actuators are motors (electromechanical), and cylinders (pneumatic or hydraulic), although other types of actuators such as solenoids and pumps are also possible.\u00a0 How many actuators and what types are needed for a system depends on the application, available power sources, size and weight constraints, budget, and types of motion required.\u00a0 Motion can be linear or angular, continuous or discrete, and transmissions can be used to convert from one to the other.\u00a0 It is easiest to use as few actuators as necessary to reduce complexity, cost, and weight, although one actuator per degree of freedom is required.\u00a0 For similar reasons, it is also advisable to stick to one energy domain (either mechanical or fluid power).\u00a0 In senior design projects, pneumatics are preferred over hydraulics due to their lighter-duty applications and lower mess.\n\nActuators are selected based on effort and flow.\n<ul>\n \t<li>motor: effort = torque, flow = angular velocity<\/li>\n \t<li>cylinder: effort = force, flow = linear velocity or displacement<\/li>\n<\/ul>\nThese specs will be listed on manufacturers' websites in the product information pages.\u00a0 To determine the required effort and displacement for the actuator, calculations are required.\u00a0 These calculations should take into account the mass or inertia of the system, the resistance caused by friction and damping, and the effects of system position.\u00a0 The following materials explain how to calculate required motor torque and speed for an application.\n\n[embed]https:\/\/youtu.be\/59wQfvEBH9w[\/embed]\n\n<a href=\"https:\/\/libraryresources.nse.org.ng\/wp-content\/uploads\/sites\/4\/2026\/03\/Motor-Specing-Supplement.pdf\">Motor

(electromechanical), and cylinders (pneumatic or hydraulic), although other types of actuators such as solenoids and pumps are also possible.\u00a0 How many actuators and what types are needed for a system depends on the application, available power sources, size and weight constraints, budget, and types of motion required.\u00a0 Motion can be linear or angular, continuous or discrete, and transmissions can be used to convert from one to the other.\u00a0 It is easiest to use as few actuators as necessary to reduce complexity, cost, and weight, although one actuator per degree of freedom is required.\u00a0 For similar reasons, it is also advisable to stick to one energy domain (either mechanical or fluid power).\u00a0 In senior design projects, pneumatics are preferred over hydraulics due to their lighter-duty applications and lower mess.<\/p>\n<p>Actuators are selected based on effort and flow.<\/p>\n<ul>\n<li>motor: effort = torque, flow = angular velocity<\/li>\n<li>cylinder: effort = force, flow = linear velocity or displacement<\/li>\n<\/ul>\n<p>These specs will be listed on manufacturers&#8217; websites in the product information pages.\u00a0 To determine the required effort and displacement for the actuator, calculations are required.\u00a0 These calculations should take into account the mass or inertia of the system, the resistance caused by friction and damping, and the effects of system position.\u00a0 The following materials explain how to calculate required motor torque and speed for an application.<\/p>\n<p><iframe loading=\"lazy\" id=\"oembed-1\"
