Classification: CPC B  H  G | IPC B  G

Claim 1:
2. The actuator system according to claim 1, wherein
the movable member is a shaft that is movable in the axial direction, the shaft including a hollow part on a tip side,
the actuator is configured to pick up the workpiece by causing the shaft to move in the axial direction such that the tip of the shaft is moved to the predetermined position that is a position where the tip comes in contact with the workpiece, and by generating a negative pressure in the hollow part such that the workpiece is suctioned to the tip of the shaft, and
the external force detection sensor includes a load detection sensor and a suction detection sensor, the load detection sensor being provided at a transmission member that is a member configured to transmit power for moving the shaft in the axial direction to the shaft, and being configured to detect a load that is applied to the shaft, the suction detection sensor being attached to an air passage that is a passage through which air sucked out from the hollow part of the shaft flows when the negative pressure is applied to the hollow part, and being configured to detect that the workpiece is suctioned to the tip of the shaft.
