Abstract: A robot system includes a first and second placing part where a workpiece is placed, and a transfer device disposed between the first and second placing part, the transfer device including a transfer-device interior space, a part of the periphery thereof being defined by a first wall provided to the first placing part side and a second wall provided to the second placing part side so as to oppose to the first wall, and a robot configured to transfer the workpiece between the first placing part and the second placing part. The first placing part is separated from the first wall by a first distance in a first direction connecting the first wall and the second wall. The second placing part is separated from the second wall by a second distance farther than the first distance in the first direction, and the robot is disposed closer to the second wall.

Abstract: A conveying hand includes a hand body having a flat plate shape, with an opposing surface opposing to a workpiece, a communicating port to be connected to a fluid path opening in the opposing surface, an annular seat surrounding the periphery of the communicating port on the opposing surface and having a suction opening communicating with the communicating port, and a film part covering the communicating port and deformable according to a pressure of a fluid inside the fluid path. The film part is flat in a state where the fluid path is not decompressed, and is disposed on an extended line of the opposing surface, or at the suction opening side from the opposing surface.
