X Square Robot commits to deploying WALL-B powered robots into volunteer homes by May 26, openly admits they will make mistakes
X Square Robot just held a press conference announcing that their new generation robots, powered by a new foundation model called WALL-B, will physically move into volunteer households on May 26, 2026. That is 35 days from the announcement.
What caught my attention is how the CEO framed the whole thing. He was completely upfront that the robots are at an "intern" stage. They will put slippers in the wrong room. They will stop mid task to "think." They will need remote assistance. But they work around the clock and learn from every mistake in real time.
The technical claim behind WALL-B is a shift from VLA architecture to what they call a World Unified Model (WUM). Instead of separate vision, language, and action modules passing data between each other sequentially, WUM trains all modalities jointly from scratch in a single network. They compare it to Apple Silicon's unified memory replacing the old CPU/GPU/RAM separation. The stated result is that the robot can perceive physics (gravity, inertia, friction), predict what will happen next (a plate hanging off a table edge will fall), and adjust strategy on failure without being retrained by an engineer.
They also talked about their data strategy. Their CTO drew a distinction between "sugar water data" collected in clean lab environments and "milk data" from real homes with cats knocking things over, random clutter, and variable lighting. They have apparently been collecting data across hundreds of volunteer households to train the model on genuinely messy conditions.
On the privacy side, they announced on device visual masking so raw images never leave the robot, explicit opt in consent required before the robot powers on, and no third party data sharing.
The full technical details are supposed to drop at the Guangdong Province AI Application Summit on April 27. Applications to become a volunteer household are open now through their official channels.
