On November 6, Yunshen Technology officially released a new quadruped robot product - Jueying X50. Through a new upgrade of "sensory control fusion" and a high-rigidity and high-response joint system, it achieves a comprehensive breakthrough of greater load, stronger traffic, and more stable posture. Yunshen further expands the boundaries of heavy-duty operations for quadruped robots in extreme environments, solving pain points for high-risk industries such as emergency firefighting and energy and power.

Heavy load and traffic have long been a difficult problem for quadruped robots: as the load increases, the fault tolerance space for climbing and descending steps narrows simultaneously. During high-intensity outdoor operations, robot dogs often get stuck in the "last mile" of complex terrain. According to Leifeng.com (public account: Leifeng.com), the Jueying X50 quadruped robot has comprehensively optimized the joints and overall structure of the robot, increasing the load during continuous travel to 50kg without increasing the size of the body.

Under the rated large load state of 50kg, the Jueying X50 quadruped robot can still move forward stably with load when facing complex road conditions such as stair slopes, rugged mountain roads, and gravel roads. It has all-terrain heavy-load capabilities and is capable of undertaking operations on high-intensity and complex terrains. During power inspections, the Jueying X50 robot dog can carry heavy equipment such as hydraulic tools, insulator strings and grounding wire groups, reducing the burden of manual handling and effectively avoiding safety problems such as physical exhaustion, occupational strain, falls and sprains for maintenance personnel; in firefighting tasks, the Jueying X50 robot dog of Yunshencheng Technology can not only carry tens of kilograms of firefighting equipment It is equipped to quickly penetrate into the fire scene, and can also carry fire hoses to carry out continuous water spraying operations, thereby greatly reducing the risk of firefighters working in close and high-risk operations; in emergency rescue, the Jueying X50 robot dog can carry life detectors, demolition tools, medical supplies and other heavy rescue equipment deep into the disaster scene, reaching the core area of the accident within the golden rescue time.

At the same time, under a rated load of 50kg, this quadruped robot continues to gallop for more than 2 kilometers at a speed of 3m/s. 3m/s, which is approximately the speed of an adult jogging lightly - carrying a 50kg load, it can still run the entire 2 kilometers at the same running pace as when a person is not carrying any weight. This is an all-round test for the entire machine: when traveling at high speed with a heavy load, the impact on the joints is multiplied every time the foot falls, and the power system needs to output high power for a long time without performance degradation. Behind this is the collaborative optimization of the high-rigidity and high-response joint system and the overall machine structure, turning the extreme parameters in the laboratory into normal capabilities that can be sustainably achieved on the job site.

Aiming at complex terrain operations

Standard answers are never prepared for robots at the job site. The spacing between steps varies in size, and there is no unified standard for step height differences. Once the robot dog is loaded with weight and the center of gravity rises, the error-tolerant space for landing will be greatly narrowed - a landing point deviation of a few centimeters may cause a miss or slip, interrupting the mission midway.

How to achieve such collaborative sensing and control capabilities? Jueying X50 integrates lidar point cloud, IMU and other multi-source sensor data in real time, and relies on reinforcement learning motion control algorithms to dynamically predict terrain and plan footholds. With the high-speed response characteristics of highly rigid joints, every judgment on the sensing end can be instantly converted into stable body movements, achieving a close linkage between sensing decision-making and motion execution.

With this set of capabilities, the Jueying X50 quadruped robot can easily cope with various extreme terrain challenges: continuously climbing over 80cm high platforms, continuously crossing stone piers at 70cm intervals, and continuously climbing hollow stairs without risers.

In actual tests, the Jueying X50 quadruped robot can carry inspection equipment and climb up layer by layer on the hollow steel ladder in the boiler workshop of the power plant; it can move steadily between the pipe gallery platforms in the chemical equipment area and climb high-risk structures; in multi-story factory buildings, the Jueying X5 0 The quadruped robot can carry rescue equipment and climb stairs continuously, opening a vertical attack channel for firefighters; between the rubble and broken floors of the ruins, the Jueying X50 quadruped robot can climb over obstacles and cross faults, delivering rescue supplies to depths that are difficult to reach by humans.

Effectively cope with impacts and complex bumpy conditions

Field operations often encounter disturbing conditions such as road bumps, material dragging, and accidental impacts, which can easily cause equipment instability, interrupt tasks, and slow down the overall operating rhythm. The Jueying X50 quadruped robot is equipped with a new generation of posture control algorithm and high-rigidity fast-response joints. It can adjust the body state in real time during movement and continuously maintain body balance. The robot supports flexible configuration of pitch, yaw, and roll angles, and can change its body posture as needed to adapt to diverse operating requirements. It still maintains excellent stability and controllability under sudden disturbances such as push-pull and external impacts, and its action output is precise and controllable, reducing the risk of drift, dumping, and mission abort, and ensuring stable, safe and reliable operations under dynamic and complex working conditions.

The impact resistance and attitude adjustment capabilities are opening up new solutions for close-range fire-fighting operations. The Jueying X50 quadruped robot can dynamically adjust its body posture to offset the recoil reaction caused by high-pressure water spray, accurately lock the direction of the water gun spray, ensure that the jet is stable and controllable, effectively improve the efficiency of fire-fighting operations, and protect personnel safety. In the face of common ruins, messy obstacles at rescue sites, and slight bumps and impacts during operations, the Jueying X50 quadruped robot can quickly self-adapt and correct its posture, maintain smooth operation, uninterrupted operations, and calmly adapt to various high-risk and disorderly operation sites.

Previously, the National Development and Reform Commission made it clear that the robot industry must prevent blindly following the trend and jumping on the bandwagon, and must form a closed loop of application in real scenarios. The launch of the Jueying X50 quadruped robot is Yunshen Technology's systematic response to the actual needs of the industry: it can continuously gallop for 2 kilometers under a 50kg load, integrate sensory control to predict terrain, accurately land on its feet, and adjust its anti-impact attitude to face complex working conditions - each capability corresponds to a real operating pain point.
