BengalSub - Autonomous Underwater Vechile
Robotics
As the Mechanical Lead of the BengalSub team, I was responsible for the mechanical design, structural integration, and construction of an autonomous underwater vehicle (AUV) developed for underwater robotics competitions and research applications.
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.
