2013-08-09 10:39:26 -0500 | commented question | ROS fuerte PCL tutorial problem If you are doing the Point Clouds 2 part of the tutorial where you are applying a voxel grid filter then yes, it does publish data that you can view through rviz, just add a new Point Clouds 2 and set the topic to /output |
2013-08-07 08:14:01 -0500 | commented question | ROS fuerte PCL tutorial problem So everything with the ros pcl tutorial is working fine? That's good to hear. I don't understand what your question is, if the problem is that you are seeing a black box in the space where there is supposed to be a video the you probably need to update your flash player or something as they should be working fine. If that doesn't work, try a different browser or if your using ubuntu in a virtual machine then try using a browser outside virtual machine. |
2013-08-06 05:44:51 -0500 | commented answer | ROS fuerte PCL tutorial problem For future problems, a very helpful way of debugging in ros is using rqt_graph, it helps you understand what exactly is happening in the background (is the program subscribed correctly to all the inputs? does it publish everything correctly? if using a series of nodes, where do they stop working? etc...) |

2013-08-06 05:35:44 -0500 | answered a question | ROS fuerte PCL tutorial problem Hi, what exactly do u mean it's not working, does it give you a specific error? does it have no output? Here are a few common errors people do while using this tutorial:
If none of these are your problem then please give us some more information so that we may be able to understand your problem better. |

2013-07-22 12:09:14 -0500 | answered a question | PointCloud to LaserScan Kinect It turns out VirtualBox was causing everything to not work properly for some reason. Now I'm using VMware and everything's running fine. What confused me was that I was getting errors that I found online and that even after trying every fix I could find some would still be there. Next step is getting XYZ coordinates of a moving robot, I'll start looking for tutorials right away (I'm still new to ros). |
