-Autonomous Underwater Vehicles (AUVs) are self-propelled robotic platforms that can perform a predetermined mission completely unmanned. A series of manoeuvring experiments were performed using the MUN Explorer AUV during the summer of 2006 and a selection of these experimental results are presented in this paper. The purpose of these experiments was to collect a set of useful data for validating a hydrodynamic model of the dynamic performance of the vehicle. This paper aims at explaining the methods and measures adopted in accomplishing this task. Apart from providing a data set for validation of the hydrodynamic model, the data record also shows the ability of the AUV to perform extreme manoeuvres and the accuracy with which it can follow a pre-planned mission.
Abstract-A series of full-scale zigzag manoeuvring trials were performed using a streamlined Autonomous Underwater Vehicle (AUV) -the MUN Explorer AUV during the summer of 2006. This paper presents the results and observations from the zigzag manoeuvres or the Z-tests performed in horizontal planes. Unlike the conventional method of performing a Z-test, these zigzags were performed by allowing the vehicle to follow a predefined path that was laid out in a zigzag pattern. The paper outlines briefly the method by which these tests were conducted and discusses the observations made.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
