An actuator is essentially a device that gets things moving or working. Picture it like this: it's the muscle of a system, taking in energy and using it to create physical movement. There are three main types: - Pneumatic actuators: These ones work using compressed air. - Hydraulic actuators: They use different liquids to generate movement. - Electric actuators: These use electricity to do their job. So, whether it's pushing, pulling, or twisting, actuators are the ones making it happen! 🚀 #Eng
