  • Publication number: 20240092129
    Abstract: A waterproof UAV that records camera footage while traveling through air and while submerged in water. The UAV alters speed and direction of propellers dependent on the medium that the UAV is traveling through to provide control of the UAV. The propellers are capable of spinning in both directions to enable the UAV to change its depth and orientation in water. A machine learning (ML) model is used to identify humans and objects underwater. A housing coupled to the UAV makes the UAV positively buoyant to float in water and to control buoyancy while submerged.
