Low-Cost Unmanned Underwater Vehicle Design

Abstract

Unmanned underwater vehicles have become a tool needed in military, commercial and research review areas. underwater vehicles can take an active role in underwater search and rescue activities to remove objects from underwater and to make repairs with the arms to be mounted. In addition, they can undertake tasks such as target tracking and mapping at low depths with the cameras to be used in the vehicle. In this study, designed two low-cost unmanned underwater vehicles that could be used for missions such as underwater exploration and cleaning. While the number of engines were kept the same in the designed vehicles, two different sequences were used. When starting the design, they were a lot of titles take as a reference such as safety, cost, usability and ease of manufacturing. The designs that were drawn on paper with hand drawing were carefully examined and any negativity such as negligence, error, miscalculation was prevented. The manufactured vehicle has a high mobility in water and can maintain its own balance in water against external factors that may occur. This high mobility was achieved by using a six underwater thrusters. In order to maximize the buoyancy of the vehicle, the materials used in the vehicle were carefully selected. The vehicle chassis is made of Plexiglas and a sealed acrylic tube is used to protect the electronic components. In the front of the chassis, there is a robot arm made of PLA filament material in order to fulfill the planned tasks. While designing the mechanical equipment, the final design was created by considering the static and flow analysis.
