6.1. Overview#

An actuator creates physical action such as rotation, linear motion, heat, sound, light or fluid flow.

6.1.1. Types of Actuators#

In this lesson we will learn more about the following actuator types:

  • Rotary Actuators: produce rotational movement (e.g. motors)

  • Linear Actuators : produce straight-line movement (e.g. solenoids)

We will also explore the different systems used to perform work that power these actuators:

  • Electric Systems

  • Hydraulic Systems

  • Pneumatic Systems

6.1.2. Motion#

Actuators can only move in the ways that their mechanical design allows. We will learn how to describe and plan motion using:

  • Constraints

  • Degrees of Freedom (DOF)

  • Inverse Kinematics

6.1.3. Communication and Control#

Finally, we will learn how microcontrollers send instructions to actuators.
