HydronContest Bi-Foiler

As part of the hydronContest student race, we designed and built a bi-foiler boat. The goal of the race was to design the most efficient boat able to carry a 20kg weight over a defined track. Choosing a foiling boat architecture was crucial to achieve that goal and win the race.

To control the boat’s attitude, we used the PX4 open source flight controller software to control two flaps located on the main foil. This allowed us to control the roll and flight altitude of the boat. A servo motor allowed to change the rake of the back foil during flight.

My role in the project was to design the mechatronics aspects. This included actuating the control surfaces using the flight controller, designing the data acquisition (Attitude, current, voltage, speed), the telemetry and first person view setup.
