2015-04-23 16:02:27 -0500 | asked a question | How to create dependencies on specific version of a package Hi, recently I faced issues due to changes in rosapi version installed by standard ros installation command. In the new version the name of rosapi package executable is changed. Is there any way where I can specify external package version my package depends on? |

2015-02-05 21:51:35 -0500 | asked a question | How to add Python Modules into catkin libraries so they can be imported by other packages Hi, I want to create some python modules which are common for multiple ros packages. Can anyone guide me on how to list them in CMakeLists.txt file so they get insatlled in lib/python2.7/dist-packages directory? So far I have tried adding following lines This is giving me CMake Error as: Any Ideas? |
2015-01-27 23:37:52 -0500 | asked a question | rosmatlab subscriber synchronization with Main Thread Hi, I am using rosmatlab to read Lidar data published bu urg_node in Matlab. readScanData is a function which reads as follows: vectRangeData is a global variable which I used in Matlab Main Thread to analyses Lidar data. My question is how to synchronizes the access to global variable "vectRangeData"? As I understand callback function will be run in separate java thread using rosjava jars. After following link:matlab undocumented and inputs from senior developer I think they are using eval or feval functions to execute callback functions under subcriber threads. Still it confused me how to synchronize the access to global vars. I am not using Parallel Computing toolbox. Its just some objects shared between Matlab's Main Thread and Java Threads. |

2014-12-07 16:07:26 -0500 | asked a question | How to set single-echo mode on multi-echo lidar I am using Houyo UTM-30-LX-EW ethernet lidar scanner. Using urg node. I am able to publish scan data in ros. However, the scanner is running in multi echo mode. I want to run the scanner in single -echo mode. Does anyone know how to configure single-echo mode in urg_node? I am using ros-indigo on Ubuntu14.04. |

2014-10-28 14:16:20 -0500 | commented question | ResourceNotFound error with rostest absolute path to launch file Yes. I can run these packages individually as well with roslauch and rostest with package name. I trying to compare the source code for roslaunch and rostest to figure out the difference, just swamped with other tasks. |
2014-10-28 12:44:51 -0500 | commented question | seperate build and install target machines Yes. I have wrote a script to provide this functionality. One requirement for my script to work is to provide install rule for each package and run catkin_make install to build packages. If you need I can upload it in separate GitHub repo and provide link here. |

2014-10-22 19:41:54 -0500 | asked a question | ResourceNotFound error with rostest absolute path to launch file Hi, I have a bunch of "*.launch" files which starts different nodes on my machine. Since, these launch files are not specific to any package, I have kept these files in the catkin workspace directory. After running catkin_make and source devel.setup.sh I can run my launch file from anywhere just by supplying path to launch file. and it starts the configured nodes as desired. Now I am trying to add test tags to this launch file as well. I followed the wiki page rostest. However running the rostest as follows throws ResourceNotFound error. I am able to run the same test+launch file if I put it under src/<package1>/mylaunch.launch and run by Anyone can shed light on this problem?To me it seems to a bug. Because rostest should work similar to roslaunch. As per Dirk's advice updating the tracestack of exception The launch file |
