R3000 Water Rescue Robot (also known as Intelligent Lifebuoy) is a remotely controllable lifeboat with its own propulsion system. The U-shaped hull, typically integrally molded from robust, high-buoyancy EPP material, provides substantial flotation—enough to tow two adults while maintaining stable operation in water. Equipped with thrusters, batteries, a power control circuit, and a remote control system with a receiver, it can be operated via remote control, GPS/BeiDou satellite positioning, or autonomous navigation modes. This enables the robot to swiftly reach a drowning person or individuals in distress and safely bring them back to shore.
