Shenzhen startup Yuejia Lingdong deploys quadruped robots in subway and aims to produce 10,000 units

Shenzhen Startup Yuejia Lingdong, founded in July 2025, presented four models of quadruped robots at the World Robotics Conference. The presentation included a live broadcast from a real trial deployment inside the Shenzhen metro system.

Co-founder and CEO Liu Liang stated that the product line includes two large industrial robots capable of handling payloads exceeding 35 kg and featuring IP67 protection for use in power plants and chemical facilities. Additionally, the company has developed smaller wheeled and quadruped devices designed to transport 15 kg indoors. All these models are built on proprietary hardware and utilize in-house algorithms.

The industrial models are equipped with 4G and 5G modules, allowing users to remotely monitor inspection status and adjust tasks from any location. Technical specifications for the industrial devices include the ability to climb an incline of 55 degrees, navigate obstacles up to 60 cm high, ascend stairs between 20–30 cm high, and operate for four to five hours.

The most notable example of implementation is the use of a dog robot in the Shenzhen metro. This robot automatically patrols the Qianhaiwan station every two hours, seven days a week, checking turnstiles, escalators, lighting fixtures, and fire protection equipment, while the artificial intelligence model detects any anomalies. Liu noted that this is the first quadruped inspection robot regularly operated in Chinese metro systems, and the project successfully passed full-scenario validation before wider deployment.

The company's strategy is based on 'benchmarking first, then standardization and mass production,' using the Shenzhen metro model as a benchmark. Other application areas include inspections at hazardous unmanned sites of China Resources Power, as well as public safety pilot projects with Shenzhen emergency services to detect hazards such as blocked fire lanes.

Production is ramping up in the Greater Bay Area, and the company aims to achieve an annual production capacity of 10,000 units by the end of October. These robots are intended for metro needs, as well as standard energy and emergency service requirements. Yuejia Lingdong's embodied AI training and simulation platform allows for large-scale parallel training with relatively modest computational costs, costing about one-fifth of competitors'. The firm is currently preparing to develop humanoid robot technologies.

Beijing Exhibition Reveals Diversity of Chinese Robotics Industry, Focused on Humanoids and Industrial Applications

At the World Robot Conference 2026, held in Beijing, China, robots demonstrated various functionalities, ranging from fighting and acrobatic dancing to baggage transport, facility inspection, surgical assistance, and household chores. The event took place between August 19th and 23rd and gathered over 300 companies, exhibiting more than 2,000 items and presenting over 150 new releases.

The vast range of exhibited machines illustrates the scale of the Chinese robotics industry. According to the International Federation of Robotics (IFR), China accounted for 54% of global industrial robot installations in 2024, totaling 295,045 units. Furthermore, the country held the world's largest stock of operational industrial robots that year, amounting to 2.027 million.

China's leadership is also notable in the humanoid sector. According to the consultancy Smart Analytics Global, approximately 19,100 humanoid robots were shipped globally in the first half of 2026, with Chinese manufacturers responsible for over 97% of this volume. During the same period, the companies AgiBot and Unitree concentrated about 75% of international shipments.

LimX Luna

Humanoids attracted significant attention during the conference. Unitree, for instance, presented machines in Beijing capable of participating in boxing, dancing, and table tennis demonstrations, integrating movements that require balance, coordination, and varied body control. This performance is not new for the company; in 2025, Unitree humanoid models competed in boxing, showcasing attacks, defenses, and recovery after falls.

The LimX Luna model, from LimX Dynamics, focuses more on performances. Standing at 1.60 meters tall and having 27 degrees of freedom, it executes jumps and splits, combining these physical skills with voice interaction, gestures, and movement imitation. The platform allows for the coordination of over 200 robots for simultaneous performances, featuring distinct choreographies or synchronized movements. The company has also created a tool that integrates dance, movement, voice, and vision to create shows without the need for individual programming of each action.

Kengo, from Galaxea, stands at 1.40 meters and has a bipedal structure. Developed for high-dynamic movements, the robot can replicate actions of greater complexity. In addition to demonstrations, Galaxea aims to apply Kengo in industrial, commercial, entertainment, and companionship contexts. An external source mentioned that robots are evolving from basic tools to form the real-world workforce.

