i want using arduino for control dc motor . What steps are needed ?? what change i need to use codes in ROS by Example Vol2 book . i want using arduino inestead arbotix controller to send command to DC motors. in book used arbotix package . like this example(please look at line 14) . i have to change this package??

If you don't want to change any code then this is not a ROS question I believe.

In general:

get a controller & amps that are compatible with your motors
find / write node with a similar enough ROS API as the dynamixel drivers
update the launch files

can i change this code and upload on arduino ??

I have no idea. I don't use dynamixels, nor any of the arbotix packages.

Here is an explanation of how you could have an arduino control your motors in a general way:

Components required:

An arduino with code that can control your motor
A computer running ROS and a node that publishes data to a topic, such as an integer that corresponds to a motor value that you would like to use as a throttle value for your motor

If you have those two things you can modify the arduino code by adding ROS functionality to it. Do the first of these 3 tutorials: http://wiki.ros.org/rosserial_arduino...

With these examples you will gain the knoweledge to allow you to send AND receive data to/from your arduino. With this knoweldge you can have your arduino serve a motor controller, by sending it throttle values and having it convert those throttle values to whatever signals are required to control your motors. Easy peazy lemon squeezy!

thanks . in book used arbotix package . like this example . i shoud to change this package??

You should create your own package and your own node to interface with the arduino. First get the arduino to control your motors, then create a package and node to talk to the arduino.

i want to run this example . what data is send to serial port ?? can i write program in arduino to get these data from serial port and manage dc motors?

Hello :)

ROBOTIS provides official opensource repository as ROBOTIS-GIT

In this repository, you can find Dynamixel-Workbench to control all series of DYNAMIXELS. Because it is official package for DYNAMIXEL, you can get a proper solution when you faced some problems.

Furthermore, they provides OpenManipulator package for manipulation. You can get a information when you use MoveIt! or Arduino with DYNAMIXELS.

This is WIKI page for DYNAMIXEL and introduced packages.

WIKI for DYNAMIXEL

WIKI for Dynamixel-Workbench

WIKI for OpenManipulator

Enjoy with it!
