Servo Motor

Servo Motor What are Servo Motors?
Servo refers to an error sensing feedback control which is used to correct the performance of a system. Servo or RC Servo Motors are DC motors equipped with a servo mechanism for precise control of angular position. The RC servo motors usually have a rotation limit from 90° to 180°. Some servos also have rotation limit of 360° or more. But servos do not rotate continually. Their rotation is restricted in between the fixed angles.
 
Where are Servos used?
The Servos are used for precision positioning. They are used in robotic arms and legs, sensor scanners and in RC toys like RC helicopter, airplanes and cars.

Servo Motor manufacturers
There are four major manufacturers of servo motors: Futaba, Hitec, Airtronics and JR radios. Futaba and Hitec servos have nowadays dominated the market. Their servos are same except some interfacing differences like the wire colors, connector type, spline etc.

hi sir

this was really informative.I m using HS-311 servo mortors with ATMEGA 16 microcontroller.for making it rotate to 0degree i gave 0.33 us on pulse and 20 ms off pulse,for 90 degree i gave 0.95ms on pulse and for 180 degree......1.56 ms pulse.... it worked effectively.for2 servos i had to use 2 avr ports. i want to use 4 servos in only 1 port in ATMEGA 16,how can it be done without interfering with other servo's PWM??

Hi sir

Im using MG995 twoerPro servo motor interfacing with arduino.
im not getting result as programed 
I connected red to +5v
brown to ground

& yellow for signal to arduinos pin 9

 

and want to rotate 20 degrees like this

for (i=0;i<=180; i=i+20)

move 20 degree

 

 

here is the complete program

Submitted by ronak2010 on Wed, 16/05/2012 - 08:19.

here is the complete program (i tested with arduino uno board with vs2 and v0006 servo)

 

 

#include <Servo.h> 
 
Servo myservo;  // create servo object to control a servo 
               
 
int pos = 0;    // variable to store the servo position 
 
void setup() 
{ 
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object 
} 
 
 
void loop() 
{ 
  for(pos = 0; pos < 180; pos += 20)  // goes from 0 degrees to 180 degrees 
  {                                  // in steps of 20 degree 
    myservo.write(pos);              // tell servo to go to position in variable 'pos' 
    delay(15);                       // waits 15ms for the servo to reach the position 
  } 
  for(pos = 180; pos>=1; pos-=20)     // goes from 180 degrees to 0 degrees 
  {                                
    myservo.write(pos);              // tell servo to go to position in variable 'pos' 
    delay(15);                       // waits 15ms for the servo to reach the position
