German factories are beginning to test humanoid robots built with arms and legs as manufacturers explore their use on industrial work floors. A visit to sites where the first robot workers are operating shows that the machines still have a lot to learn. They are not yet ready to take over a factory's full range of duties, and their performance remains limited. Developers believe their skills could improve quickly as the technology develops. The report looks at what these machines can currently do in working environments. It also considers how greater use of humanoid robots could affect industrial employment. For workers, the central question is which tasks the robots will handle and how their roles may change.
