2015-11-20 15:58:17 -0500 | commented answer | Multi-robot exploration with explorer and adhoc_communication? Hi Micha, thanks for your answer! With that launch files i get exactly the same results as with my files. Are you sure the robots explore in a coordinated way on your machine? I am adding some information in my question above since the space for comments is limited. |

2015-11-14 06:54:48 -0500 | asked a question | Multi-robot exploration with explorer and adhoc_communication? Hi , i am trying to setup a multi-robot-exploration like shown in the video of the explorer package (http://wiki.ros.org/explorer). Did someone successfully get that setup running? (explorer + map_merger + adhoc_communication) Here is what i got so far: I started with files from https://github.com/OSLL/aau_multi_robot, which is a fork of the aau-ros/aau_multi_robot repository containing some new launch files. If i run my launch file, based on them, the 2 robots start exploration, but in an uncoordinated way. I then read a bit in the source code and found a comment stating that the robot names have to be added to the source code (in explorer.cpp at line 103 of the explorer package). I added my robot names and recompiled explorer. but unfortunately that doesn't change anything. Last thing i found was a commented Preprocessor directive #define JOIN_ALL_GROUPS (in define.h of the adhoc_communication package), which activates a code block (in adhoc_communication.cpp at line 1208) in which this adhoc_communication node tries to join all existing multicast groups. I uncommented this directive and compiled adhoc_communication again. Then i get error messages (from adhoc_communication) like this: and from explorer i get warnings like: So i guess i configured something wrong with the adhoc_communication package. Any help would be appreciated. Thanks! Here is my current launch file (aau_multi_robot_simulation is a package i created containing parameter and configuration files; i don't think the problem is related to them, so i omit them): (more) |

2015-06-17 09:26:21 -0500 | asked a question | "fatal error: 'QMetaType' file not found" when building ROS Indigo on OS X 10.10.3 Hi, i did first tests of ROS under Ubuntu and now i want to install ROS Indigo on a MacBook Pro with OS X 10.10.3 according to http://wiki.ros.org/indigo/Installati... . Unfortunately i get an error in the last step ($ ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release): fatal error: 'QMetaType' file not found I think i only have to set a variable like $PATH or something, but i don´t know which one (or in which file i have to state the path) (i found a qmetatype.h in /usr/local/Cellar/qt/4.8.7/lib/QtCore.framework/Versions/4/Headers/qmetatype.h) Sorry for my obvious lack of knowledge so any help would be appreciated. Thanks a lot. Here the terminal log of the error: (more) |
