Actuators
Actuators are how AI systems act on the physical world. Every joint, wheel, and gripper in a robot is driven by an actuator. Understanding torque, back-EMF, duty cycle, and control modes is what separates a builder from a hobbyist.
Servo Motor
A servo motor is a closed-loop actuator that holds a precise angular position. Used in robotic joints, grippers, steering mechanisms, and any system where position — not just speed — must be controlled.
DC Motor
A DC brushed motor converts electrical energy into continuous rotational motion. It is the most common actuator for wheeled robots, conveyor systems, and drivetrains — anywhere continuous rotation and variable speed are needed.
Stepper Motor
Precise open-loop position control for CNC and linear actuators

Solenoid
Linear electromagnetic actuator for latches and valves

Actuators → Action
In the AI action pipeline, a policy outputs commands that must be translated into actuator signals. Knowing the physical limits of your actuator — stall torque, PWM frequency, thermal envelope — prevents damage and enables safe, repeatable behaviours.
