As you may see, the scheme is completely pneumatic, having only mechanical switches which are toggled only by the mechanical movement of the robotic arm. This scheme corresponds to three consecutive movements of 2 DOF arm with a gripper. The robotic arm movement simulation itself you may see in the info card (right corner pop-up message).
