create an electro-pneumatic system for the drilling process station .For the drilling process, a 15 kg workpiece was fed to the drill station. A workpiece will be pushed to the lower conveyor after drilling in order to be transferred to the inspection station before being raised to the upper conveyor for packaging. Each station should be depicted in your design, along with a flowchart and an entire electro-pneumatic circuit.
A pick and Place machine is being used to transfer a box. The arm is extended (out) by energizing a solenoid valve; when the valve is de-energizes, the arm retracts (in). In the same way, a second valve closes the grip (when energized) or opens the grip (when de-energized). Here's a diagram of this "machine": Grip Air Cylinder Grip open Grip Closed Box Arm Air Cylinder Arm In Arm Out The system is really slow... it actually takes 3-4 seconds for the arm to fully extend. An engineer created the below diagram. Start Pressed Time (seconds) Box Falls - 1 -2 -3 - 4 - 5 -6 –7 -8 – 9 – 10 Extend Arm Close Grip Question (finally!). Which statement is completely true regarding this design? It uses the Master Clock scheme. Given this diagram, the arm will probably start to retract before the grip fully closes. O If the arm takes 4 seconds to retract (return), the box will be dropped "mid-flight" It uses the Domino Scheme. Things can't happen in the wrong sequence. It uses the Master Clock…

a)If the system has a transfer function of the form G_P (s)=H(s)/(V_m (s) )=μ/(1+Ts) where µ is the gain and T is the time constant, calculate values for µ and T for the case where the valve is at position 3.
