I recently purchased the Mini Maestro 24-Channel USB Servo Controller https://www.pololu.com/catalog/product/1356 to control a few Hitech HS-7940TH http://www.servocity.com/html/hs-7940th_servo.html.
However, I don’t know how to set up the code to control the servo. Does anyone have any sample code to offer? I am running ubuntu 10.04 and ROS-Cturtle. Also, if the controller board is connected to my computer through miniusb, can the servos be power by that as well? Or, do I need an external power source?
