AI, Data & Privacy

Caution - data processed in China

This robot sends data to cloud servers in China. For EU residents, this represents a significant data protection consideration. China's data protection framework differs substantially from GDPR, and data transferred there is subject to Chinese law. EU residents should carefully evaluate whether adequate safeguards are in place before using this product.

How to keep it private

Needs internet
Offline

Walker S2 relies on cloud-based BrainNet 2.0 for cognitive functions, task planning, and multi-robot coordination. On-device Intel Core i7 and NVIDIA Jetson AGX Orin handle real-time motor control and local perception. The robot requires cloud connectivity for swarm intelligence and fleet management features.

Available privacy controls

Enterprise fleet management

Industrial customers manage data access through UBTECH BrainNet 2.0 fleet management platform

Force limiting and safety systems

Physical safety controls including collision avoidance and emergency stop for human-robot interaction zones

Privacy tip

Walker S2 is an enterprise industrial robot, not a consumer product. Data handling is managed through enterprise agreements with UBTECH. The robot collects environmental and operational data for fleet coordination via BrainNet. Inquire with UBTECH about data residency, retention policies, and on-premise deployment options before purchasing. Cloud data is processed on China-based servers.

UBTECH spent a decade making toy robots before pivoting to industrial humanoids. Now it has 1,000 Walker S2 units deployed, 800 million yuan in orders, and a Shenzhen factory targeting 5,000 units by end of 2026. The company's evolution from consumer gadgets to factory-floor machines is one of the most underreported scaling stories in robotics.

The alarm goes off at 5:15 AM. By 6:00 AM, fourteen humanoid robots and forty-seven human workers share the same factory floor for an eight-hour shift. This is what that shift actually looks like, hour by hour, drawn from reported deployments at Amazon, BYD, NIO, and BMW. The future of work is not coming. It arrived on a loading dock at 4 AM and spent ninety minutes calibrating its wrist actuators.