Another humanoid highlight is the MagicBot X1, from Magic Atom. This model features 31 degrees of freedom and was designed to walk, handle objects, interact, and operate in various environments. Intended uses include inspection, manufacturing, logistics, security, reception, and entertainment. The X1 was also seen in demonstrations exceeding simple walking, such as playing table tennis, dunking in basketball, and performing fencing moves.

The fair demonstrated that Chinese robotics is not limited to humanoids capable of mimicking human actions. There are also robots created for specific functions, where factors such as size, safety, or mobility are more relevant than aesthetics.

RealBOT S2

The RealBOT S2, from RealMan, was specifically designed for small-space logistical and industrial environments. It has the capability to lower its body to about 30 centimeters from the ground, allowing it to pick up items on the floor and access low areas. The design also prioritizes locomotion in narrow corridors and between close structures.

In another example, the Kirin, from Kepler Robotics, is a large quadruped intended for cargo transport and outdoor activities. This robot can support a load of nearly one ton, operate for up to eight hours under weight, and navigate inclined terrain, overcoming ramps up to 45 degrees.

Concerns about hazardous environments are highlighted by machines built for inspection. One of the quadrupeds presented at the conference features an explosion-proof design and is made to operate in oil and gas facilities, petrochemical plants, and other locations where a spark or inadequate equipment poses a danger.

Firefighting machines were also shown. One of these models is designed to advance in buildings, warehouses, confined spaces, and debris areas, carrying equipment to locations with high temperatures, toxic substances, or risk of collapse. Additionally, there are more niche applications, such as robots for checking electrical installations, maintaining structures, and moving loads. The logic here differs from initial humanoids: each machine is adapted to the working conditions, rather than trying to replicate the human body.

Specialization extends to healthcare. The ROPA6, from Beijing Changmugu Medical Technology, was developed for various areas of orthopedic surgery, covering hip, knee, unicameral procedures, spine, trauma, and sports medicine. The system received Class III medical device registration in China in 2026. The company also presents it as an integrated platform for multiple orthopedic procedures, rather than isolated equipment for each type of surgery.

In the educational field, UBTECH introduced the TutorC, a robot designed to function as a school assistant. This machine can participate in explanations, presentations, Q&A sessions, and interactive activities with students, in addition to assisting with standardized tasks. The proposal ensures that the teacher maintains control over the activities, being able to interrupt, modify the content, or take over operation while the system executes actions predefined by the class instructor.

In the domestic sphere, variety is also growing. The Vbot, from Vita Dynamics, was created to understand commands and the environment, performing tasks such as picking up and putting away objects, tidying surfaces, and operating appliances. The company also foresees its use in daily care, interaction with the elderly and children, and remote assistance.

Another example is the Simbot, from Beijing Shenpu Intelligent Technology. Unlike having legs, this robot uses a wheel-based base attached to articulated arms. Its purpose is to manage household tasks involving picking up, transporting, depositing, and manipulating objects. The Simbot has 23 degrees of freedom in its body and seven in each arm, along with vision, tactile, force, and language capabilities, aiming to adapt the machine to different residential activities.

The diversity of domestic projects suggests that there is no single concept of a residential robot; there are machines focused on manipulation, others on interaction, companionship systems, and equipment for assisting in specific tasks.

A less visible aspect of the fair includes equipment that does not have the shape of a complete robot, such as robotic hands, sensors, 3D cameras, LiDARs, motors, encoders, articulation modules, actuators, chips, and software. The Linker Hand O30, for example, is a robotic hand with 20 active and independent degrees of freedom. Such components are crucial for tasks requiring finger precision, force control, and varied object manipulation.

There are also perception-dedicated technologies, such as depth cameras, tactile sensors, and measurement systems, which help robots recognize objects and understand their surroundings. These technologies are what allow a command or visual information to be converted into a physical action. Embodied Artificial Intelligence (Embodied AI) is another important front, seeking to link AI models to the physical capabilities of machines. The exhibition gathers platforms for data collection, simulation, training, and movement development, alongside systems that combine vision, language, and control.

The quantity of technologies gathered in Beijing demonstrates that the industry transcends the dancing or fighting humanoid. There is a complete chain behind these machines, involving companies that work on components, software, perception systems, movement, and specific applications. In this landscape, China holds an extremely strong position, being the world's largest market for industrial robots and responsible for the largest share of global humanoid shipments registered in the first half of 2026. The World Robot Conference serves as a showcase for this breadth, displaying robots to attract attention, but also machines designed for factories, hospitals, airports, schools, homes, and hazardous environments.
