Most robotic industries depend on using (servo motors) and (stepper motors) orcontinuous current motors (DC motors) for movement transition, which increases the cost and complicates the robot’s controlling process, as well as its driving circuits. This essay deals with using pneumatic in the new design and building of a robot’s arm, that can manage to do many tasks with a much lower budget than the one needed for any of the above mentioned methods, that’s because it can be used for tasks that need high speed and capacity, but don’t need precision.
