Design and Testing of a Composite Pressure Hull for Deep Autonomous Underwater Vehicles.
Elkolali, Moustafa; Alcocer, Alex (IEEE Access;Volume: 10, Peer reviewed; Journal article, 2022-08-16)This paper outlines the design and testing process of the hull of a deep small Autonomous Underwater Vehicle (AUV), rated at 2000m depth. Many existing AUV pressure housings use aluminum or other isotropic traditional ... -
Design and Testing of a Miniature Variable Buoyancy System for Underwater Vehicles
Elkolali, Moustafa; Al-Tawil, Ahmed; Alcocer, Alex (IEEE Access;Volume 10, 2022, Peer reviewed; Journal article, 2022-04-18)Buoyancy-driven underwater vehicles are key tools for obtaining data from the ocean. Underwater gliders and profiling floats, equipped with sensors, provide crucial information on ocean processes and climate changes. The ... -
Hydrodynamic parameter optimization for miniature underwater glider wings
Elkolali, Moustafa; Splawski, Wilfried; Carella, Alfredo; Alcocer, Alex (OCEANS;Global Oceans 2020: Singapore – U.S. Gulf Coast, Conference object, 2021)This paper describes the design and optimization of the shape of the wings of “OASYS” research project underwater glider, by maximizing the lift to drag ratio through using computational fluid dynamics. Different wing ... -
A low-cost wave/solar powered unmanned surface vehicle
Elkolali, Moustafa; Al-Tawil, Ahmed; Much, Lennard; Schrader, Ryan; Masset, Olivier; Sayols, Marina; Jenkins, Andrew; Alonso, Sara; Carella, Alfredo; Alcocer, Alex (OCEANS;Global Oceans 2020: Singapore – U.S. Gulf Coast, Conference object, 2021)This paper presents a prototype of a low-cost Unmanned Surface Vehicle (USV) that is operated by wave and solar energy which can be used to minimize the cost of ocean data collection. The current prototype is a compact ... -
Unmanned Aerial System for deployment and recovery of research equipment at sea
Zolich, Artur Piotr; Johansen, Tor Arne; Elkolali, Moustafa; Al-Tawil, Ahmed; Alcocer, Alex (Aerial Robotic Systems Physically Interacting with the Environment (AIRPHARO);2021 Aerial Robotic Systems Physically Interacting with the Environment (AIRPHARO), Conference object, 2021-10-26)In this paper we present details of Miniature Underwater Gliders (MUG) deployment and recovery mechanism using a multirotor Unmanned Aerial Vehicle (UAV). The paper discusses details of MUG localization with computer vision, ...
