<p>Provided is an industrial robot wherein although it is possible to extend and retract two arms separately, it is possible to stabilize the extension and retraction movements of the two arms, as well as the rotational movements thereof with respect to the main body section. A first arm (5) is provided with a first arm section (11) and with a second arm section (12) which is held by the first arm section (11). A second arm (6) is provided with a third arm section (13) and with a fourth arm section (14) which is held by the third arm section (13). In the robot (1), it is possible to separately extend and retract the first arm (5) and the second arm (6). Furthermore, the robot (1) is configured in such a way that the rotational movement center of the first arm section (11) and the rotational movement center of the third arm section (13) are disposed on the same axis, and that the first arm (5) and the second arm (6) are approximately symmetric with respect to a phantom line (L) when the first arm (5) and the second arm (6) are in the retracted state. The first arm section (11), the third arm section (13), the second arm section (12), and the fourth arm section (14) are disposed in this order in the vertical direction.</p> |
