Airbus Pilot Launch
UBTECH Robotics unveils the Walker S2 humanoid in a groundbreaking trial with Airbus, where the robot demonstrates its pioneering autonomous battery swapping during aircraft assembly simulations. This collaboration tests the machine's ability to perform uninterrupted maintenance tasks, swapping depleted batteries in under three minutes to sustain 24/7 operations on factory floors. Industry watchers see this as a pivotal step toward embedding humanoids in high-stakes aerospace environments, potentially slashing downtime in precision manufacturing by integrating seamless power management with dexterous handling.
Swap Innovation Spotlight
Walker S2 revolutionizes uptime through its dual-battery system, where dexterous arms coordinate to extract, dock, and install fresh packs without human intervention. This hot-swap mechanism, paired with real-time monitoring, lets the robot toggle between single- or dual-battery modes based on task demands, ensuring relentless productivity. In Airbus scenarios, it navigates tight assembly spaces, prioritizing critical jobs like part insertion over recharging, transforming battery logistics from a bottleneck into a background process.

Balance Tech Leap
Engineers at UBTECH engineered Walker S2 with whole-body dynamic balancing, enabling deep squats to 125 degrees and waist rotations up to 162 degrees while hefting 15kg loads. Fourth-generation bionic arms and hands deliver sub-millimeter precision, fused with dual RGB stereo vision for human-like depth perception. These advances allow fluid adaptation to aircraft assembly's erratic perturbations, like uneven floors or sudden shifts, making the robot a reliable partner in dynamic human-robot teams.
Assembly Role Expansion
Beyond batteries, Walker S2 tackles Airbus-inspired workflows such as picking parts for fuselage assembly, quality checks on rivets, and material shuttling across production lines. Its bipedal gait navigates cluttered hangars, while AI-driven Co-Agent planning handles exceptions like misaligned components. Early trials hint at 30% faster cycle times for repetitive tasks, freeing skilled workers for complex decisions and positioning humanoids as indispensable co-workers in aviation's push for efficiency.

Dexterity Skill Fusion
Walker S2's binocular RGB cameras and LiDAR enable nuanced spatial awareness for collaborative interactions, like handing tools to technicians mid-assembly. Forty-two active degrees of freedom across 52 joints drive natural bipedal strides at 7.2 km/h, with foot IMUs and force sensors ensuring stable partnerships in crowded spaces. Tactile fingertips and arm torque sensing empower gentle manipulations of delicate aircraft panels, while the Linux RTOS and BrainNet 2.0 orchestrate prolonged human-centric sessions without fatigue.
