Experimental validation of docking and capture using space robotics testbeds [PDF]

Docking concepts include capture, berthing, and docking. The definitions of these terms, consistent with AIAA, are as follows: (1) capture (grasping)--the use of a manipulator to make initial contact and attachment between transfer vehicle and a platform;

Process‐Based Hydrologic Model Representations of Non‐Perennial Streamflow in the Pacific Northwest, USA

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract There is a global abundance of non‐perennial rivers and streams, of which are predicted to increase due to environmental change and anthropogenic influences. However, most modeled representations of streamflow have been constructed with perennial systems in mind, leaving a gap in our understanding and representation of non‐perennial systems ...

Guideline requirements for serviceable spacecraft grasping/berthing/docking interfaces based on simulations and flight experience (survey paper) [PDF]

As space vehicles and structures become larger and more complex, the development of systems to assist humans in assembling, operating, maintaining, and performing space rescue or retrieval of these vehicles and structures becomes increasingly important ...

Integrating Berthing Plan and Container Transshipment at the Sea‐Rail Intermodal Terminal

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This article integrates the sea‐rail intermodal container transshipment optimization problem with berth planning. A mathematical programming model is formulated and a heuristic solution approach is proposed. The approach demonstrates the potential to reduce overall operational costs and various operational factors are analysed to provide managerial ...

An Improved A-Star Algorithm Considering Water Current, Traffic Separation and Berthing for Vessel Path Planning

Applied Sciences, 2019
A traditional A-Star (A*) algorithm generates an optimal path by minimizing the path cost. For a vessel, factors of path length, obstacle collision risk, traffic separation rule and manoeuvrability restriction should be all taken into account for path ...

A Hybrid A*‐APF Path Planning Method for Ships Entering the Berthing Waters

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper presents a two‐stage hybrid path planning approach for ship berthing: the first stage builds an accurate environmental model based on berth features and the second stage combines an improved A* algorithm (with directional consistency penalty) and the artificial potential field method to generate feasible paths and enhance local obstacle ...

Graph Neural Network‐Enabled Robust AIS/Radar Data Association for Intelligent Monitoring of Ship Safety

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
We propose a graph neural network (GNN)‐enabled robust AIS/radar data association method to address limitations of existing methods, that is, time asynchrony, spatial differences, and environmental noises. Our novel computational method performs well in efficiency and accuracy, and promotes the safety monitoring capabilities of ships in the shipping ...

Design of an adaptive backstepping controller for auto-berthing a cruise ship under wind loads

International Journal of Naval Architecture and Ocean Engineering, 2014
The auto-berthing of a ship requires excellent control for safe accomplishment. Crabbing, which is the pure sway motion of a ship without surge velocity, can be used for this purpose.
