Overview

Conventional water rescue operations have long faced a persistent dilemma: rescuers are exposed to high risks when entering the water, response times are slow in complex environments, and search efforts in turbid or debris‑filled waters are extremely difficult. Shenzhen Yuhan Technology Co., Ltd. (Yuhan Tech) was founded by international emergency management experts and renowned university scientists, with a mission to integrate large‑scale AI models, robotics, and intelligent systems to deliver end‑to‑end solutions for the emergency rescue sector. Our Smart Water Rescue Solution fundamentally overcomes the limitations of traditional aquatic rescue.

Core Products

Y20 Water Rescue Robot
This is the standard‑issue rescue device for government emergency departments and civilian water rescue organisations. It is suitable for scenarios including scenic waterways, swimming pools, reservoirs, rivers, beaches, yachts, and ferries. Key features:

• Constructed from corrosion‑resistant, UV‑stable HDPE material.

• Detachable grab bars that provide a stable handhold for persons in the water.

• Multiple return modes: one‑key return, signal‑loss return, route backtracking, straight‑line return, and low‑battery auto‑return.

• Dual control: remote control from shore and onboard control, allowing the person in distress to operate the device independently.

• Self‑righting capability – the robot continues normal operation even if overturned.

• High‑visibility yellow flashing fog light for easy identification and positioning in darkness or low‑visibility conditions.

Specifications: 30 m high‑altitude drop capability | 95 min endurance | 32 km/h unloaded speed | 11 km/h load speed | ≤14 kg weight

Yinglong 1 – Flying Life Ring
A next‑generation air‑sea dual‑purpose intelligent rescue device that combines the rapid deployment of a UAV with the buoyancy of a life ring. Features:

• Remote flight, autonomous route flight, and point‑to‑point flight modes for rapid response beyond terrain limitations.

• Beidou satellite positioning with aerial hover capability.

• Low‑battery warning and signal‑loss return for mission safety.

• Route planning and point‑to‑point navigation for precise path control.

Specifications: 440 mm inner ring diameter | 850 mm wheelbase | Level 7 wind resistance | 520 m maximum flight altitude | 10 min flight time | 14 m/s maximum flight speed | IP68 protection rating | Level 2 sea state wave resistance | 1.2 km over‑water communication range | 1 m return accuracy

Yinglong 2 – Flying Lifeboat
A next‑generation rescue device that combines UAV characteristics with water rescue robot advantages. Equipped with four rotor blades, it can fly rapidly to a person in distress, saving critical seconds. Once the person grips the device, its powerful propulsion system tows them to safety.

Specifications: 14 kg weight | 10 km aerial remote control range | 1,100 m over‑water remote control range | 12 m/s maximum unloaded air speed | 4 m/s maximum unloaded water speed | 2 m/s maximum load speed | 10 min air endurance | 30 min water endurance

Key Advantages

• Zero‑Risk Operation: High‑precision long‑range remote control allows rescue personnel to complete all operations from safe positions on shore or embankments, eliminating the need to enter dangerous waters.

• Second‑Response Deployment: Powerful vector propulsion systems enable one‑key takeoff with peak speed from the moment of launch.

• All‑Environment Adaptability: High‑thrust specialised power systems ensure stable operation in rapids, wind‑driven waves, urban flood zones, and even confined spaces such as underground railway tunnels and culverts.

• Intelligent Safety Assurance: GPS positioning, one‑key return, signal‑loss auto‑return, and other smart features guarantee mission safety.

• Multi‑Person Rescue Capacity: A single unit can simultaneously support multiple adult persons in distress.

Application Scenarios

Urban flood rescue, typhoon emergency response, water tourism safety, reservoir and river patrol, port and ferry emergency support, and rail transit hub flood prevention.
