are compliant. The effectiveness of the proposed method is verified on both virtual and real robotic manipulator.
