FAQ

What is X Square Robot's core technology?

The company's WALL family of embodied AI foundation models is built on a World Unified Model architecture that combines perception, language, action and physical prediction within a single network. This approach is intended to improve multimodal understanding, spatial reasoning and zero-shot generalisation, enabling robots to perform previously unseen tasks in unfamiliar environments.

How does X Square Robot's data collection differ from existing robotics methods?

The company's QUANXTA Zero Series platform integrates data collection, synchronisation, automated cleaning, intelligent annotation, model training and evaluation into a single closed-loop system. The flagship QUANXTA Zero G1 can reach nearly 100 demonstrations per hour—more than double the efficiency of conventional teleoperation methods—while incorporating automated downstream annotation and sensor synchronisation within one millisecond.

Where are X Square Robot's robots already being deployed?

The company has launched an AI-powered household cleaning service in Shenzhen and Beijing in partnership with 58.com, introduced the 'X Family Member Program' allowing robots to live with families, and entered a strategic partnership with a senior living provider to deploy embodied robots capable of delivering items and assisting with cleaning in elderly care settings.
