“…The authors described a technique to overcome undesired scatter in images using polarized light, which is similar to the work presented by Schechner et al [28]. Additionally, Yoshida [29] presented a review of the available embedded system used in underwater robots, which includes their hardware specifications.…”

“…Wireless communication research is also already conducted using underwater accoustic communication and underwater optical communication [8][9][10]. Some of the researh in wireless communication is conducted in simulation method with multimodal wireless remote control [11][12]. There are three types of purposes using this wireless communication such as video, data transfer and Position and Navigation-GPS.…”

Disaster recovery from underwater earthquake, plane crashes into the sea, and monitoring underwater cables or piping for energy purpose are underwater missions for Remotely Operated Underwater Vehicle (ROV) in ASEAN MATE 2018 Competition. Two essentials factor to perform successfully in this ROV competition are design of an efficient communication protocol system and a low-cost communication hardware. In this research, an optimal communication system between RS-232 serial communication transmission and RS-485 serial communication transmission is developed to obtain the optimal solution. Both communication system is tested in Tech_SAS ROV-Telkom University Indonesia, a microcontroller underwater ROV based which used single microcontroller to control actuator, sensor and communication, and measured the Quality of Services (QoS) for end-to-end delay and packets loss. From the the experiment and evaluation for the two schemes, shows 12.57 ms end-to-end delay, 0% data packet error and $6 RS-485 communication system are the optimal solution for Tech_SAS ROV.

“…Core samplers such as gravity samplers [5] and piston samplers [6], are used to collect sediment samples. Using soil samplers, a Remotely Operated Vehicle (ROV) or an Autonomous Underwater Vehicle (AUV) conducts core sampling [7] [8] in some situations. In the case of an ROV, while watching video images sent from cameras mounted on the ROV, operators or scientists are able to ascertain whether a place is desirable or not, and can check whether core samplings are done suitably or not.…”

This paper presents development and motion evaluation of a human-portable underwater robot for soil core sampling. The developed robot is a remotely operated vehicle (ROV) with a core sampling pipe. In general, core sampling devices are heavy and penetrate into the soil by their own weight. In contrast, the developed robot is lightweight and penetrates the soil by its thrust force. This robot has neutral buoyancy; it can therefore move to desired areas using its thrusters. As explained in this paper, we describe the robot specifications and present results of preliminary experiments for the motion performance. Experiments in a test tank demonstrate its static stability, vertical motion for core samplings, and other beneficial features. Moreover, field tests in a lake demonstrate the feasibility of the developed core sampling robot. The soil penetration depth was approximately 0.16 [m] in the first trial.
