In this case, maybe you could be interested in running ASEBA (http://mobots.epfl.ch/aseba.php) on the embedded system. ASEBA is a very small communication layer, originally developped to run on/communicate with micro-controllers. We have developped a ROS-ASEBA bridge that you could run on your control station to export all your system variables. http://www.ros.org/wiki/ethzasl_aseba HTH On Fri, May 6, 2011 at 10:15 AM, qiang yu wrote: > Thank you for your suggestion.
