Sonar Module Integration for EMILY Rescue Robot

The goal of this project is to integrate a sonar system into the EMILY rescue boat, enabling it to conduct underwater scanning in search and recovery missions, such as finding submerged vehicles or searching low-visibility waterways that preclude diver assistance. The team chose a Humminbird sonar because of its wide use in rescue and military applications. Hydronalix requested that the team mount a front-facing waterproof camera on the boat to provide a real-time video feed of water level. The sonar and camera were integrated into an adapted version of the boat’s flotation cover. The sonar transducer can be remotely controlled with a linear actuator, which allows the sensor to be removed from the water, eliminating drag on the boat en route to search locations. Live video and sonar feed can be controlled from at least 400 yards away, and boat operators can watch a live sonar feed on personal mobile devices via a downloadable Humminbird application.
