Guangdong Tianji Intelligent System Co., Ltd. has completed a RMB 1 billion (~$140M) Series B and Series B+ financing round, reaching a post-money valuation of nearly RMB 10 billion (~$1.4B), with investors including GL Ventures, Meituan Strategic Investment, Tencent, and GGV Capital. The company has an order book exceeding 10,000 humanoid robots from 45 global clients, though the article emphasizes that profitability in robotics depends on product standardization rather than just sales volume, citing Unitree Robotics' RMB 2.78B net profit versus UBTECH's nearly RMB 800M loss as contrasting examples.
X Square Robot has released XRZero-G0, an open-source hardware-software framework designed to address the data bottleneck in embodied AI research. The system includes the G0-Dataset, a 2,000-hour multimodal repository, and is said to reduce real-robot training data requirements by up to 20× under experimental conditions by standardizing robot-free data collection.
A cleaning service in Shenzhen deploys WALL-A robots from X Square Robot in real homes as part of a partnership with 58 Home, where robots work alongside human cleaners. The robot uses an end-to-end Vision-Language-Action model to handle structured cleaning tasks while humans handle decision-making. This represents a practical deployment strategy rather than a laboratory demonstration, operating in actual apartments with pets, children's toys, and clutter.
