| 20080213077 | Articulated robot - An articulated robot includes a first arm which is horizontally angularly movable, a sectorial support plate coaxial with a center about which the first arm is angularly movable, an auxiliary arm parallel to the first arm, and a joint member connected to respective distal ends of the first arm and the auxiliary arm. An arcuate rail is mounted on the support plate. The first arm, the auxiliary arm, and the joint member make up a parallel link mechanism. The arcuate rail engages an engaging assembly mounted on an upper surface of the first arm. A second arm is angularly movably connected to the joint member, and a third arm is angularly movably connected to the distal end of the second arm. An end effector for attracting a workpiece is connected to the distal end of the third arm. | 09-04-2008 |
