So, what kind of underwater robot is more suitable for emergency rescue?

Compact & Rapid Deployment

Lightweight underwater robots are suitable for rapid deployment tasks, easy to carry even with small-sized rubber boats or speedboats. They need to be quickly deployed and immediately dive into the water for search and rescue operations upon arrival at the destination. QYSEA FIFISH lightweight rescue underwater robot is compact, only the size of a 17-inch laptop, weighing only 5.7kg, with significant advantages in portability. With just 3 steps, it can be quickly deployed underwater in 20 seconds, and emergency tasks cannot be delayed. In the face of emergency rescue environments, compared with traditional small and medium-sized frame-type underwater robots, the FIFISH lightweight rescue underwater robot can be easily carried, deployed, and operated by a single person, greatly improving emergency rescue efficiency.

Easy Operation & Intuitive Interface

Underwater robots with simple and easy-to-use controls enable rescue personnel to quickly master various functions and operate proficiently, thus saving time during underwater rescue operations. Intuitive and comprehensive underwater data can help rescue personnel quickly grasp the underwater situation, providing detailed data support for rescue operations, making rescue operations simple and efficient. The operation logic of QYSEA FIFISH lightweight rescue underwater robot is simple and clear, supporting various gestures such as American, and Japanese hands, with low learning costs and fast operation. The FIFISH APP can also intuitively display underwater data such as depth, speed, water temperature, and orientation, with a clear and understandable interface, helping rescue personnel better perform underwater tasks.

Robust Stability in Water Currents

During underwater search and rescue operations, various environmental conditions in different water bodies are often encountered. Many rivers and lakes have fast water flow, and underwater eddies become important factors affecting rescue operations. Divers are endangered by underwater eddies during diving operations, and underwater robots with weak resistance to currents cannot maintain stability in such environments and cannot perform operations. Therefore, it is necessary to use the powerful current-resistant FIFISH lightweight rescue underwater robot, which has strong power and stability, can resist up to 3 knots of water flow, and can dive to a maximum depth of 200 meters. Its operating range and resistance to currents can meet the needs of most lakes, rivers, and nearshore search and rescue operations, ensuring stable underwater operations.

Imaging Sonar for Murky Water Search

In the common waters, low visibility greatly affects the efficiency of rescue operations. The FIFISH lightweight rescue underwater robot can be equipped with a 2D imaging sonar system, which can intuitively and quickly display underwater sonar images on the APP. Combined with the onboard camera, in murky underwater scenes, it can quickly search over a large area, investigate suspicious targets, accurately navigate, and lock in the search and rescue target location, greatly improving the success rate of rescue operations.

Wide Reconnaissance Scope & Bright Lighting

For underwater wide-area searches, higher-quality images and a broader camera perspective are needed to improve search efficiency. Moreover, in deeper waters or when night falls, brighter supplementary lights are needed to continue search tasks. The FIFISH lightweight rescue underwater robot is equipped with a 4K ultra-high-resolution underwater camera and has the widest industry-standard 146° ultra-wide-angle underwater field of view, which can obtain a wider field of view at the same time. In terms of lighting, it is also equipped with a 10,000 lumens ultra-bright wide-angle supplementary light, which can easily illuminate dark underwater environments, leaving no suspicious targets unturned and accurately grasping underwater information in real-time.

Long Endurance & Quick Battery Swap

Water rescue often requires long-time and large-area searches. The FIFISH lightweight rescue underwater robot has the industry's first dual-battery hot-swappable design. The dual external batteries can be hot-swapped, without shutting down and restarting, and can be replaced and returned to full power in as fast as 10 seconds. In long-term underwater emergency rescue operations, a single FIFISH lightweight rescue underwater robot is equipped with two sets of batteries, paired with QYSEA's intelligent battery steward for onshore charging, which can be charged to 90% capacity in as fast as 50 minutes, enabling two sets of batteries to be alternately used, greatly increasing the endurance time for emergency rescue operations.

Flexible Mechanical Arm for Strong Grip

Due to the complex rescue environment of rivers, lakes, and seas, and the impact of water flow erosion, once a target is found, it needs to be quickly grasped to prevent it from being washed away, affecting the efficiency of rescue. The FIFISH lightweight rescue underwater robot can be equipped with powerful mechanical arms, including two-claw mechanical arms, three-claw mechanical arms, salvage locks, and other rescue and salvage accessories to choose from. The maximum gripping force of the mechanical arm can reach 10kgf, with robust and durable quality, coupled with the full 360-degree control posture of the body and the ability to pull a 70kg zero-buoyancy Kevlar material cable, it can adapt to various environments and conduct immediate salvage tasks.

Collaborative Underwater Operations

In emergency rescue tasks, underwater robots are often used to locate target objects, and divers follow the underwater cable to find the target object and carry out salvage tasks. In major underwater emergency rescue situations, real-time underwater conditions need to be transmitted back to the command center for the next decision. The FIFISH lightweight rescue underwater robot is designed for lithium battery power supply, not direct power supply mode, so divers can work with underwater robots without worrying about the risk of electric leakage causing secondary disasters. After the underwater robot finds the target object, it can use the AI visual locking function to lock the target object, automatically maintain a stable anti-flow posture, and keep the target object within sight. At this time, divers can dive along the zero-buoyancy cable to the target location. In major rescue tasks such as buses and cars falling into the water, the FIFISH lightweight rescue underwater robot can activate the AI diver tracking function, automatically track the divers engaged in underwater salvage operations in real-time, and transmit the underwater situation back to the command center, escorting the safety of divers' lives and providing more time for underwater rescue decision-making.

AI-Driven Rescue Facilitation

Nowadays, it is an era of rapid development of AI, and AI is gradually changing our lives. AI can free up the hands of operators of underwater robots, making the operation of emergency rescue tasks easier and more efficient. QYSEA Technology has introduced two major functions of AI visual hovering lock and AI diver tracking for the first time in emergency scenarios, enabling efficient collaborative operations with divers. In addition, it has also introduced the U-INS inertial navigation system, which uses AI algorithms to calculate the trajectory of the underwater robot's movement, visually displays it, and allows operators to control the robot without being troubled by complex underwater headings. At the same time, QYSEA Technology has upgraded its independently developed U-QPS 2.0 underwater rapid positioning system, which intuitively displays maps and has dual RTK ship positioning modes. Rescue personnel can achieve accurate positioning even on floating rubber boats or speedboats, and can also use AI 3D path planning function to plan underwater 3D search paths on the APP, enabling the underwater robot to autonomously plan operations, conduct high-frequency and repetitive underwater carpet-like searches in designated waters, and improve search and rescue efficiency.
