how to run this program?

[3bobo]

hi, your work is nice. thus I want to have a try . I have maked this successfully, but I'm failed to have the result as you show in ros wiki
I first
roslaunch ipa_room_segmentation room_segmentation_action_server.launch and roslaunch ipa_room_segmentation room room_segmentation_action_client.launch,
and then
roslaunch ipa_room_exploration room_exploration_action_server.launch and roslaunch ipa_room_exploration room_exploration_client.launch
but I get this:
segmentation:

exploration:

how to get the result as you show in the ros wiki page ?
thanks for your help! and Sorry for mistaking the place of this issue first time!

Hello,@cuiyubo,I'm compiling this project recently,but when I Linking CXX executable catkin_ws/devel/lib/ipa_room_exploration/room_exploration_server,I have encountered some errors look like this:
flow_network_explorator.cpp:(.text+0x21f4)：‘GRBModel::addVar(double, double, double, char, std::__cxx11::basic_string<char, std::char_traits, std::allocator >)’ undefined references.
and so on .
I use Cbc-2.9.8 version and gurobi702 version for this program,but I don't konw whether it's correct version or not. So I want to ask you how did you compile ipa_room_exploration package?And which packages are needed?And thanks for your help!

楼主您好，我在编译ipa_room_exploration这个包的时候遇到了一些问题想请教你一下。我在链接room_exploration_server可执行文件的时候遇到了关于GRBModel一些未定义引用的问题，看起来像是一些lib没有链接上。我用的是Cbc-2.9.8版本的包还有gurobi 702版本的包来进行编译的，Cbc-2.9.8我没有安装在urs/目录下面，而是在外部编译，修改了PKG_CONFIG_PATH变量导入，gurobi是安装在了opt文件夹下面。所以我想请教你一下：你是用了哪些版本的包进行编译的呢？具体的安装位置是什么地方呢？希望能够得到您的指点，不胜感谢！！

@Irving87 I'm sorry to tell you that I gave up using this code long ago, and I even deleted them from my computer. I just remember that I built them in a workspace for catkin, and used sudo apt-get install XXX if something was missing. I used indigo branch if I‘m not mistaken, and the package was in catkin_ws/src/.

@3bobo Thank you for your reply, these information may be very useful to me,thanks a lot!

Hello, I wanna ask you about ipa_room_exploration, I started server and client, after that, I got generated path and it was shown in Rviz like on the picture.

The path appeared in Rviz but the robot doesn't move. So how can I launch moving a robot? And did you solve the problem, that the path going through the unknown area?

@Irving87 Have you solved the problem about GOROBI? I met the same error with u

Hello, I had a problem with Cbc library, I tried to install it like third-party lib.
I solved this problem, just installed this lib from ubuntu pack, you can try these commands:
sudo apt-get install coinor-libcoinutils-dev
sudo apt-get install coinor-libclp-dev
sudo apt-get install coinor-libcbc-dev
sudo apt-get install coinor-libcgl-dev

sudo apt-get install ros-kinetic-cob-extern

roslaunch ipa_room_exploration room_exploration_action_server.launch
rosrun ipa_room_exploration room_exploration_client

@daalexan Thank you for the answer. My previous question was that I haven't installed the ros-kinetic-cob-extern. Thanks a lot !
By the way, which version of OpenCV do you use?

[daalexan]

OpenCV version 2.4.9.1

Hi, I got the path after I run the ipa_room_exploration. I wanna know that how to show the path I got in Rviz?

Hi, I got the path after I run the ipa_room_exploration. I wanna know that how to show the path I got in Rviz?

Hi, at first I launched Rviz and add to Displays window Path, after that you should choose the topic which was generated by ipa_room_exploration and start ipa_room_exploration, the path will appear in Rviz.
You can launch ipa_room_exploration and check which topic it generated after that add that topic to Rviz.

[ipa-rmb]

I think moving the robot should work (at least worked for a colleague who used a robot with standard move base interface) when activating this option:

autopnp/ipa_room_exploration/ros/launch/room_exploration_action_server_params.yaml

Line 34 in b432c80

execute_path: false

Otherwise, take the returned path from the response message and execute it with your robot.

[ipa-rmb]

For the displayed path in RViz I guess, that the lines through occupied space just connect two path points before and after the occupied area with a straight line, so this is just a problem of visualization, not path planning.

roslaunch ipa_room_exploration room_exploration_action_server.launch
rosrun ipa_room_exploration room_exploration_client
I have run these commands, and this is the version of these packages:

But I still get many errors like this when I run :cathin_make

flow_network_explorator.cpp:(.text+0x21f4)：‘GRBModel::addVar(double, double, double, char, std::__cxx11::basic_string<char, std::char_traits, std::allocator >)’ undefined references.

what's your version of these packages?
And the CMakeList.txt shows:
Important note: the order of the libraries when linking your executable is important, if it is wrong you get undefined references
what's your order of the libraries?

[SidharthSitimalle]

How to install the package in linux?
when i run roslaunch ipa_room_segmentation room_segmentation_action_server.launch
its showing an error that ipa_room_segmentation package is not available
ipa_room_exploration
