Articulated manipulator

摘要

A miniaturized articulated manipulator 20 has a first arm member 31 A internally provided with two driving motors 33 and 34 , and a second arm member 30 B not provided with any devices corresponding to the driving motors 33 and 34 and capable of being miniaturized. The driving motors 33 and 34 can be disposed in common areas 135 at least partially overlapping each other with respect to a direction parallel to the axis of the first arm member 30 A and can be arranged in a direction perpendicular to the axis. Thus the first arm member 30 A can be formed in a small axial size. Thus the first arm 30 A and the second arm 30 B can be miniaturized and hence the articulated manipulator 20 can be formed in a short overall length.
