What are the functions of robotic actuators?

Robotic actuators are critical components that facilitate movement within robotic systems. Their primary function is to convert different forms of energy—such as electrical, hydraulic, or pneumatic energy—into mechanical motion. This conversion is essential because it allows the robot to perform tasks by moving its joints or elements, thus executing pre-programmed commands or maneuvers.

The importance of actuators cannot be overstated; they are essentially the 'muscles' of the robot, providing the necessary force to create motion and allow robots to interact with their environment effectively. This might include tasks like picking up objects, moving arms or legs, or rotating parts to perform complex actions.

In contrast, controlling power supplies, storing data from sensors, and facilitating communication between robots are functions associated with other components in the robotic system. These functions support the overall operation and coordination of the robot but do not relate directly to the primary function of motion that actuators provide.
