2014-08-21 15:10:56 -0500 | commented answer | rqt_plot issues in indigo It is entirely possible that the first issue was caused by not having the workspace sourced properly, because the problem is gone - but I can make it appear by skipping the sourcing step. The second issue I can live with for now until the next update. Interestingly enough an array works fine if it's defined as fixed size, so my custom message with a 6 element array works, but not JointState. Thanks! |
2014-08-20 04:08:04 -0500 | asked a question | rqt_plot issues in indigo I have a ros node which publishes a custom message as well as sensor_msgs/JointState messages. Both show up correctly in rostopic echo but not in rqt_plot. When starting up rqt_plot I see an error: could not get message class for topic type "MyCustomMsg" on topic "my_topic". The message does not show up in rqt_plot's dropdown menu, and can't be added if I type it in explicitly. The message is a float64[] array and should be accessible as my_topic/my_message_data[0] but this doesn't work. The problem is similar to this thread: http://answers.ros.org/question/72739... except that restarting doesn't solve it. The second problem is with the JointState message and similar to https://github.com/ros-visualization/... so the question is if this is fixed in the next indigo release? |

2014-08-16 00:52:35 -0500 | answered a question | c++11 library for indigo catkin package I'm getting weird linker errors when testing to build a simple catkin package with this library and c++11 enabled in the compiler. So it won't work then. Thanks for the responses. |
2014-08-15 04:07:35 -0500 | asked a question | c++11 library for indigo catkin package Hi, I have a library (a server using std::thread and some other c++11 things like auto) which is compiled into mylib.a. I want to use this library in my indigo catkin ros node. But apparently ROS is c++03 only for now. Do I have to rewrite the library to c++03? Or can I use it as long as the ros node itself stays c++03 compatible? |

2014-07-01 01:42:14 -0500 | commented question | ubuntu 12.04 VM installation sever down? Still can't download the linked Ubuntu image. I downloaded a 12.04 image from http:/ /www.tren dsigma.net/vm ware/ubun tu1204.html# (remove spaces) and installed Fuerte on it. Seems ok. |

2014-06-30 01:27:19 -0500 | asked a question | ubuntu 12.04 VM installation sever down? I have been trying to download the Ubuntu 12.04 Virtual Machine with Hydro Medusa pre-installed for several days now, and I get either of these errors: server isn't responding, server bandwidth exceeded. The download link takes me to (can't post links yet so I put some spaces in the url) http:/ /no otrix.com/do wnloads/#Ro sVM , then I get the errors. Tried downloading in two completely separate locations (at least one of these is guaranteed to have no interfering proxy). Is the server down, if so, is there a mirror somewhere? Or, is there another good place to get a clean Ubuntu 12.04 VM image that I can install on? Edit: (Found one, see comment). |

2014-06-28 14:15:41 -0500 | commented answer | MoveIt arm_navigation_msgs compatible, how to port? Thanks for that info! There is a URDF file included which hopefully works. Looks like I will test it first on Fuerte and later rewrite it completely for MoveIt in Hydro. |

2014-06-27 05:31:08 -0500 | asked a question | MoveIt arm_navigation_msgs compatible, how to port? I'm new to ROS so this is perhaps a newbie question, sorry about that. I'm trying to connect our kuka 850 to ROS, and came across a third party stack on git (cant post link yet, here is with spaces inserted) https://github.com/uobirlab/kuka . The manifest lists arm_navigation_msgs as a dependency, but wiki says this is deprecated and to use MoveIt instead. My options are then to try and build the stack as is, or port it to MoveIt.
