07 - Analysis of a New Twin Hybrid Autonomous Underwater Vehicle.
Authors: Jiafeng Huang, Hyeung-Sik Choi, Dong-Wook Jung, Ki Beom Choo, Hyunjoon Cho, Phan Huy Nam Anh, Ruochen Zhang, Joon Young Kim, Daehyeong Ji, Jung-Hyeun Park The “twin hybrid autonomous underwater vehicle” is a novel unmanned underwater platform consisting of a twin torpedo-shaped hull actuated by two buoyancy engines and two thrusters. It was designed to have faster speed generated by the two buoyancy engines and two thrusters. The two buoyancy engines on each hull and the airfoil are mainly responsible for the diving and surfacing motion, and the thrusters drive it along the horizontal plane. It can carry more instrumentation and energy than a conventional hybrid autonomous underwater vehicle and perform more exploration tasks for extended periods.
08 - Design and Construction of Hybrid Autonomous Underwater Glider for Underwater Research.
Authors: Simon Siregar, Bambang Riyanto Trilaksono, Egi Muhammad Idris Hidayat, Muljowidodo Kartidjo, Natsir Habibullah, Muhammad Fikri Zulkarnain, and Handi Nugroho Setiawan The main goal of this paper was to design and construct a hybrid autonomous underwater glider (HAUG) with a torpedo shape, a size 230 cm in length and 24 cm in diameter. The control, navigation, and guidance system were executed simultaneously using a Udoo X86 minicomputer as the main server and three BeagleBone Black single-board computers as the clients. The simulations showed a controlled horizontal speed of 0.5 m/s in AUV mode and 0.39 to 0.51 m/s in glide mode with a pitch angle between 14.13 deg. and 26.89 deg.
21 - Lightweight underwater robot developed for archaeological surveys and excavations.
Authors: Shohei Hotta, Yusuke Mitsui, Mizuki Suka, Norimitsu Sakagami, and Sadao Kawamura. This paper reports the development of a lightweight remotely operated vehicle that performs underwater excavation work for archaeological surveys. Discovering underwater artifacts is generally difficult because they are often covered with sediment in high- risk areas. To find them, divers and large remotely operated vehicles must conduct excavation work with manipulators. Nevertheless, accomplishing such tasks is difficult for small underwater robots without a manipulator. For this reason, the authors developed a lightweight underwater robot of 35 kg that can remove sediment from the seabed or lake bottom using its thrusters instead of a manipulator.
23 - Review of Localization and Clustering in USV and AUV for Underwater Wireless Sensor Networks.
Authors: Kaveripakam Sathish, Ravikumar Chinthaginjala Venkata, Rajesh Anbazhagan, & Giovanni Pau Oceanographic data collection, disaster prevention, aided navigation, critical observation sub-missions, contaminant screening, and seaward scanning are just a few of the underwater sensor hub submissions. Unmanned submerged vehicles (USVs) or autonomous acoustic underwater vehicles (AUVs) through sensors would similarly be able to explore unique underwater resources and gather data when utilized with integrated screen operations. The most advanced technological method of oceanic observation is wireless information routing beneath the ocean or generally underwater.

Authors: Qiyun Cheng, Wenyuan Mo, Long Chen, Wei Ke, Jun Hu, and Yuwei Wu. Underwater robotics is rapidly evolving due to the increasing demand for marine resource exploitation. Compared with rigid robots using propellers, bionic robots are stealthier and more maneuverable, such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs), making them widely used underwater. To study the motion state of the umbrella jellyfish bionic robot, the displacement of the jellyfish robot along the same direction and the surrounding fluid pressure distribution caused by the jellyfish motion under different experimental conditions are discussed in this paper.

Authors: Zhiyong Duan, Yurui Zhang, Jiaqi Hu, Bohao He, and Canjun Yang At present, contact watertight connectors are commonly utilized for the connection between underwater electromechanical equipment and the seabed observation network. Such traditional watertight connectors are easy to be irreversibly worn when plugging and unplugging, however, they have complicated sealing structures and limited service life. This paper designs a Non-contact Wet Mateable connector for Optical Communication and Power Transmission (OCPT-NWMC), which is based on technology of Contactless Power Transmission (CLPT) and optical communication.

Authors: Fauzal Naim Zohedi, Mohd Shahrieel Mohd Aras, Hyreil Anuar Kasdirin, Mohd Bazli Bahar, & Lokman Abdullah The underwater environment makes it hard for ROV operators to control the manipulator while holding position simultaneously. This led to modelling and controller design for the vertical trajectory of ROV. In this paper, the System Identification (SI) modeling technique was used to model the vertical trajectory of the ROV. Then, the Proportional, Integral, and Derivative (PID) controller was implemented to control the trajectory.

However, this system suffers from severe dynamic coupling effects due to the combination of a small vehicle and large manipulators. The authors propose a robust adaptive controller to resolve this issue.

31 - Dynamics of an Autonomous Underwater Vehicle (AUV) towing another AUV
Authors: Stefano Brizzolara, Alan Brown, Craig Woolsey, Daniel J. Stilwell This thesis proposes a method to simulate the dynamics of an autonomous underwater vehicle towing another autonomous underwater vehicle of equivalent size using a marine cable in the vertical and horizontal planes. There is a coupling effect between the two vehicles because the towed vehicle is of equivalent size. This means that the towed vehicle cannot be modeled as just a payload but rather must incorporate the forces and moments experienced and acting upon it. In this work, only AUVs with symmetrical hulls are considered, where the towing AUV moves at a constant velocity with a set thrust, while the towed AUV has no thrust.
32 - Underwater ice adaptive mapping and reconstruction using autonomous underwater vehicles
Authors: Shuangshuang Fan, Xinyu Zhang, Guangxian Zeng, and Xiao Cheng) The undersides of floating ice shelves and sea ice in the Antarctic and Arctic are among the least accessible environments on Earth. The interactions between ice shelves, sea ice, and the ocean are of considerable scientific interest. In order to fully understand the complex picture of sea ice, and not just its surface, it is necessary to map the underside to comprehend the full context of its growth and decay patterns. Autonomous Underwater Vehicles (AUVs) are rapidly becoming the desired platform of choice for mapping the underside of sea ice to provide high-resolution 3D views of sea ice topography.

Therefore, it is necessary to study the influence of data loss on the static magnetic source location of underwater vehicles and the field source location for timely remediation of missing data. In this paper, the static magnetic equivalent source model of the underwater vehicle was established. Then, the inversion positioning algorithm was used to locate the magnetic field source of the underwater vehicle obtained from the test, and the influence of the location result under incomplete data information was analyzed.

Authors: Yuzhe Wang, Pengpeng Zhang, Hui Huang, and Jian Zhu Jellyfish are among the most widely distributed creatures that can effectively control the fluid flow around their transparent soft bodies, thus achieving movement in water and camouflage in their surrounding environments. Until now, it has remained a challenge to replicate both the transparent appearance and functionalities of nature jellyfish in synthetic systems due to the lack of transparent actuators. In this work, a fully transparent soft jellyfish robot has been developed to possess both transparency and bio-inspired omni-motionin water.
44 - Dynamic analysis of launching and recovering ROV
Authors: Yulin Deng, Xiudi Ren, Martin Nuernberg, Longbin Tao ROV often experiences excessive motion as it passes through the wave zone due to wave-ROV interaction combined with free surface effects. These movements can cause rope slack and sudden loading, which may damage umbilical components and endanger ROV operation. This study focuses on experimental measurements and numerical predictions of the dynamic tension in the umbilical during the launch and recovery of the ROV.
