Questions like this should be asked on http://answers.ros.org/ so that the answers are easy for other people to find. This sounds like a network problem; probably that the hostname of one of your machines doesn't resolve properly. Try setting ROS_HOSTNAME on both machines to the machine's IP address. For a longer-term solution, get your network/sysadmin to fix DNS or your computers so that your hostnames resolve properly. -Austin On Feb 8, 2012, at 12:22 AM, ELENA LAZKANO ORTEGA wrote: > > Hi again, > > the problem is that p2os communicates with roscore, but the p2os_dashboard does not communicate with the p2os node. The p2os node connencts to the H8S board and, hence it is not a serial/usb port permission issue. If we run everything on the robot (roscore, dashboard, p2os) adjusting the ROS_MASTER_URI to localhost, then it works. But we would like to execute everything but p2os node on a remote machine. > > Thanks again, > > elena > > Quoting karthik desingh : > >> Check if this helps >> http://answers.ros.org/question/3259/starting-p3dx-using-p2os >> Always better to post these questions in answers.ros.org >> >> On Tue, Feb 7, 2012 at 6:42 PM, ELENA LAZKANO ORTEGA wrote: >> >>> Hi, >>> >>> we are trying to use ros to make our pioneer robot move.
