Product overview
About UBTech Walker S1
The Walker S1 is a full-size bipedal humanoid built by UBTech Robotics for industrial work. UBTech says its design combines a large language model for general task planning with semantic VSLAM navigation and a learning-based whole-body motion controller, aimed at the generalization needs of industrial scenarios (s1).
UBTech's product page states that the Walker S1 has been introduced into vehicle manufacturing assembly lines and that it works with autonomous logistics vehicles and AMRs/AGVs through a smart manufacturing management system (s1). A 2025 peer-reviewed review lists the robot at 172 cm, 76 kg and 41 degrees of freedom (s4). Heise reports that UBTech is said to have received around 500 orders for the Walker S1 in 2024 from automotive companies (s2).
The product page gives no price, launch date or order option. Its specifications appear only as an image, and it asks visitors to reach out or become a partner (s1). UBTech's contact section lists inquiry addresses by scenario, including cooperate@ubtrobot.com for industrial scenarios (s5).
“Walker S1 has been introduced into vehicle manufacturing assembly lines to assist in car production.”
