ERON: A PID controlled autonomous surface vessel

2016 18th Mediterranean Electrotechnical Conference (MELECON), 2016
Aquatic unmanned robotic systems have gained popularity due to their abilities to perform a wide range of applications at low cost and no risk to human lives. This research investigates the development of the navigation system of “HPftN”, an Autonomous Surface Vehicle (ASV).

Visual Servoed Autonomous Landing on a Surface Vessel

OCEANS 2019 - Marseille, 2019
In this paper, we describe a quadrotor able to land autonomously on a moving platform by employing on-board sensors. The full pose of the platform is estimated using a vision system. Furthermore, an ultrasonic sensor is used to compute the relative vertical position and velocity of the platform w.r.t. the quadrotor.

Adaptive sliding mode control for autonomous surface vessel

2011 IEEE International Conference on Mechatronics, 2011
An adaptive sliding mode control law is presented and simulation is done for trajectory tracking of an underactuated autonomous surface vessel. The control law is developed by introducing two second order sliding surfaces, first in terms of surge tracking errors and the second in terms of lateral motion tracking errors.

Stereo vision–based navigation for autonomous surface vessels

Journal of Field Robotics, 2010
AbstractThis paper describes a stereo vision–based system for autonomous navigation in maritime environments. The system consists of two key components. The Hammerhead vision system detects geometric hazards (i.e., objects above the waterline) and generates both grid‐based hazard maps and discrete contact lists (objects with position and velocity).

Adaptive shorelines detection for autonomous surface vessel navigation

2013 IEEE International Conference on Control System, Computing and Engineering, 2013
Shorelines and water surface recognition are fundamental cues for ASV navigating in a river. In this paper we present an adaptive shorelines detection approach which is combination of feature-based and edge based method. Firstly, the river boundary is extracted adaptively by color segmentation with a sampling patch.

Design of an Acoustic-Homing Autonomous Surface Vessel

OCEANS 2006, 2006
We designed, built, and conducted trials on an acoustic-homing autonomous surface vessel. After characterizing the performance of a commercially available kayak hull, we installed power, propulsion, and control systems for autonomous operation. The acoustic tracking payload was built up from basic components.

Motion Planning, Guidance and Control System for Autonomous Surface Vessel

Volume 11B: Honoring Symposium for Professor Carlos Guedes Soares on Marine Technology and Ocean Engineering, 2018
This paper presents a motion planning, guidance and control system for an Autonomous surface vessel in a practical maritime environment. The motion planning algorithm is based in the angle-guidance fast marching square method and the guidance system is based in the line-of-sight trajectory tracking algorithm.

Improving Evaluation Methodology for Autonomous Surface Vessel COLREGS Compliance

OCEANS 2019 - Marseille, 2019
This article presents methodology for evaluating the performance of black box autonomous surface vessel (ASV) software, with particular focus placed on determining COLREGS compliance in the presence of competing priorities. The approach utilizes adaptive sampling and unsupervised clustering to automatically identify failure modes and performance ...

Modeling and Visual Navigation of Autonomous Surface Vessels

2015
In this chapter, the authors address main issues of Navigation, Guidance, and Control (NGC) and vision system of Autonomous Surface Vessels (ASV). These issues compose research problems and related research findings in recent years. Related research results are reviewed first; then the hardware and subsystem of ASVs is introduced.
