Recently, as humans have become increasingly interested in ocean resources, underwater vehicle-manipulator systems (UVMSs) played an important role exploitation. To realize precise operation narrow spaces, the fly arm vehicle manipulator system (FAUVMS) is proposed with manipulators its core. However, this suffers severe dynamic coupling effects due to combination of small and big manipulators. resolve issue, we propose a robust adaptive controller that contains two parts. In first part,...
Currently, for underwater close-range large-target localization, visual localization techniques fail since large targets completely occupy the camera’s field of view at ultraclose ranges. To address issue, a multi-stage optical method combining binocular camera and single-point laser rangefinder is proposed in this paper. The comprises three parts. First, imaging model modified, used to further correct calibration results camera. Second, YOLOv8 applied recognize prepare target localization....
Abstract The immune response induced by surface topography crucially determines the implant success. However, how is mediated size of remains unclear. Hence, various biocompatible Mg-Al layered double hydroxides sheet-array films with different sizes (nano, micro and nano/micro mixture) were constructed on biomedical titanium, their osteo-immunomodulation effects macrophages explored. nano-sheet array structures significantly promoted polarization M2 activating PI3K-AKT-mTOR signaling...
This study proposes a control method for Remotely Operated Vehicles (ROVs) to actively dock with AUVs, address the limitations of traditional docking and recovery schemes Autonomous Underwater (AUVs), such as restricted maneuverability external disturbances. Firstly, process strategy ROV active AUVs is designed, improving safety. Secondly, Nonlinear Model Predictive Controller (NMPC) based on Gaussian Function Sliding Mode Observer (GFSMO) compensation designed ROV, generating smooth inputs...
Osteomyelitis exhibits bone defects in an inflammatory and acid microenvironment. As a crucial factor this inflammation responses, the macrophage-osteoclast axis is absolutely core to regulate. The research explored shell-core structured biomaterial, consisting of gelatin nanoparticle (GNP) platform loaded with morphogenetic protein 9 (BMP9) coated metal phenolic network (TA-Ce), which exhibited adaptive sensitivity pH values. Extracellularly, it rapidly responded lower pH, achieving...
Dynamic control of underwater vehicle manipulator systems (UVMSs) is the key part intervention tasks. In this paper, we propose an adaptive controller with a disturbance observer that mainly consists two parts: first law estimates changes in center mass (COM) and buoyancy (COB) vehicle, second nonlinear external model uncertainties. To attenuate overestimation problem, damping term introduced to law. The stability proposed method proven on basis Lyapunov theory. We develop three scenarios...
Underwater vehicles with normal thruster configuration methods are unsatisfying in position-keeping tasks because of their limited manoeuvrability. To this end, paper proposes an underwater ve-hicle a novel method and solves the thrust allocation problem by sequential quadratic programming(SQP) algorithm. Comparisons between performance proposed most widely used config-uration given based on UUVSimulator Gazebo. Numerical simulations show that vehicle has better manoeuvrability energy consumption.
Improving the autonomy of underwater interventions by remotely operated vehicles (ROVs) can help mitigate impact communication delays on operational efficiency. Currently, for ROVs usually rely real-time teleoperation or preprogramming operators, which is not only time-consuming and increases cognitive burden operators but also requires extensive specialized programming. Instead, this paper uses intuitive learning from demonstrations (LfD) approach that operator as inputs models trajectory...
