Description
Walker S2 is UBTECH’s full‑size industrial humanoid designed for factory work rather than demos. It combines high‑stability bipedal locomotion with a software stack aimed at autonomous task planning and recovery. The headline capability is a self‑battery‑swap system that removes most energy downtime, allowing near‑continuous operation in shift‑based environments.
Mechanically, the platform targets human‑scale reach and strength. A 52‑DOF body, high‑torque waist, and fourth‑generation dexterous hands enable manipulation across a roughly two‑meter workspace with up to 15 kilograms of load. The hands are described as sub‑millimeter‑precision and durability‑tested, reflecting the move from lab prototypes toward ruggedized industrial hardware.
On the perception and autonomy side, Walker S2 uses dual‑RGB stereo vision in the head for human‑like depth perception, then fuses this with UBTECH’s BrainNet 2.0 and Co‑Agent stack for multimodal reasoning, skill execution, and exception handling. In demos, the robot performs natural bipedal walking, dynamic balancing, object handling, and the coordinated actions required to remove, dock, and reinstall battery modules without human assistance.
Practically, the system is aimed at automotive and general manufacturing where uptime, repeatability, and safe human–robot coexistence are critical. While some specifications remain undisclosed and press reports differ on size and mass, the direction is clear: Walker S2 pushes humanoids toward round‑the‑clock, production‑floor utility, with manipulation and autonomy designed for real factories rather than just stages.
