3. (a) Define actuator. Difference between hydraulic and pneumatic actuator.
(b) Explain the working principle of pneumatic power system with neat sketch.
(c) A single link robot with a rotary joint is motionless at θ = 15 degrees. It is desired to move the joint in a smooth manner to θ = 75 degrees in 3 seconds. Find the coefficients of a cubic which accomplishes this motion and brings the manipulator to rest at the goal. Find the position of the joint as a function of time.
