Abstract: A robot system includes a first conveyor conveying a workpiece to a first position in a conveying direction along a transport line, a second conveyor conveying the workpiece from a second position along a first line perpendicular to the transport line, and a robot conveying the workpiece from the first to second positions. The robot includes a base fixed to a fixed position apart from the first line in the conveying direction, and an arm base movably connected to the base. A first arm is connected to the arm base rotatably about a first axis perpendicular to the transport and first lines. A second arm is connected to the first arm rotatably about a second axis parallel to the first axis. An arm tip is connected to the second arm rotatably about a third axis parallel to the first axis. A workpiece holder is provided below the arm tip.
