| Summary: | 碩士 === 國立成功大學 === 系統及船舶機電工程學系 === 106 === Based on the customized small-ROV, the purpose of this research is to integrate the propulsion system, attitude sensing system, depth sensing system and photographic lens into the internal system and and improve the technology. Combing human factors engineering design methods to optimize user interface, so that the system interface will meet the operational requirements of underwater archaeologists and improve work efficiency. And we take place the experiment to test the the operation, stability and photography after program optimization in NCKU towing tank. Additionally, we will conduct the field test in saline waters and try to build a 3D model of the water area in the field with the underwater photogrammetry.
It is not easy to control the pitch and roll attitude of the ROV. In order to overcome this problem, the automatic depth and path prediction function of the system will be added with the depth and attitude sensor. Improvements on the ROV, including program optimization, cabin and propulsion system layout, center of gravity and center of buoyancy adjustment and sensing system. The human-machine interface is integrated with the human factor engineering design method, and the gamepad and joystick are added for different users to choose suitable control methods.
According to the results in this research, the gamepad can help reduce the learning time. And if the user uses the controller more frequently, it will also reduce the learning time. Consequently, the modified interface allows the small ROV to meet the operational requirements of underwater archaeology. We have also conducted two nearshore tests and one offshore test, in which we found problems and tried to solve them. Nevertheless, the choking and positioning control still need to be improved in the future.
