China’s humanoid-robot bottleneck is increasingly a data problem rather than a hardware problem. Robots can walk, dance or complete carefully prepared demonstrations, but dependable autonomy requires something harder to obtain: lawful, diverse, high-quality records of machines sensing, moving, making contact, failing and recovering in the physical world. 5

The 2026 World Robot Conference made that shift visible. Alongside polished robot demonstrations, exhibitors highlighted teleoperation equipment, wearable motion capture, tactile and force-sensing systems, and infrastructure designed to collect the training data that robot-learning models need. 4

The physical-AI data gap
Industry figures cited around WRC put the available compliant real-world physical-interaction dataset at roughly 500,000 hours, while commercially useful general-purpose embodied models are often associated with a requirement for tens of millions of hours. That implies a shortfall of more than 99%—but it should be treated as an industry estimate, not a universal scientific threshold. The quantity required depends on the task, robot platform, operating environment and safety standard. 3

The comparison is important because physical interaction data is not interchangeable with ordinary internet-scale data. A video may show a person picking up a cup, but it normally does not capture the robot’s joint state, grip force, contact timing, friction, slippage or corrective motion. Those details determine whether a robot can repeat the action when the cup is heavier, the surface is wet or the object is positioned differently.
Why demonstrations do not prove autonomy
A scripted routine can hide the hardest parts of robotics. The objects, lighting, path and timing may be controlled, while a human operator intervenes whenever the robot encounters an unexpected condition. The result may look autonomous without demonstrating that the robot has learned a robust perception-to-action policy.
Commercial deployment demands more. Robots must handle variation in object shape, grasp points, surfaces, clutter and surrounding people. They also need to recognize errors and recover from them. In contact-rich tasks, the useful record is not simply whether the final goal was reached; it includes the sequence of observations, actions, physical states and corrections along the way. Purpose-built physical-AI datasets are therefore designed to connect multimodal observations with actions and their consequences. 33

Data collection is becoming more demanding
Early robot-learning datasets could focus on short, repeatable demonstrations. The next phase involves longer tasks with multiple steps and frequent physical contact: manipulation, sorting, assembly, packaging, cleaning and other work in homes, stores, factories and service environments.
That raises the data burden in three ways:
- More variation: the same task must be recorded across objects, layouts, materials and environmental conditions.
- More failure information: slips, collisions, failed grasps and recovery attempts can be as informative as successful demonstrations.
33
- More synchronized signals: cameras, depth, robot pose, joint movement, force, touch and other sensor streams must be aligned so models can learn how perception relates to action.
The scale-up is difficult because real robots are expensive to operate, physical experiments require safety controls, and high-quality data must be curated rather than merely accumulated. A large video archive is not automatically a useful robot-training dataset.
The emerging data-supply layer
Specialist training providers are beginning to fill the gap between human behavior and machine-ready data. Their work can include recruiting and training operators, teleoperating robots, capturing human motion, instrumenting tasks, synchronizing sensor streams, filtering poor trajectories and formatting the results for model developers.
Teleoperation is valuable because it records actions on a real robot rather than only showing a human performing an analogous movement. VR and other generic controllers can provide robot commands, while wearable systems and motion-capture equipment capture higher-dimensional movement from a person and retarget it to a machine. 1
This creates a new supply layer for embodied AI: companies are not only building robot bodies and models, but also producing the demonstrations and sensor records that connect the two. WRC exhibitors explicitly presented data collection as part of the embodied-intelligence stack, including systems that capture head and hand movements during everyday activities. 4

Why China is building nationwide training grounds
Training grounds provide controlled but realistic environments in which robots can be trained, tested and compared. They can reproduce settings such as factories, warehouses, homes, commercial spaces and public-service locations, giving developers access to repeatable scenarios without reducing the problem to a laboratory routine.
According to reporting on a 2026 China Academy of Information and Communications Technology report, more than 70 embodied-AI training grounds were operational nationwide by the end of June, while 46 more were under construction or planned. The sites covered more than half of China’s provincial-level regions; industrial manufacturing was the most common application, appearing in 86% of the reported grounds. 18

The infrastructure matters only if it is actively used. Its purpose is to become a data resource and real-world testing platform, not simply another collection of demonstration venues. In practical terms, the intended loop is: real-world training produces data, data improves the model, improved models support broader deployment, and deployment generates more operational data. 14

Policy is pushing robots out of the demo hall
China’s Ministry of Industry and Information Technology and the State-owned Assets Supervision and Administration Commission launched a 2026 special action for real-world training of humanoid robots and embodied AI. The program focuses on industrial, service and specialized scenarios, including manufacturing, logistics, healthcare, public services and emergency work. 24
25
A government notice described goals including the commercial rollout of 10,000 humanoid robots and more than 100 high-value application scenarios by the end of 2026. 26 The policy approach is to make deployment itself part of the training infrastructure: local governments and state-owned enterprises are encouraged to provide settings where systems can be tested, validated and improved in operational conditions.
24
That does not guarantee that the robots will meet those targets or become broadly autonomous. It does show that the policy emphasis is moving beyond hardware production and toward the data-and-deployment loop required for commercial reliability.
Why robots need more than video, text or driving data
Video and language remain useful. They can teach models what objects are, what instructions mean and what a human action looks like. Simulation can provide scale and help cover scenarios that would be costly or dangerous to reproduce physically. Research on embodied-data standards likewise points toward combining real-world data, simulation and multiple sensory modalities rather than relying on one source alone. 2
32
But these sources do not fully specify the control problem. For manipulation, a robot may need to estimate:
- the object’s position and orientation in three dimensions;
- its own joint angles, velocity and mechanical response;
- the force required to grasp, push, insert or lift;
- the timing of contact, slip or collision; and
- how to adjust when the expected motion does not work.
That is why several collection methods are complementary:
- VR teleoperation records a person’s demonstrated commands through an interface that can be mapped to a robot’s movements.
1
- Wearable motion capture captures human body, arm and hand intent, which can then be retargeted to a robot.
- Force feedback and tactile sensing expose contact, resistance, pressure and slippage that ordinary pixels may miss.
7
- Motor-torque and proprioceptive data reveal the robot’s internal state and how its mechanism responds during an action.
39
- Real-robot trajectories expose calibration errors, latency, sensor noise, mechanical limits and environmental messiness that human video or simulation can only approximate.
34
Autonomous-driving datasets can help with perception and navigation, but dexterous manipulation involves a different action space. Driving is largely vehicle-centric and avoids continuous contact with most objects; tasks such as grasping, insertion and assembly depend on contact forces, compliance and recovery.
The strategic implication
The lesson from WRC 2026 is not that China has stopped caring about robot hardware. It is that hardware alone cannot close the autonomy gap. The competitive advantage may increasingly belong to organizations that can collect, standardize and legally use large volumes of multimodal physical-interaction data.
For China’s humanoid-robot industry, the path beyond stage demonstrations and remote-controlled machines runs through a difficult combination of real deployments, trained operators, instrumented environments, shared data standards and repeated testing. The industry is building that pipeline—but the gap between hundreds of thousands of hours and the tens of millions often discussed for commercialization remains the central constraint. 3
