What is the role of an actuator in a robotic system?

The role of an actuator in a robotic system is to convert energy into motion. Actuators are essential components that facilitate movement by taking a form of energy, such as electrical, hydraulic, or pneumatic energy, and converting it into mechanical movement. This enables the robot to perform a wide range of tasks, such as moving arms, legs, tools, or other parts of the robotic system.

Actuators are vital for translating the commands or signals received from the control system into physical actions, thereby bringing the robot's programmed instructions to life. The effectiveness of an actuator directly impacts the robot's ability to interact with its environment, delivering precise and controlled movements that are critical for tasks ranging from industrial automation to robotic surgery.
