    • A robot system for use with a machine tool having a spindle, comprising a robot having a body for being mounted on the machine tool, an arm pivotally mounted on the body and rotatable in a plane transverse to an axial direction of the spindle of the machine tool, and a hand mounted on a distal end of said arm for gripping a workpiece for transfer to the machine tool, and a workpiece feeder disposed adjacent to the robot and movably supporting a succession of pallets for carrying unmachined and machined workpieces thereon. The workpiece feeder includes a first mechanism for moving the pallets along a path on the workpiece feeder and for positioning the pallets one at a time in a position in which an unmachined workpiece can be picked up from the pallet by the hand or a machined workpiece can be unloaded from the hand onto the pallet, and a second mechanism for moving the pallet toward the hand in the position for allowing the and to pick up the unmachined workpiece and to unload the machined workpiece, and for moving the pallet away from the hand.
