The UBTECH Walker S1 is an industrial humanoid robot leveraging full-stack humanoid robotics technologies with embodied intelligence for generalized industrial tasks. It uses a large language model for general task planning with advanced intention understanding and task planning capabilities ranked among the first tier globally. Semantic VSLAM navigation tightly couples semantic perception with traditional VSLAM in a two-stage approach, improving spatial understanding for industrial generalization. An end-to-end learning-based whole-body motion control framework integrating perception and control enables dexterous manipulation and stable walking for complex non-structured industrial tasks. It addresses three key industrial challenges: visual positioning under varying lighting and environmental conditions, motion control under dynamic high-load conditions, and joint cooling during long-term high-load operation. Walker S1 has been deployed on vehicle manufacturing assembly lines, working collaboratively with autonomous logistics vehicles and AMRs/AGVs through smart manufacturing management systems. Targets industrial manufacturing applications.
