Robotics Motors in Robotics
DC motors spin continuously in one direction at a speed determined by voltage. They're cheap, powerful, and fast — ideal for wheels and propellers. Drawback: no position feedback.
Servo motors hold a specific angle (0–180°). They're precise and slow, perfect for robotic arms, camera pan-tilt, or gripper control. Built-in feedback allows position control.
Stepper motors move in discrete steps (e.g., 200 steps per revolution). Each electrical pulse moves one step. They're precise but slow — common in 3D printers and CNC machines.
Robotics Motors — Syntax
// DC Motor: Speed control (PWM)
analogWrite(motorPin, 200); // Faster
// Servo: Angle control
servo.write(90); // Hold 90 degrees
// Stepper: Step control (pseudocode)
for (i = 0; i < 200; i++) {
