This invention relates to a three degree-of-freedom and a horizontal multi-joint industrial robot and in particular to a method of saving space for installing the robot.
The horizontal multi-joint industrial robot has three arms comprising first, second and third arm sections which are sequentially attached from a base member. A robot hand is connected to the distal end portion of the third arm section.
When the robot hand moves in a forward direction, rotational movement of the arms is controlled so as to select one of the folding directions such that an angle between a robot hand direction and the third arm section becomes at least 90°. This enables the distal end portion of the second arm section to always position behind a distal end portion of the third arm section with respect to the robot hand forward direction, making it possible to decrease the robot arm movable area that makes no contribution toward conveying a workpiece.
