UBTech’s humanoid robot hits tennis shots in a controlled rally test

Chinese robotics company UBTech has demonstrated its Walker S2 humanoid robot performing a controlled tennis rally against a human, showcasing advanced capabilities beyond scripted demos. The robot successfully hits moving tennis balls with speed, precision, and confidence, managing complex tasks such as perception, prediction, balance, and rapid motion in real-time. This demonstration highlights the robot’s ability to absorb impact shocks and maintain stability during dynamic interactions, a significant challenge for humanoid robots. Walker S2’s whole-body dynamic balance system enables it to perform deep squats, forward pitching up to 125 degrees, and lift payloads up to 33 pounds within a 1.8-meter range, supporting physically demanding tasks. Walker S2 is equipped with a self-developed binocular stereo vision system using RGB cameras and deep learning for real-time depth mapping, enabling accurate spatial awareness and object recognition. Its coordination relies on UBTech’s Co-Agent system within the BrainNet 2.0 AI architecture, which integrates task-driven decision-making with real-time
