2013-10-02 11:26:25 -0500 | commented question | ROS groovy update screwed up workspace setup in some cases? I'm seeing this problem too. Since ROS_ROOT has changed from the correct value of `/opt/ros/groovy/share/ros` to `/share/ros`, all tab-completion fails because they rely on rosbash (which needs ROS_ROOT set properly). As a *very* temporary fix, you can `export ROS_ROOT=/opt/ros/groovy/share/ros` and it appears to fix the problem. On systems sourcing a Catkin workspace, this problem can be fixed by running catkin_make in the workspace. This will set ROS_ROOT correctly. |

2013-07-12 20:32:54 -0500 | commented answer | Qtcreator with Catkin I believe I've tried that, and it doesn't work. Qtcreator ends up making a miniature copy of the devel/ directory structure inside build/package_name directory. |
2013-07-12 20:29:16 -0500 | commented answer | Qtcreator with Catkin That solves the problem. It's not the prettiest solution to put all the packages in one Qtcreator project, but I guess it fits the usage model of catkin better. |
2013-07-12 19:53:11 -0500 | commented question | Qtcreator with Catkin I didn't say that - I'm well aware that catkin puts them outside the package directory. As I noted, the problem is that qtcreator is putting them in the wrong place relative to where catkin_make puts them, which means that the executables aren't used properly. |

2013-02-26 08:51:00 -0500 | commented answer | Set RViz camera/view on fuerte That's the easy way to do it, but it doesn't work if the user manipulates the UI, since the user can still change the camera view by hand and you can't get the new view back to change the transform. If you access the underlying Ogre camera, you can get information on the current camera viewpoint. |

2013-02-26 00:57:10 -0500 | answered a question | Set RViz camera/view on fuerte I'm not aware of any functionality built into RViz directly to do this. Our lab has been working on-and-off on adding programmatic camera support and it (as far as we can tell) involves building a new view controller class and recompiling RViz. We hoped there would be a way to do it using plugins, but the only way to directly access the necessary Ogre camera object is using a special view controller. |

2013-02-23 17:31:18 -0500 | asked a question | OpenNI devices and USB 3.0 None of our OpenNI devices (Kinect, Xtion, PrimeSense Carmine) work when attached to USB 3.0 ports on our computers running ROS Fuerte and Ubuntu 12.04. These computers all have either NEC/Renesas uPD720200 controllers or Intel Panther Point (integrated in the chipset) controllers. Has anyone successfully used these sensors on USB 3.0 ports? |
2013-02-23 17:21:29 -0500 | asked a question | Kinect not recognized by OpenNI drivers Our lab recently got a PrimeSense Carmine sensor, which isn't supported by ROS Fuerte's OpenNI drivers. We followed the suggestions of a previous ROS answers post, which added support for the Carmine but appears to have broken support for the Kinect. When we run openni.launch using the Kinect, we get the following error: The Kinect, however, is clearly visible to the operation system (Ubuntu 12.04): Has anyone gotten all of these sensors to work simultaneously under ROS Fuerte or ROS Groovy? |
