| 2014-01-28 17:28:56 -0500 | marked best answer | How to know which object roboearth is seeing Hi! I'm new with roboearth. I've already created some models in my computer and I have also succeded when trying to detect the object. The problem is: when I load different models and I put the detector to work, is there any way to know which object is being detected? I mean, is there a service/node/something that says "I've detected a box", "I've detected a can", etc. ? Any help is welcome! Thanks! |

Somewhere along the line, I have to use the command E: Unable to locate package python-rosinstall. If I try the command sudo: pip:command not found. What should I do? I'm a beginner, so any help is welcome! Thanks! EDIT: After michikarg's help, I was able to run rosinstall but I'm still having problems with the installation process.

| 2013-11-14 04:29:39 -0500 | asked a question | ar_pose on ROS Hydro Hi everyone! I've been using ar_pose on ROS Fuerte for some time, but I want to update and start working with ROS Hydro. However, ar_pose doesn't work when using Groovy and Hydro. Is there any update or any changes that should be made in order to have it working? Thanks! |

| 2013-06-07 00:17:31 -0500 | marked best answer | Can't get correct position of ARMarkers Hi everyone! I'm using ar_pose to identify some markers. It identifies the markers correctly (pattern 1, 2, etc.), but their positions are not very good. The distance is not being correctly assigned. I guess this is not ar_pose's problem. See the image below:
Could it be a depth_registration issue? Also, I tried calibrating my camera (kinect) following these tutorials: If couldn't make myself clear, please, tell me, so that I can explain it better. I would really appreciate if someone could help me! Thanks! |
| 2013-06-06 04:53:19 -0500 | asked a question | Pioneer3-AT Rviz/urdf model Hi everyone! I am running a SLAM simulation using a Pioneer3-AT and it would be usefull if I had the pioneer's model on Rviz. That is, is there a way or a place where I can get a model of the P3-AT running on Rviz (urdf?) ? My objective is to have the real pioneer working on real world and a "picture" of him running on Rviz (in the same position as my "\base_link"). I know there is p2os_urdf, but the model it gives is not exactly the one I want. Is there an easy way to edit this model into the one I want? Thanks in advance! |

| 2013-04-23 04:20:01 -0500 | marked best answer | Getting image_color from camera1394 Hi everyone! I'm trying to get the image from my Fire-i400 1394 camera. In order to do that, I am using the following comands: $ rosrun camera1394 camera1394_node $ ROS_NAMESPACE=camera rosrun image_proc image_proc $ rosrun image_view image_view image:=camera/image_rect_color and this should give me the images, with color. But I'm getting the following message: Color topic '/camera/image_color' requested, but raw image data from topic '/camera/image_raw' is grayscale then, the images come up, but they are on grayscale. Does anybody know why it is happening? What am I doing wrong? Thanks in advance! |
