2014-02-26 00:51:14 -0500 | answered a question | Assertion Failed when trying to publish on a ROS topic I had the exact same problem when running this code here (On Fuerte) It worked for me when compiling yarp with the standard CMakelist settings. ( Before I used the instructions here http://wiki.icub.org/wiki/YARP_ROS_In... ) Cheers, Andreas |
2014-01-28 17:26:20 -0500 | marked best answer | Time Synchronizer with more than 9 incoming channels Hi, I need to synchronize 32 image topics, which then trigger one common callback function. Unfortunately message_filters::TimeSynchronizer only supports up to 9 topics, and so does message_filters::sync_policies::ApproximateTime. I found a note to a DynamicTimeSynchronizer in the source code, but apparently it's not implemented yet. Is there an easy solution / workaround? Cheers, Andreas Btw: Is there a reason why the number of topics is hard coded? |

Any ideas? Cheers, Andreas |
2014-01-28 17:22:42 -0500 | marked best answer | roscpp relative parameter Hi, I somehow can't manage to get or search relative parameter names. What I do is, I launch a launch file which sets parameters. This all works, I can get and set parameters using rosparam via the shell. They are published over e.g. /test_node/orientations, /test_node/kernels/kernel_1/wavelength, /test_node/kernels/kernel_2/wavelength and so on. Now within the test node I want to read those parameter. But when I try The parameter won't be found, I have to explicitly name the whole global name "/test_node/orientations". I have the same issue with Am I doing something wrong? Is there a way to get the current namespace the node is in as a workaround? (I'm using Ubuntu 10.04.1, 64 bit with the standard ros diamondback package from the package manager) |
2013-09-20 01:40:29 -0500 | answered a question | uvc_camera not launching in ros groovy. There is no uvc_camera package included in groovy, I don't know why. It appears again in hydro. However there's a package in the repository called ros-groovy-usb-cam. Install, then run "rosrun usb-cam usb_cam_node" Alternatively you can also use ros-groovy-gscam (http://wiki.ros.org/gscam). (Related question and more detailed answers: http://answers.ros.org/question/57320/package-for-simple-usb-web-camera-in-groovy/) |
2013-06-25 23:17:50 -0500 | marked best answer | Eclipse ROS fuerte Hi guys, I did exactly as described here http://www.ros.org/wiki/IDEs to import my ROS package to Eclipse. It compiles and runs without problems using the shell, but when using "Build Project" in Eclipse I only get: I don't see where the problem is. I checked the environment variables and they are fine.

2012-10-02 04:31:10 -0500 | commented answer | Synchronization with 8 incoming channels, registerCallback boost::bind -> compilation error Or maybe is it possible to somehow use registerCallback without bind? |
2012-10-02 04:27:12 -0500 | commented answer | Synchronization with 8 incoming channels, registerCallback boost::bind -> compilation error It works with 6 and works with 7. I will try it with the functor object, or just split the callback up to twice four channels. Thanks! |
2012-10-02 03:55:42 -0500 | commented question | Synchronization with 8 incoming channels, registerCallback boost::bind -> compilation error As I just added, might it be possible, that the problem is occurring due to boost 1.46 and not 1.48? |
2012-10-02 03:43:53 -0500 | commented question | Synchronization with 8 incoming channels, registerCallback boost::bind -> compilation error Ups sorry, just changed it. |
2012-10-02 03:34:13 -0500 | commented question | Synchronization with 8 incoming channels, registerCallback boost::bind -> compilation error complete error message added :) I hope it helps. |
2012-10-02 02:57:03 -0500 | edited question | Synchronization with 8 incoming channels, registerCallback boost::bind -> compilation error Hi all, UPDATE: I found a workaround which I posted at the end of this question I try to use ApproximateTime Synchronization with 8 channels, but I get a compilation error. Strangely it works with 4. Here's some of the code: (The error is at sync_->registerCallback(boost::bind(&S2::filter_image, this, _1, _2, _3, _4, _5, _6, _7, _8, "ok")); ) The error I get is: (more) |
