Hi,

we are trying to use ros to make our pioneer robot move. We followed the steps in http://www.ros.org/wiki/p2os/Tutorials/Getting%20Started%20with%20p2os
and configured the ROS_MASTER_URI and ROS_MASTER_IP of the base computer and the pioneer onboard PC accordingly.

We run roscore on the base computer and the p2os_driver on the robot. The robot communicates with the H8S board properly. But when we run p2os_dashboard on the base computer, neither the battery level nor the option to enable/disable the motors change. Moreover, no message arrives to the dashboard although we do not see any error message on the terminal.

Any hint?

thanks in advance,

elena
