The Aquatic Immersive Observation System, or AIOS, is a drone designed for exploring and recording the ocean. It uses a spherical lens system to take immersive 360° videos underwater. The footage can be downloaded and reviewed on any multimedia device, preferably on virtual reality headsets for the most realistic experience. Regardless of the format, AIOS allows anyone will access to a smartphone to have a diver's immersive underwater experience - with no training or risks required.
