X Square Robot debuts foundation model for robotic butler after $100M Series A - The Robot Report

X Square Robot, a Shenzhen-based startup founded in 2023, has raised $100 million in Series A+ funding and introduced Wall-OSS, an open-source foundational AI model designed for robotic platforms, alongside its Quanta X2 humanoid robot. The company aims to advance household humanoid robotics by addressing key limitations in current robotic AI, such as over-reliance on task-specific training and excessive focus on bipedal locomotion. Instead, X Square Robot emphasizes generalized training in manipulation with robotic hands and reasoning across diverse robot forms to enable robots to perform unpredictable real-world tasks, like serving food, which traditional warehouse-focused training does not prepare them for. Wall-OSS is built on what X Square Robot claims to be the world’s largest embodied intelligence dataset and is designed to overcome challenges like catastrophic forgetting (loss of previously learned knowledge when training on new data) and modal decoupling (misalignment of vision, language, and action). The multimodal model is trained on vision-language-action
