An automation and motion control system for theatrical objects, such as theatrical props, cameras, stunt persons, lighting, scenery, drapery or other similar types of devices or items, is provided to coordinate the movement of the objects on a large scale andor to control the operation of the objects. When a target acting position of the piston is inputted into a controller, the controller moves the piston to the target acting position so that a position measured by the length measurement sensor agrees with the target position by on-off controlling the solenoid valves. When the client determines that a failure may have occurred, the client may connect to a second data center to receive content from the content provider through the second data center. Liquid is sucked from the suction port 18 into the liquid chamber 9 by extension of the bellows 7, and the liquid in the liquid chamber 9 is discharged from the discharge port 19 by contraction of the bellows 7. The thus obtained -3a,6,6,9a-tetramethyl dodecahydronaphtho2,1-bfurans have a less off-odor and hardly suffer from deterioration of their smell during storage. A retransmission of the third signal from the remote further deactivates the transceiver from the \u201cready\u201d state to the \u201coff\u201d state.
