What are actuators?

 Actuators are devices that convert energy into physical motion or mechanical force, allowing them to perform a specific task or function. They are commonly used in various systems and machines, such as robotics, manufacturing, automotive, aerospace, and industrial equipment.

Actuators can be powered by various sources of energy, including electricity, hydraulic pressure, pneumatic pressure, or mechanical force. Some examples of common actuators include:

Electric actuators: These use electricity to produce motion, and they are commonly used in a variety of applications, such as robotics, automation, and control systems.

Hydraulic actuators: These use pressurized fluid, typically oil or water, to produce motion. They are commonly used in heavy machinery and construction equipment.

Pneumatic actuators: These use compressed air or gas to produce motion. They are commonly used in industrial automation and control systems.

Mechanical actuators: These use mechanical force, such as gears or levers, to produce motion. They are commonly used in simple machines and manual devices.


Actuators can be designed to perform various functions, such as rotating, linear motion, or gripping. They are essential components of many complex systems, and their design and operation vary depending on the specific application and requirements.
