Applying unmanned ground vehicle technologies to unmanned surface vehicles

SPIE Proceedings, 2005
Development of Unmanned Ground Vehicles (UGVs) has been ongoing for decades. Much of the technology developed for UGVs can be applied directly to Unmanned Surface Vehicles (USVs) with little or no modification. SPAWAR Systems Center San Diego (SSC San Diego) has successfully demonstrated this by transitioning technology (both hardware and software ...

Vehicle-following for unmanned surface vehicles

2012
This chapter presents experimental and theoretical issues related to the cooperative path-following of unmanned marine vehicles (UMVs) focusing on the application of vehicle-following and methodological aspects regarding the design of suitable metrics for performance evaluation of the proposed guidance techniques.

Spatial correlation for unmanned surface vehicles

2005 IEEE Antennas and Propagation Society International Symposium, 2005
The paper considers multi-sensor communications between low profile boats, such as unmanned surface vehicles (USVs), in a rough sea environment. We derive the expression of spatial correlation coefficients between two antennas, which is important in designing the configuration of multi-sensor systems.

Obstacle detection for Unmanned Surface Vehicle

2014 International Conference on Electrical Sciences and Technologies in Maghreb (CISTEM), 2014
The goal of this paper is to present a new monocular vision system for obstacle detection to be used by USV (Unmanned Surface Vehicle). This system is based on a monocular camera placed on a known height above the waterline. The technique used to calculate the distance between camera and obstacle depends on earth geometry and requires the prior horizon

Sequential Guidance of Multiple Unmanned Surface Vehicles

2020 39th Chinese Control Conference (CCC), 2020
This paper studies the integrated guidance and control (IGC) algorithm for multiple unmaned surface vehicles (USV). Considering the error of USV dynamic model and the external unknown disturbances, the mathematical model of IGC algorithm is established.

A jellyfish distribution management system using an unmanned aerial vehicle and unmanned surface vehicles

2017 IEEE Underwater Technology (UT), 2017
In this paper, we propose a jellyfish distribution management system using an UAV (unmanned aerial vehicle) and USVs (unmanned surface vehicle). The UAV was designed to satisfy the requirements for flight in ocean environment. The target jellyfish, aurelia aurita, is recognized through a convolution neural network and its distribution is calculated.

Course Control of Unmanned Surface Vehicle

Solid State Phenomena, 2013
The paper considers the problems of controlling a course of an Unmanned Surface Vehicle USV. To select proper course controller, following three methods were tested: PID, slide and fuzzy control. Moreover, to counteract sea current two methods were presented and compared by means of numerical research.
