ABSTRACT:
A two-arm transfer robot includes a swivel base arranged to swivel about a vertical swivel axis, and a pair of link arm mechanisms attached to the swivel base. These two link arm mechanisms are symmetrical in structure and function with respect to the swivel axis. A first hand member is supported by one of the link arm mechanisms for carrying a work, while a second hand member is supported by the other link arm mechanism for carrying a work. The first hand member and the second hand member are horizontally movable at the same height without interfering with each other.
