ARTICULATED ROBOT.

摘要

An articulated robot having a rhomboidal link mechanism consisting of a fixed base (1) provided with a horizontal upper surface, a first arm (2) supported so that it can be turned around a pivot perpendicular to the upper surface of the fixed base (1), a first auxiliary link (3) parallel to the first arm (2), and a second auxiliary link (4) by which the end portions, which are away from the fixed base, of the first arm (2) and first auxiliary link (3) are coupled so that these end portions can be pivotally moved; and a second arm (5) provided so that it can be turned on the second auxiliary link (4) and around a pivot extending in parallel with that perpendicular to the upper surface of the fixed base (1). The present invention can thus provide an articulated robot capable of moving at a high speed between two distant points without the motion of the second arm (5) limited by the first arm (2).
