2014-07-03 15:39:28 -0500 | asked a question | "rostopic pub" does not work from out of eclipse. Hello, I write a little Java program. that communicates with the listener node from the beginner_tutorials package. It uses the rostopic pub command. When, after compiling, I call it manually via it works fine. A message "Hello!" with a random number appended is sent to the /chatter topic via rostopic pub. But when I run it directly out if Eclipse, it seems to run (no compile errors, Ready message at the end appears), but no message is sent to the chatter topic. What is wrong? It just want to run it directly from Eclipse without manually calling $ java rolex.Rolex |

2014-06-13 04:04:33 -0500 | asked a question | "roslaunch gazebo_ros willowgarage_world.launch" with dying gazebo-gui Hello, when I type from http://gazebosim.org/tutorials/?tut=r... the first time, everything works fine. But when I Ctrl+C the terminal or close the terminal and later type the command again, it says (The log file from the text does not exist). After that I have to restart my computer until it works again. How to solve the problem? I want to use the command without restarting everytime. Seems that the roslaunch processes from the first time are not finished cleanly. Maybe I need a method to finish all roslaunch started processes cleanly, when Ctrl+C does not work. |

2014-06-05 06:25:12 -0500 | commented answer | ROS Indigo: Where is rqt_plot OK, sorry. I'm new to ROS answers. I saw the PyQtGraph problem as a part of the rqt-plot issue. But now, I have googled it and so I found out, this is a separate issues independent from existing of rqt_plot in Indigo and solved it. |

2014-05-27 22:18:12 -0500 | answered a question | In a few days May will end. On which of the four remaining days will be ROS Indigo released? OK. When in June the release will be estimated? First week, second week? Can I install the development release of Indigo and use it tentatively? Does that make sense? And does "sudo apt-get update" automatically change Indigo to the final release, when it is online? |
