Walker S2
Walker S2 is a full‑size bipedal humanoid robot designed for industrial and commercial environments. It features 52 degrees of freedom, high‑torque brushless motors, and dexterous five‑fingered hands. Powered by a dual‑battery hot‑swap system, it can autonomously exchange depleted packs at charging stations and resume tasks within minutes. Its AI stack combines vision‑based SLAM, real‑time path planning, and swarm coordination for reliable navigation and task sharing across multiple units. Walker S2 excels at material handling, assembly, inspection, and customer service roles in factories, warehouses, hotels, and retail spaces.
