Roboboat Competition

RoboBoat is an international student competition to design autonomous robotic boats. The robotic boat navigates through the challenge course with impressive maritime maneuverability. This year is the third year for Bengawan UV Roboboat team to compete in the Roboboat competition.

Autonomy Challenge

At the International Roboboat Competition (IRC) 2025, Mandakini Zenith plans to complete all missions in the order of mission completion shown in Figure. Navigation Channel, Mapping Migration Patterns, Race Against Pollution and Return to Home missions will be the first priority to complete. Treacherous Waters will be second priority and Rescue Deliveries will be third priority.

DEVELOPMENT TIMELINE

Historical Records
Of Build Progress

SEPTEMBER

Planning and Strategy Research

Based on team evaluation, discussions and research to develop things that need to be developed from the previous year and prepare strategies to be able to implement IRC 2025 to the fullest. Based on the results of discussions and research, it was decided that the ship would use a symmetrical round hull catamaran hull with the same modularity concept as the previous year but with a higher frame to facilitate travel and a higher frame to help protect components from large waves.

Designing Hull and Simulation

Next, the ship design process is carried out. Stability, resistance and RAO simulations were carried out on the hull and static stress simulations on the frame to get the best hull and frame. Simulations were carried out using Maxsurf, Ansys and Fusion 360 software.

OCTOBER

Hull Manufacturing

Ship manufacturing using fiberglass and gelcoat as the main coating. The manufacture of the hull is carried out with plywood and balsa wood from the design that has been made and analyzed. Then the hull that has been arranged is coated with gelcoat to become a mold and then re-coated with gelcoat and fiberglass to make the hull. After the hull has been made, painting and installation of the frame on the hull is carried out.

Technical Design Report, Video, and Website Development

Our team thoroughly documents the robot's construction, testing, and development phases, creating essential material for the Technical Design Report (TDR), website content, and video production. We also carefully script the submitted video to ensure clarity and professionalism. This comprehensive process highlights our robot's technical excellence while demonstrating our commitment to transparent, high-standard documentation across all competition submissions.

NOVEMBER

Electrical Assembly

The team installed electronic components and propulsion systems on the ship. The placement of the components is precisely organized so that the electronic components are safe from the impact of the waves and can work optimally. An exhaust fan is also installed on the top of the ship to facilitate air circulation and remove heat from the box.

Boat Testing

After the shipbuilding process has been completed, testing of the ship is then carried out. The tests carried out are buoyancy tests to determine the ability of the ship to float when receiving loads from components and propulsion. Then the impact test is also carried out on the ship's frame in holding the hull when subjected to dynamic loads.

DECEMBER-FEBRUARY

Technical Design Report, Video, and Website Final Update

Our team conducts a detailed review and thorough revisions before the final submission. This process involves scrutinizing grammar, refining writing structure, adhering to formatting standards, and correcting inaccuracies in the documentation. By prioritizing clarity, precision, and professionalism, we aim to enhance the overall quality and presentation of our work.

Trial Autonomy Challenge Tasks

After all the testing is done, the team will try to complete the mission on Roboboat 2025 using the ship that has been built.
