HI, I want to make my robot move using Arduino (with hand made motor controller) and ROS Groovy. The problem is I have no idea to connect ROSARIA to Arduino for this. I have installed ROSARIA and I can toggle I/Os in arduino using ROSArduinoBridge. I planned to use kinect and build a map using it. Can anyone tell me how I should write a code for Arduino to support for ROSARIA? What is cmd_vel?
Hello, is your robot a Pioneer, ActivMedia, MobileRobots or Adept? If not, do not use rosaria which is dedicated to these robots. You can use a ros_arduino_bridge or rosserial. Rosserial is given with sample sketches to start easily: http://wiki.ros.org/rosserial_arduino/Tutorials
Hello, are you running rosaria on the Arduino? Or is it running on a computer, and you want to control it from the Arduino?
/RosAria/cmd_vel is a "topic" provided by the RosAria node. Messages published to this topic set velocities at which to request the robot to move. It's a way to send velocity commands to the robot. See the following for more details:

Thank you for the reply. ROSARIA is running on computer. But I don't have arduino sketch to connect to the ros node. I want to send command to Arduino using ROSARIA. But for that I need a sketch. I couldn't find it and have no idea about write about new one.
