2014-03-10 05:29:53 -0500 | asked a question | How does ros execute my nodes on a remote machine? When specifying the machine-tag for a ros-node in a launch-file one is principally able to run a ros-node on any reachable machine in the network that is configured for ros. Do I get this right? If yes, I am wondering about the following questions:
(the wiki told me to include this: http://wiki.ros.org/ROS/Tutorials/Mul... ) |

2013-11-22 04:31:42 -0500 | asked a question | Is it possible to connect machines with different ros versions? I am running a robot pc (NUC) with ros-fuerte and my laptop with ros-hydro. I want to run the main nodes on the robot and the debugging nodes like rqt_plot and some hand made GUIs that use services on my laptop. Following the instructions from the ros wiki on NetworkSetup and MultipleMachines everything gets started and I can see all services and topic doing rostopic/rosservice list on both machines. But if I start my debugging nodes on the laptop (the robot fuerte is running the roscore) the topics and services from the robot seem not reachable. It just doesn't work, I mean there is no output saying connection failed or anything. Only if I try rosservice info <my_service> it says: Node: /motor_control URI: rosrpc://NUC:47241 ERROR: Unable to communicate with service [/motor_control/SpeedLeftGainControl], address [rosrpc://NUC:47241] Can this be due to discompabilities between fuerte and hydro? I have no other idea, since everything else works like described. |
