Inference on results obtained by experimenting to control speed and precise extension of a pneumatic cylinder in a cost-effective manner

The paper investigates the viability and cost effectiveness of a stepper/servo motors to operate a ball valve in sync with an infrared/laser displacement sensor to obtain precise location of the air piston under varying and static load. The experiment conducted in reference making a viable Exo-Skelton it was found out that pneumatic system had an edge over hydraulics due to its lightweight design, speed, and its being operational even after loss of pressure. But the key area of hindrance remained the cost and effectiveness of pneumatic cylinder present in the market with precise displacement control owing to dynamically variable loads applicable on the cylinder. A custom valve (ball valve/pin valve) was built, controlled with servo motors and a displacement sensor to track the exact position of the piston rod, With respect to the linear motion of its piston rod. The system is divided into two parts firstly being the servo operated ball valves which h are formed by mounting a servo on the operating handle of the ball valve, and a displacement sensor tracking the movement of piston rod
