An articulated manipulator includes a base body, a first arm body, a second arm body having a second arm center axis, and a third arm body. A first joint part connects the base body and a first end portion of the first arm body rotatably around a first rotation axis. A second joint part connects a second end portion of the first arm body and a third end portion of the second arm body rotatably around a second rotation axis. A third joint part connects a fourth end portion of the second arm body and a fifth end portion of the third arm body rotatably around the third rotation axis. When the first, second and third arm bodies are all erected with respect to a installation surface, the first rotation axis, the second arm center axis, and the third rotation axis are substantially aligned with each other.

This invention provides a manipulator that can facilitate a teaching method, improve the operation speed of an arm, and mount a heavy load in a narrow space. The manipulator includes a plurality of arm bodies provided in series, joint parts rotatably connecting two adjacent arm bodies, and the joint parts in which slope of rotation axes of the adjacent joints are 90 degrees, at least one linear body disposed in the joint parts coaxially with the rotation axes. The joint parts are composed of a servo motor, and a speed-reduction mechanism. The rotation axes of the servo motor, the speed-reduction mechanism and the joint parts become the same axis.
