The 3-degree-of-freedom spherical cage drone is an RF-controlled, highly maneuverable UAV designed for inspection, monitoring, and mapping applications. Its spherical cage design provides robust protection, allowing it to safely navigate through confined or risky environments. The drone features an onboard 4K camera for high-resolution, real-time video streaming, making it ideal for detailed inspections. Additionally, it is equipped with LIDAR for Simultaneous Localization and Mapping (SLAM), enabling precise 3D mapping and autonomous navigation. With RF control, the drone can be operated from a distance, while its real-time visualization capability, powered by Google integration, offers live data feedback for immediate decision-making. This drone is perfect for applications in industries like infrastructure maintenance, surveying, and environmental monitoring.
