The primary objective of the project was to develop a robust, modular, and hydrodynamically efficient underwater robotic platform capable of performing autonomous navigation and perception tasks in submerged environments.


Key Responsibilities

  • Led the mechanical design and structural architecture of the AUV platform.

  • Designed the waterproof enclosure and sealing mechanisms for sensitive electronic components.

  • Developed the thruster mounting and propulsion layout to ensure stable six-degree-of-freedom motion control underwater.

  • Worked closely with the electronics and software teams to ensure seamless integration of sensors, power systems, and onboard computing units.

  • Oversaw manufacturing, assembly, and mechanical testing of the AUV structure.

  • Optimized the design for hydrodynamic stability, weight distribution, and buoyancy control.


Technologies and Components

  • Aluminum and polymer structural frame

  • Underwater thrusters and propulsion modules

  • Pressure-resistant electronics housing

  • Depth sensors and inertial measurement units (IMU)

  • Onboard computing using embedded systems

Outcome

The developed USV platform served as a testbed for autonomous surface navigation and perception algorithms, enabling the team to develop and test robotic maritime technologies.
