Overview
RobotShop's name for UBTECH's Walker Tienkung (Tiangong Walker), a 172 cm research and education humanoid co-developed with the Beijing Humanoid Robot Innovation Center on its Tiangong platform and launched in March 2025. Unlike the enterprise-only Walker S2, it is sold openly to universities and labs, with open interfaces for every joint and sensor, URDF models and reinforcement-learning training tools. The Voice & Vision version has 21 DOF with simple 4-DOF arms, while the Embodied Intelligence version adds 7-DOF arms, dexterous hands, force sensors and a second Jetson AGX Orin.
