Yuejia Dynamics is a Shenzhen-based embodied-AI robotics company developing four-legged and wheel-legged robots for industrial inspection, rail transit and public-safety work. At the 2026 World Robot Conference, its message was not simply that it had four different robot designs on show. The larger ambition is to prove robots in demanding real-world settings, then replicate a standard package of hardware, payloads, software and inspection workflows at scale.2

Four robots, split between lighter and heavy-duty work
The company’s lineup consists of two product families and four forms: the compact YJ30 quadruped and YJ30W wheel-legged robot, plus the larger YJ30 Max quadruped and heavy-duty YJ30W Max wheel-legged model.
The YJ30 range is positioned as a lightweight, lower-cost option for smaller industrial environments, campus patrols, emergency response and tourism or exhibition use. The Max range is built for greater payloads and stronger environmental protection, with uses including large-scale industrial inspection, firefighting and public-security operations.3

The World Robot Conference exhibitor listing sets out the distinction:
- YJ30/YJ30W: approximately 17.5–20 kg in weight, with 10–12 kg of payload capacity, IP54 dust and water resistance, 1.5–4 hours of operating time depending on battery configuration, and a top speed of 3–5 metres per second.
3
- YJ30 Max/YJ30W Max: approximately 45–55 kg in weight, with 30–35 kg dynamic payload and 50–55 kg static payload, IP67 protection, 3–4.5 hours of operating time, and stable climbing on slopes of up to 50 degrees.
In practical terms, the smaller robots are intended for constrained indoor spaces and broad deployment across campuses or facilities. The larger machines are designed to carry more equipment and withstand tougher conditions in sectors such as power generation and chemicals, as well as fire and security operations.2

Specifications in public materials can vary by model and configuration. In one company interview, the smaller machines were described as having roughly 15 kg of payload capacity, while the official conference listing gives a 10–12 kg range. Until detailed model-by-model datasheets are published, the official published range is the more useful comparison point.2

The product is a robot-plus-inspection system
Yuejia Dynamics presents its machines as mobile platforms that can carry task-specific equipment, not merely as robots that move around. Its inspection systems can combine visual cameras, thermal imaging, gas sensing, multispectral sensing and acoustic detection, collecting site data and feeding it into inspection software for records and results.2
The company says 4G and 5G connectivity allows operators to monitor equipment status and inspection results remotely, and to intervene or adjust a task when necessary. Its World Robot Conference display included a live Shenzhen Metro inspection feed showing thermal imagery, a 3D map and task-status information.2
That approach addresses the full inspection chain: entering a site, collecting evidence, identifying potential faults, retaining traceable records and presenting results for remote personnel to review. For a customer, the purchase is therefore meant to be an operational inspection capability, not just a robot chassis.
Why the Shenzhen Metro deployment matters
The company’s deployment at Qianhaiwan Station on the Shenzhen Metro is its best-known public reference case. Yuejia Dynamics says the robot performs scheduled inspections autonomously, covering passage doors, bins, ticket gates, advertising light boxes, lighting, floors, walls, automated external defibrillators (AEDs) and explosive-ordnance equipment. A camera captures images, which are then analysed in the backend for potential abnormalities.2
The importance of the case is the operating environment. Metro stations require consistent service, reliable coverage and adherence to regular operating schedules. Yuejia Dynamics calls the approach a potentially expandable “Shenzhen Metro model”: first validate the robot, data collection and workflow in one complex, continuously operating setting, then turn that experience into a reusable solution.2
The company has also pointed to inspection in high-voltage and high-temperature power environments, as well as emergency-management applications such as identifying blocked fire routes and improperly stacked materials. Industrial parks, power sites, chemical plants, hospitals, utility tunnels and municipal parks are among the target settings it has named.2
3
“Benchmark first, then standardise and replicate”
A recurring obstacle in commercial robotics is that every customer site can be different, turning projects into costly bespoke engineering jobs. Yuejia Dynamics’ stated approach is to establish a benchmark deployment first, then productise as much as possible: robot configuration, sensors, software, patrol routes, alerting logic and reporting procedures. Sector-specific changes would be kept limited.2
That helps explain why the company maintains four robot variants. Different chassis sizes and movement designs can match different spaces and payload requirements, while the inspection solution above them is intended to be reused. If this model works across metro, power and emergency applications, expansion should rely more on repeatable deployment than on designing every project from scratch.
A 10,000-unit annual-capacity target—not confirmed output
Yuejia Dynamics says it is advancing large-scale production in Shenzhen and aims to reach annual production capacity of 10,000 units by the end of October. That figure is a company target for capacity, not an independently verified shipment total or a confirmed level of production already achieved.2
The idea is to use the Greater Bay Area’s supply-chain and manufacturing base to support larger deployments of proven solutions. Whether the target is reached will still depend on orders, supply-chain execution, product reliability and the company’s ability to reproduce projects in metro, power and emergency settings.
Where embodied AI and humanoids fit in
Yuejia Dynamics says it develops a full technology stack spanning core components, motion control and algorithms, and it describes a “scenario-data-algorithm” loop as central to commercialisation.3 It has also discussed a simulation training platform and eventual humanoid-robot development. The former is intended to reduce the cost of large-scale training and iteration; the latter remains a planned technical extension rather than a mature commercial product line disclosed by the company.
2
For now, its quadruped and wheel-legged robots are the company’s main route to gathering data in real operating environments, building remote-operations experience and testing whether it can manufacture at volume. The key near-term question is less about humanoid-robot promises than whether it can turn a reference project such as Shenzhen Metro into a reliable, repeatable industrial-inspection product.
