<div id="readability-page-1"><div> The world’s leading battery producer, CATL, has decided to flex some of its robot muscles this month. It has revealed the first humanoid robot battery production line…. That is, a battery production line “manned” by humanoid robots. First of all, yes, these humanoid robots have apparently replaced human workers. In fact, one robot’s daily workload is reportedly triple that of a human worker…. These humanoid robots are being deployed at CATL’s battery factory in Luoyang, Henan. “CATL (HKG: 3750, SHE: 300750) has become the world’s first battery manufacturer to deploy humanoid robots at scale in battery pack production, replacing human labor in several critical processes,” CnEVPost writes. “Named ‘Xiaomo’ (or Little Mo), the humanoid robot can now precisely execute complex tasks like battery connector insertion, marking a milestone breakthrough in applying embodied intelligence to manufacturing, the company said.” (Note that another Chinese site, CarNewsChina, translates the robot name as “Moz.”) <img height="900" src="https://imageproxy.pbkrs.com/https://cleantechnica.com/wp-content/uploads/2025/12/CATL-humanoid-robot-battery-production.jpeg?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="1600" original-src="https://imageproxy.pbkrs.com/https://cleantechnica.com/wp-content/uploads/2025/12/CATL-humanoid-robot-battery-production.jpeg"/> Hmm…. Perhaps the era of robots replacing human workers really is upon us. How many more things will robots be doing in factories in 2026? And then there are all the coming robotaxis. What about autonomously driven long-distance trucks, warehouse robots, and robot waiters (well, not yet I’m sure). “Xiaomo replaces human operators in the EOL (End of Line) and DCR (Direct Current Internal Resistance) processes during battery pack production — the final functional tests before the packs leave the line,” CnEVPost goes on. “These stages traditionally relied on manual labor, where workers had to precisely connect test plugs carrying hundreds of volts of high voltage to designated positions on the battery pack. This process carried risks of high-voltage arcing and presented challenges including inconsistent efficiency and quality. Xiaomo has transformed this situation, as it incorporates an end-to-end Vision-Language-Action (VLA) model, granting it robust environmental perception and task execution capabilities, CATL said. “The humanoid robot autonomously handles uncertainties like material position deviations and connection point variations, dynamically adjusting its operational posture in real time. When inserting or removing flexible wiring harnesses, it dynamically modulates force to ensure reliable connections without damaging components.” CarNewsChina adds: “According to CATL, the robot excels in three key areas: <ul> <li>Precision adaptation: Moz can independently adjust to incoming material position deviations and connection point changes, continuously modifying its operational posture in real-time.</li> <li>Flexible operation: When inserting and removing flexible wire harnesses, Moz dynamically adjusts its force to ensure reliable connections without damaging components.</li> <li>Efficiency and reliability: In actual production, Moz maintains a connection success rate above 99%, with operational efficiency matching that of skilled human workers.”</li> </ul> The robot was not developed by CATL, but rather by Spirit AI, a startup based in Hangzhou and just founded in 2024! That said, CATL is a financial backer of the startup. So, we may as well say it’s underneath the CATL umbrella. Naturally, the robot — whether you call it Little Mo or Moz — is powered by CATL batteries. </div></div>
