Final Project: Mini Autonomous Research Vessel with GPS Navigation Project Summary

This project presents the development of a mini autonomous research vessel capable of navigating on water using a GPS tracking system. The vessel is designed to move accurately between predefined coordinates, making it suitable for basic environmental monitoring and research tasks.

The system integrates embedded electronics, navigation algorithms, and mechanical design to achieve stable and controlled movement.

Project Objectives Design and fabricate a small autonomous boat Implement GPS-based navigation Enable controlled movement between waypoints Ensure stability and correct directional movement on water Test real-world performance and accuracy System Overview

The vessel consists of three main subsystems:

  1. Navigation System GPS module for real-time location tracking Microcontroller to process coordinates Waypoint-based navigation algorithm
  2. Control System Motor drivers to control propulsion

Differential thrust system (left/right motors) for steering Power management system (battery + regulation) 3. Mechanical Design and Fabrication

The full platform of the vessel could not be manufactured as a single piece due to the size limitations of a standard desktop 3D printer. The overall dimensions of the vessel are approximately 75 cm (length), 16 cm (width), and 15 cm (height), which exceeds the printable area.

To solve this issue, the structure was divided into five separate parts. Each part was carefully designed to allow precise alignment and strong assembly after printing.

Special attention was given to the connection system:

Additional joining layers and interfaces were added between parts Parts are assembled using adhesive (glue) and soldering techniques where applicable The design ensures structural rigidity and water resistance after assembly

At the current stage of documentation, only the lower part of the vessel is presented. The upper structure is planned as a future addition and will include protective and functional elements.

Two of the main structural components are designed as floating elements, referred to as pontoons (Pantoons). These elements:

Provide buoyancy and stability Help distribute weight evenly Improve balance during movement in water

This modular design approach makes the vessel easier to fabricate, transport, and repair if needed.
