2014-02-09 22:44:37 -0500 | commented answer | How to playback pointcloud in rviz which was recorded using rosbag Yes, rosrun rviz rviz after setting param true. What I do is,run as above, quickly set the topic, then run the bag again and the topic will show as expected inside rviz. You have a bag that was recorded for 2s - dont set the time and you can record as long as you like: rosbag record -O subset /topic |

2014-02-09 21:17:41 -0500 | commented answer | How to extract data from *.bag? I must be doing something wrong - I cant find where the file is saved? or is it just an oversight of mine that its not saving? |

2014-01-21 20:37:34 -0500 | answered a question | How to write PCD file from topic without loss data? This isnt an answer - its a hope that this question will be bumped again - When you do a $ rosrun pcl_ros pointcloud_to_pcd input:=/velodyne_points you get a bunch of .pcd's describing the scene. Is there a simple way of combining all of these (say 10s worth) of pcd files? |
2014-01-21 01:08:56 -0500 | commented answer | Rosmake: avoid rebuilding dependencies So - I find that running rosmake packagename --pre-clean helps sometimes when there have been errors, what would be nice is being able to skip certain dependencies that you know compile (and take the longest) and still use --pre-clean.. |

2014-01-17 01:41:28 -0500 | asked a question | rosservice call in bash causing issues Hi, I am trying to use bash to execute a bunch of rosservice calls, one after the other. Some work but the ones that ask for position ones don't: rosservice call /wam/cart_move "position:

2014-01-13 00:15:45 -0500 | answered a question | No kinect connected...waiting for devices to be connected... I have had similar problems before. The killall XnSensorServer typically works if you cant get your openni device running a second time (kinect or asus) but the "No devices connected.... waiting for devices to be connected" for me was a permissions issue with the usb port. So find the bus port that your camera is connected to and make sure that it has read write permissions. Edit: Solved!! I had to reinstall my libopenni - which I did through synaptic - now I dont get the error and I dont have to kill XnSensorServer every time I restart. |
