ARIVIA Water-Surface Drone is the world’s first autonomous buoy-type water-surface drone equipped with both programmable LED lighting and controllable fountain jets, designed specifically for delivering large-scale water-based entertainment alongside environmental applications. It seamlessly integrates LED illumination, precision fountain systems, GPS navigation, and a powerful onboard audio unit. Multiple units can be synchronized to instantly transform any water surface—such as harbors, resorts, tourist landmarks, or pools—into a choreographed performance stage. ARIVIA can operate individually or in coordinated fleets, enabling dynamic, visually striking light-and-water shows. Future enhancements may include laser projection, mist effects, underwater lighting, and scent dispersion to create immersive, multi-sensory experiences. Beyond entertainment, ARIVIA supports regional revitalization, tourism promotion, and environmental monitoring by capturing real-time data such as water temperature, turbidity, and oxygen levels. Its modular design, durable waterproof housing, and advanced remote operation capabilities make it adaptable for both short-term events and long-term installations in diverse aquatic environments worldwide.
