<h1>X Square Robot secures $140M to advance embodied AI foundation models and commercial autonomous delivery applications.</h1> X Square Robot closed a Series A++ round raising about US$140 million to accelerate development and commercial deployment of its WALL-A embodied AI foundation model family. WALL-A integrates VLA with World Models and causal inference, using large-scale real-robot reinforcement learning and a model-driven closed-loop of hardware, data capture tools, and processing pipelines. The company released an open-source variant, WALL-OSS, and reports real-world deployments-including autonomous food delivery by the Quanta X1-and is scaling hardware and component production for multi-sector commercial use.
