Autonomous boat for protection of marine sanctuaries
| Resumo: | This thesis focuses on the development of an autonomous boat capable of carrying out surveillance missions and responding to potential threats within marine sanctuaries. Due to the reduced interior space of the boat, some structural changes were made to it so that more components necessary to carry out this thesis can be added. This structural change is carried out using a 3D printer, with a very common filament, PLA. Some tests, such as temperature tests and ensuring that it is waterproof, are carried out in order to test this material for use. Once the structure is complete, the necessary components are added to control the boat and monitor the environment around it. Components that allow you to control the boat include a boat controller, a Pixhawk 4 mini, a telemetry radio, and a GPS unit. Some temperature and humidity sensors and a camera allow you to monitor the marine environment. The use of renewable energy sources is very important in this type of project because, as it is a boat that monitors the environment, it would be good practice to try to harm it as little as possible. A photovoltaic system is therefore created to charge the boat’s battery while it travels. Some tests were carried out to allow us to know the current consumed by the different components used and the current produced by the photovoltaic panel. Finally, an analysis is made of the efficiency of the various components and what can be improved so that the general efficiency of the boat is better in the future. In order to carry out computer simulations of the boat, several marine hydrodynamic and hydrostatic physics equations were obtained in order to make the most realistic model possible for the boat. Some simulations were carried out using these equations using software Matlab. In these simulations a comparison is made between a route with the obtained model and the same real experimental route carried out in the field as well as the error associated between the speeds and boat positions over time. |
