Abstract
A robot includes an angular velocity sensor installed to a second horizontal arm and for obtaining the angular velocity of the first horizontal arm with respect to a base, and suppresses the vibration of the first horizontal arm by driving a first electric motor based on the angular velocity of the first horizontal arm. In the robot, an electric wire to be connected to a second electric motor incorporated in the second horizontal arm and electric wire to be connected to the angular velocity sensor are laid around through a wiring duct having end portions coupled respectively to the base and the second horizontal arm, disposed outside the first horizontal arm and outside the second horizontal arm, and having a passage leading to the inside of the base and the inside of the second horizontal arm.

12. A horizontal articulated robot comprising:
-
a first arm coupled to a base; a second arm that comprises a body and a cover, and the body is coupled to the base via at least the first arm; an angular velocity sensor positioned at the second arm under the cover, wherein a first surface of the angular velocity sensor is coupled to a first surface of the body of the second arm; a connection section positioned along an outer surface of the cover of the second arm, wherein the angular velocity sensor is positioned between the first surface of the body and the connection section; a piping member having one end coupled to the base and the other end coupled to the second arm via the connection section; a wire extending through the piping member, the connection section, and the second arm, wherein the wire is coupled to the angular velocity sensor along a second surface of the angular velocity sensor that is different from the first surface of the angular velocity sensor; a belt disposed inside the second arm; and a plurality of supporting legs extending parallel to each other and located within the second arm, wherein the angular velocity sensor is coupled to the body of the base by way of the supporting legs and the angular velocity sensor is positioned above the belt by way of the supporting legs. - View Dependent Claims (13, 14, 15)
