Object Avoidance Onboard An Autonomous Underwater Vehicle In Support Of Geomagnetic Based Navigation System, Eric Benavidez

Electronic Theses and Dissertations 2020 - Present

The objective of this thesis was to collect and analyze magnetic field data in the vicinity of the Mercy, Tracey, and Jay Scutti with an autonomous underwater vehicle (AUV) and a forward mounted magnetometer. The collected data was used to develop geomagnetic contour maps and magnetic thresholds of known anomalies to compare the results with validated sources such as NOAA.

In addition, this collected data was used to develop a Gazebo simulation which accurately modeled the magnetic field data and ocean effects of the Fort Lauderdale Shipwreck Trail. This Gazebo simulation allowed for proper testing and refinement of object avoidance …

Foreign Object Detection System Development Using Edge Devices Integrated With Quadcopter Autonomous Tracking, Chi-Chia Huang, Ching-Hung Lee

Journal of Marine Science and Technology–Taiwan

This study proposes an all-weather autonomous foreign-object detection system capable of operating in low-light environments. We used a highly mobile quadcopter equipped with an edge-computing device as the inspection platform. On the software side, we integrated a low-light image enhancement model, a path-tracking algorithm, and a foreign object detection model to achieve rapid object detection. A lightweight, low-light image-enhancement model reduces the need for additional lighting equipment, thereby enabling reliable detection under low-light conditions. The path-tracking algorithm integrates a lightweight semantic segmentation model with traditional image-processing techniques to establish flight paths efficiently and reliably. The foreign-object detection component employs state-of-the-art …

Mechanical and Civil Engineering Student Publications

Trash pileup in our waters is an increasing problem. Removing floating plastics and debris from our ecosystem would reduce mortality rate of marine animals. Solutions for this already exist but most of them are proprietary and expensive. Therefore, an autonomous, publicly available and cheap alternative was developed to skim and clean the water surface from garbage.

Sensor Updates For Bigheaded Carp-Tracking Autonomous Boat, Jordan Kaufmann

Honors College Theses

Bigheaded carp are an invasive species that overpopulate and compete with the native species of Kentucky Lake as well as many other North American aquatic ecosystems. The movement patterns of Bigheaded carp are being studied nationwide by the United States Geological Survey and multiple universities. These studies ultimately seek to control their spread and reduce or reverse the ecosystem destabilization caused by this invasive species. Such studies are currently conducted manually on Kentucky Lake by graduate students affiliated with the Murray State University (MSU) Biology Department and Hancock Biological Station, and these manual studies are an arduous and time-consuming effort. …

Deep Ocean Vehicle (Dov) Scientific Payload, Nichole "Nikki" T. Arm, Mason Gariepy, Brianna Roberts, Kyle C. Walsh

General Engineering

This report aims to provide technical insight into the Deep Ocean Vehicle project performed by the Barrel Eye Explorers. The project was a part of the 2021-2022 Interdisciplinary Senior Project class at California Polytechnic State University, San Luis Obispo. The team consisted of Nikki Arm, Mason Gariepy, Brianna Roberts, and Kyle Walsh who were engineering students in the Mechanical, Materials, General, and Industrial engineering departments, respectively. This project was sponsored by Dr. Crow White and overseen by Karla Carichner. The project was a continuation of Nikki Arm’s internship with Global Ocean Design during the Summer of 2021. The lander, Deep …

Hydromodus: An Autonomous Underwater Vehicle, Alex Kost, Anu Mahinkanda, Jordan Read

Electrical Engineering

Hydromodus is a student-led multidisciplinary project conceived by Jordan Read designed to provide a low-cost modular hardware and software solution for researchers and scientists. For the scope of the Senior Project class, it is designed to be a baited remote underwater vehicle (BRUV), but the platform is highly modifiable and open-source.
