Last week I wrote about an underwater maintenance robot and how a lot of the near term opportunity in robotics is not about replacing humans wholesale, but about taking on jobs that are genuinely unsafe or simply ill suited for people. Here is another clean example of that.

CATL just announced that it has deployed humanoid robots on its battery production lines, using them for final battery pack testing. This is a stage where workers previously had to manually connect test plugs carrying hundreds of volts. Even small alignment errors can cause electrical arcing, visible sparks that create burn risk for workers and can quietly damage connectors in ways that hurt long term quality. The robot, called Moz, uses vision language action models to precisely align connectors and dynamically adjust insertion force, reducing spark risk while maintaining over 99 percent connection success. Because it can operate continuously and switch across battery models without fatigue, CATL says it can deliver up to three times the daily throughput of a human staffed station.
