Abstract
A manipulator includes a first arm having a first reduction gear unit built therein, a second arm fitted through the first arm and having a second reduction gear unit built therein, and a third arm fitted through the second arm and having a third reduction gear unit built therein. To avoid any possible interference between, for example, a welding torch, and a portion of the manipulator during operation of the manipulator, the drive axis of the third reduction gear unit is spaced apart a distance from a drive axis of the second reduction gear unit.
