Claims:1. Cost effective design of the pneumatic arm which is fabricated such that the solution is effective arm for pick and place.
2. Manual control is done by the pilot valves along with the automatic control using the microcontroller.
3. The movement of the arm is pneumatic with the usage of pneumatic cylinder for control of rotation using the mechanism of helical slot.
4. The actuator that works based on pneumatic power is the gripper for holding the cylindrical objects.
5. The pay load is maximum with a value of 50N and arm weight ranging 65N.
6. The work volume is semi hemisphere for picking the object and placing the object with the fabrication based on this concept.

, Description:Description of the system
• A valve for controlling the direction in 5/2 way with five ports and two positions of flow.
• Isolation and bypassing is done together by passing the fluid such as retracting or extending a double acting cylinder.
• Number of ways is there for the actuation of the valve conventional system uses the solenoid valves.
• Twisting of the lever of the solenoid valve is done manually for actuating the valve by an externally or internally pilot valve activated by the pneumatic system.
• The shaft is moved inside and outside using the pneumatic pilot valve or by the return of the spring going back to the initial position
• As the level of the pressure reduces the combined work of the valve and the actuator are considered for the operation.
• Usage of single solenoid returns the spring to its initial position from the other positional end of the system.
• The pressure inlet connection is done such that the connection is given to the double acting cylinder.
• Retraction of the piston is done using the piston extended to the normal position of the pneumatic system.
• Deenergising the solenoid to the initial position by blocking of the piston rod with the pressure released from the cylinder.
• Bouncing back of rod to its initial position using the return of the spring is condemned and exhausted in the solenoid.
• Pneumatic system has the energy which caused the system to transmit the potential energy stored in the tank of air receiver.
• The regulator of the pressure is used to control the pressure of the compressed air which is positioned using the receiver tank.
• The stored energy is positioned by the controlling circuit using the microcontroller.
• The regulator is positioned such that the air obtained from the receiver expands the valve for the downstream point of the system.
