I want to controll two dynamixel ax-12 servos using a arduino mega and I don`t know the commands that I should send to them using Serial.

Could anyone help me with this? (And please keep in mind that I don`t want any more hardware. Just arduino board)

  • I believe that that site might help you; support.robotis.com/en/techsupport_eng.htm#product/dynamixel/… On the left menu, seek that menu path: Home > Software Help > Software development kit > Controller Embedded C

With Dynamixel library you can use servo this easily:

#include <DynamixelSerial.h>

void setup(){
   Dynamixel.begin(1000000,2);  // Inicialize the servo at 1Mbps and Pin Control 2
}

void loop(){
    Dynamixel.move(1,0);
    delay(2000);
    Dynamixel.move(1,500);
    delay(2000);
    Dynamixel.move(1,1000);
    delay(2000);
}

Example moves servo and makes pauses of 2 sec.

Installation is easy:

Installation:

Copy the files from DynamixeSerial to your IDE libraries folder.

DynamixelSerial folder can be found here: https://sourceforge.net/projects/dynamixelforarduino/files/?source=navbar
