    摘要: An articulated industrial robot provided with a reference position setting means which includes two positioning contact parts 22 and 24, and the reference position setting means is provided for each joint 16 of a robot unit 10 in such a manner that the positioning contact parts 22 and 24 are brought into contact with each other so as to perform determination of a geometrical reference position for each joint drive source after the replacement of a defective drive motor or a defective reduction gear of the joint drive source. The determined geometrical reference position regarding each of the joint axes are stored in the robot controller to thereby achieve a single-axis mastering,and thus the reference position setting means simplifies single-axis mastering with respect to each joint axis of the robot unit without being subject to any spatial restrictions.

    摘要: A small-locus machining apparatus is attached to the distal end of a wrist of a robot but operable independently of a robot body. First and second drives of the apparatus are mounted on a base in such a manner that respective output spindles are parallel with each other. First and second rotational arms are coupled to the output spindles through decelerators, which are directly connected to the drives, allowing rotation in a plane orthogonal to the output spindles. These rotational arms and links interconnecting the rotational arms constitute a link mechanism having, for example, five joints. A tool is attached to this link mechanism, and the rotational amounts of the first and second arms are detected to determine the coordinate position of the tool.
