In the world of underwater exploration and competition, precision, innovation, and teamwork converge to create marvels of engineering. Our autonomous underwater submarine project, designed for the RoboNation RoboSub competition in 2025, exemplifies these qualities. Guided by our dedicated subteams—Mechanical, Electrical, and Autonomy—each brings a depth of expertise and innovative solutions to overcome the unique challenges of underwater robotics.

Mechanical Innovations: Crafting a Robust Framework

The mechanical team’s expertise is foundational to the structural integrity and operational efficiency of our submarine. Utilizing lightweight yet durable aluminum pipes for the frame, the design is tailored for endurance and maneuverability under the immense pressures of deep-water environments. Central to our propulsion system are the BlueRobotics T100 thrusters. These thrusters are meticulously chosen for their robust features: ● Efficient brushless motors and compact design, ensuring high performance in tight spaces. ● Strong UV resistant polycarbonate plastic and high-performance plastic bearings, optimal for corrosive saltwater conditions. ● Counter-rotating propellers that provide stability and reduce the torque effects that can skew navigation underwater. The inclusion of 3D-printed motor mounts showcases our commitment to customized, precise engineering, allowing for optimized positioning and secure mounting of propulsion systems.

Electrical Excellence: Power and Perception

Our electrical subteam ensures that our submarine is not only powered efficiently but also smartly controlled. Central to their efforts are two specialized PCBs:

● Hydrophone Noise Filtering PCB: Enhancing the submarine's auditory capabilities to detect and analyze underwater acoustics with minimal background interference

● Controls PCB: A completed system that orchestrates the flow of power and data between the Nvidia Jetson Orin AGX and the submarine’s propulsion units through the Orange Cube controller

The main components include:

● 8 motors/thrusters

● 8 ESCs

● 2 batteries: 11.1V battery for the Jetson and the motors and a 7.4 V battery for the Orange cube and the servos

● Orange CUBE

● Nvidia Jetson Orin AGX

● Hydrophones

● Camera: ZedX with inbuilt IMU

● 2 servos for smaller subtasks

The submarine is equipped with the ZedX camera, a cutting-edge device for underwater computer vision. This camera is pivotal in performing visual tasks, such as object recognition and navigation aids, crucial for the dynamic and visually complex environments of the RoboSub competition.

Autonomy: Intelligent Navigation and Learning

The Autonomy subteam brings the submarine to life with sophisticated algorithms and software integration. Utilizing ROS2 - Noetic and various rosbags, the team crafts algorithms for autonomous navigation, decision-making, and interaction with the underwater environment.

A custom ROS environment not only supports operational needs but also acts as an educational platform, equipping new team members with the necessary skills and understanding to contribute effectively. This continuous learning environment is vital for maintaining the longevity and innovation of our project.

Preparing for RoboSub 2025

As we prepare for RoboSub 2025, our team remains focused on refining our submarine’s capabilities through rigorous testing and iterative design. The competition not only provides a platform to showcase our technological advancements but also challenges us to push the boundaries of what is possible in autonomous underwater systems.


Our journey towards RoboSub 2025 is filled with challenges, learning, and immense potential. By leveraging the unique skills of our Mechanical, Electrical, and Autonomy teams, and integrating state-of-the-art technologies like the ZedX camera, we are paving the way for future innovations in underwater robotics. We invite the community to engage with us, share insights, and follow our progress as we dive into the depths of innovation and competition. We appreciate your interest and encourage questions and discussions about our project, as each interaction enriches our journey and prepares us better for the challenges ahead.
