Design a finite state machine to control a device which consists of five sensors lined up in a row, controlled by the finite state machine’s outputs Zero, One, Two, Three, and Four. The five sensors scan an area outside a building. Each sensor scans one part of that area. When the sensor’s output is one, it is scanning its area, and when the sensor’s output is zero, it is not scanning its area. Only one sensor is on at a time meaning that each sensor takes a turn at being the sensor that is currently on. This turn taking follows a backand-forth motion going from left to right and then going from right to left. It is this “motion” that the finite state machine controls. The clock speed (which you do not need to know) regulates the rate of the motion. There are no inputs for the finite state machine.

- A PLC is used to control a single-axis robot, in which the axis is driven by a pneumatic cylinder. An output signal to the pneumatic cylinder causes it to extend (ON state). When there is no signal, the pneumatic cylinder retracts (OFF state). The gripper is an also driven by a pneumatic cylinder. The gripper open position is an OFF state and the closed position is an ON state. In order to perform a task, the following sequence of operations must be performed: TH Sequence No. Аxis Gripper OFF OFF 1 ON OFF ON ON 3 OFF ON 4 OFF OFF The process begins when the start bush button is ON and a part triggers a limit switch. For safety, an emergency switch is used to shut off the entire system.
