Development of an Internet-based Operating Interface for ROV Pilots

Due to the expense and logistics involved with operating real remotely operated vehicles (ROV), training and practice is often difficult to obtain. Therefore, many researches were conducted to increase ROV pilots' experiences through virtual reality. However, most of the training systems that are in use today can only be controlled by a single operator. When two or more ROVs work in a same area, it needs proper concordance among pilots in order to avoid accidents such as collision or cable entanglement. Therefore, this study aims at the development of a ROV operating interface featuring simulated training, remote monitoring, and multiple-user connections. For fulfilling the requirements of remote monitoring, simulated training and multiple-user connections, this study employs JAVA and GL4Java in developing the ROV operating interface. This way we benefit from the 3D description capabilities of GL4Java while JAVA is utilized for the processing and manipulation of web interactions. The developed system architecture includes a server and a client. The client can connect to server by using the web browser through the internet or a LAN with TCP/IP. The server contains required data of sea floor topography and ROV dynamics related parameters. As well, the server is responsible for communicating with the clients. On the client site, it is responsible for sending commands, receiving sensor data and keeping the local information up to date. In remote monitoring, the server periodically integrates and records ROV positioning data and then transmits them to the client. The client receives the updates of ROV status information and displays them on the graphical interface. In simulated training, the equations of motion of ROV are computed on the client-side and only simulated positioning data is reported to the server. In addition, the system allows users to modify underwater visibility, intensity of ambient light and terrain texture for simulating diverse operation conditions.
