The increasing demand for underwater robotic intervention systems around the world in several application domains requires more versatile and inexpensive systems. By using a wireless communication system, supervised semi-autonomous robots have freedom of movement and, at the same time, allows the operator to get camera feedback and supervise the intervention. Moreover, the limited and varying bandwidth of underwater radio frequency (RF) and underwater acoustic modem channels is a major obstacle. This paper proposes the use of progressive (embedded) image compression and region of interest (ROI) for the design of an underwater image sensor to be installed in an Autonomous Underwater Vehicle, specially when there are constraints on the available bandwidth, allowing a more agile data exchange between the vehicle and a human operator supervising the underwater intervention.

This paper presents the current state of the development of a Wireless HROV (Hybrid Remotely Operated Vehicle HROV), providing feedback of both, camera and telemetry data to the operator, over an acoustic communication link. This experiment is part of the MERBOTS Spanish national project (www.irs.uji.es/merbots). This work has as main objective the design of a bidirectional transport protocol for wireless teleoperation of an underwater robot using high level commands and a progressive image compression algorithm. Preliminary Hardware In the Loop results combining two S2CR 18/34 modems in a scenario with high level of multi-path, a freshwater pool, and the UWSim simulator are presented. Finally, a ROS-based network simulator that is still in an early stage of development is presented. This simulator will be useful for modeling high-level behavior of any communication device, and to improve high level protocols when the real modems are not available.

Autonomous manipulation in real underwater environments presents many unexpected situations, such as lack of visibility due to light reflections or presence of particles in the water. Moreover, the use of cameras is still very important, considering that they provide a natural sensor input to the operator, and many robust and efficient underwater manipulation algorithms have been implemented using this kind of sensor. Moreover, underwater applications, especially the ones that may involve interacting with artificial structures like panels, or even with other robots, would be very much improved if the umbilical cable could be substituted by a wireless system, improving so mobility. In that sense, Radio Frequency connection, allowing the transmission of camera input to the operator, would be a potential improvement. The present article describes the system implemented at the TRITON project (www.irs.uji.es/triton) in order to localize a robot arm related to a panel with a valve and a connector, using sonar and radiofrequency techniques, in order to experiment autonomous manipulation under lack of visibility conditions. Moreover, the Radio Frequency system enables the transmission of camera monitoring information at small distances, which has previously been compressed using specific techniques.
