ABSTRACT:
A two-armed transfer robot includes a first arm mechanism and a second arm mechanism. Each arm mechanism has a handling member for carrying a workpiece. The robot further includes a stationary base member and four shafts rotatable about a common vertical axis. Driving devices for the respective shafts are attached to the base frame. The first and second arm mechanisms are actuated upon rotation of the shafts driven by the driving devices. When the shafts are rotated in a same direction, the handling members of the arm mechanisms are caused to pivot about the common vertical axis. When the shafts are rotated in opposite directions, the handling members are caused to linearly move toward or away from the axis. The two arm mechanisms are vertically spaced from each other, so that they do not interfere with each other.
