Actuators are devices which are mechanical or electro-
mechanical in nature and provide limited or controlled
movements which can be operated electrically, manually
or by fluids such as hydraulic, air etc. Based on the type
of motion produced by actuators they can be broadly
classified into two categories namely linear actuators
and rotary actuators.
