A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...
Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...
This is commonly done using the Servo library in Arduino. To sweep a servo with an Arduino, connect the servo's VCC (red wire) to 5V, GND (black/brown) to GND, and signal (yellow/white) to a PWM-capable pin (e.g., Pin 9). Use the Servo library to control movement. The code below gradually moves the servo from 0° to 180° and back in a loop.
The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
In a properly configured control system, the servo motor rotates at a velocity that very closely approximates the velocity signal being received by the servo drive from the control system. Several parameters, such as stiffness (also known as proportional gain), damping (also known as derivative gain), and feedback gain, can be adjusted to ...
