Technical Background
Embodied AI, as pursued by X Square Robot, revolves around the development of foundation models that enable robots to interpret and interact with dynamic physical environments, drawing parallels to LLMs but extended to incorporate sensory-motor feedback loops for task execution. Founded in December 2023, the company has focused on "robot brain" architectures, exemplified by the WALL-A VLA models, which integrate visual perception, natural language processing, and action planning to achieve generalization in unstructured settings through large-scale reinforcement learning (RL) on real-robot data.
This approach contrasts with simulation-only training paradigms by emphasizing a closed-loop "flywheel" mechanism, wherein hardware interactions generate data that iteratively refines models, thereby enhancing robustness to variables such as environmental noise or object deformations. Core to X Square's technical stack is the WALL-A framework, a vision-language-action foundation model augmented with world models for predictive reasoning, supported by data acquisition tools including teleoperation systems, exoskeletons, and the Universal Manipulation Interface (UMI) for efficient dataset curation. The company has also released WALL-OSS, an open-source variant of these models in September 2025, fostering community-driven advancements in embodied intelligence.
Product offerings center on the Quanta series: the Quanta X1, a wheeled bimanual robot designed for handling complex scenarios involving wind disturbances, deformed objects, or visual occlusions via causal inference algorithms; and the Quanta X2, a wheeled humanoid or semi-humanoid platform extending these capabilities to more anthropomorphic interactions. In-house development of core components—such as robotic arms, joints, and controllers—facilitates mass production readiness, with initial deployments reported in package sorting, food delivery, manufacturing, logistics, and healthcare applications. Revenue streams, though sparsely detailed, include sales to educational institutions, hotels, and retirement homes, indicating early commercial traction beyond industrial pilots.
