7. Actuators and Their Role in Automation
Actuators are essential components in robotics and automation systems, responsible for converting control signals into mechanical motion. Their classification is based on energy sources such as electrical, hydraulic, and pneumatic systems, and they vary in application from industrial automation to civil engineering. The selection of actuators involves considering factors like required motion, load, speed, and environmental conditions, with emerging technologies paving the way for more advanced actuation methods.
