Special Issue Information

Dear Colleagues,

With the rapid development of the global economy and technology, there is an increasing demand for tasks such as underwater operations and exploration. Underwater robots, as an advanced underwater work tool, are undertaking increasingly underwater work tasks and have received rapid development and high attention from countries around the world.

To better complete tasks, underwater robots must consider different types of uncertainties and achieve efficient and robust interaction between the environment and the robot. Underwater robots should be able to make autonomous decisions to reduce the burden on operators. For example, robots can automatically adjust their motion control mode, select suitable sensors for data collection, or perform basic task planning based on environmental conditions and task requirements. In addition, virtual reality technology, posture recognition and other technologies can provide operators with more intuitive and immersive underwater robot operating experience. With the development of artificial intelligence technology and machine learning technology, underwater robots will continue to become intelligent, possessing higher levels of autonomous decision-making, autonomous control, and task planning capabilities. At the same time, they will also have multi-agent collaboration functions, which can achieve cooperation, joint cruising, and task execution among multiple robots.

This research topic is dedicated to collecting the latest development and research findings, addressing theoretical and practical issues related to advanced methods, path planning, adaptive control, and signal processing in underwater robot systems. The aim is to provide a platform for researchers and practitioners to showcase and discuss innovative solutions.

Topics of interest include, but are not limited to:

  • Underwater robot control system based on deep learning or reinforcement learning.
  • Teleoperation control of ROV/AUV/AGV
  • Multimodal data fusion for underwater robot control
  • Path planning for ROV/AUV/AGV
  • Collaborative or semi-autonomous control of multiple robots
  • Posture recognition and localization
  • Intelligent wearable and assistive robot devices

Detecting objects, particularly naval mines, on the seafloor is a complex task. In naval mine countermeasures (MCM) operations, sidescan or synthetic aperture sonars have been used to search large areas. However, a single sensor cannot meet the requirements of high-precision autonomous navigation. Based on the ORB-SLAM3-VI framework, we propose ORB-SLAM3-VIP, which integrates a depth sensor, an IMU sensor and an optical sensor. This method integrates the measurements of depth sensors and an IMU sensor into the visual SLAM algorithm through tight coupling, and establishes a multi-sensor fusion SLAM model. Depth constraints are introduced into the process of initialization, scale fine-tuning, tracking and mapping to constrain the position of the sensor in the z-axis and improve the accuracy of pose estimation and map scale estimate. The test on seven sets of underwater multi-sensor sequence data in the AQUALOC dataset shows that, compared with ORB-SLAM3-VI, the ORB-SLAM3-VIP system proposed in this paper reduces the scale error in all sequences by up to 41.2%, and reduces the trajectory error by up to 41.2%. The square root has also been reduced by up to 41.6%. Full article

In order to solve the problem of how to perform path planning for AUVs with multiple obstacles in a 3D underwater environment, this paper proposes a six-direction search scheme based on neural networks. In known environments with stationary obstacles, the obstacle energy is constructed based on a neural network and the path energy is introduced to avoid a too-long path being generated. Based on the weighted total energy of obstacle energy and path energy, a six-direction search scheme is designed here for path planning. To improve the efficiency of the six-direction search algorithm, two optimization methods are employed to reduce the number of iterations and total path search time. The first method involves adjusting the search step length dynamically, which helps to decrease the number of iterations needed for path planning. The second method involves reducing the number of path nodes, which can not only decrease the search time but also avoid premature convergence. By implementing these optimization methods, the performance of the six-direction search algorithm is enhanced in favor of path planning with multiple underwater obstacles reasonably. The simulation results validate the effectiveness and efficiency of the six-direction search scheme. Full article
