compiling and running

[xepost]

Hi, I downloaded your code and compiled under Ros hydro, but I couldn't find the proper method to run launch file. Roslaunch is asking for some input.Can you help me on that?

Bests,

Thanks for being interested in the project! Yes I know, the instruction in the readme are incomplete actually, but i'm about to write a more detailed version in these days (I have one already but it's in Italian), you will find it on the repository in a few days :) (Also, when I update the Readme, clone the repository again because I made a bunch of fixes lately that I haven't commited yet, like the unistd.h bug and more)

[fwanderlingh]

I've updated the repo. Check if you enconter any issues now! :)

Hello merosss, I am having trouble running this. I am not able to run the following command roslaunch quadcopter_ctrl swarmNodeCount_3.launch input:=map_file.txt

I get the following error. Could you help me with this please

I made a quick fix, try updating the repository and tell me if everything is now ok, because I cannot test right now.

[lightng03]

Thanks for the update ! Now the Pos_Vec matrix ierror is solved. but when the simulation runs V-rep shows an error.

Lua runtime error: [string "SCRIPT FastSimulationMode"]:18: attempt to perform arithmetic on global 'dlgStyle' (a nil value) stack traceback: [string "SCRIPT FastSimulationMode"]:18: in main chunk

I have attached a screen shot of the same

[fwanderlingh]

If you know how to edit the V-Rep .lua files associated to the scene you should edit it and disable the fast simulation mode. Otherwise I'll look into it and fix the bug asap. BTW, which version of V-Rep are you using?

[lightng03]

I am using V-rep Pro edu 3.2.3 rev 4 64 bit version and rosversion is Indigo. I am sorry I not good with .lua files, I am beginner. I'll try to edit it

[lightng03]

In the 3Rob_freeEnvironm scene, I commented out the line 18 in the FastSimulationMode. After this I am not getting any error but, when the simulation starts the screen goes black and returns to normal once the simulation is stopped.

[fwanderlingh]

Just delete the whole FastSimulationMode object by selecting it and pressing "Canc", I tried it on v-rep 3.2.1 EDU and it worked. Let me know

Hi Francesco!

Thanks for the help its working now I just tested out the swarmNodeCount3. Its working perfectly. Great work with the project. Ill test different scenarios and get back to you if i find anything

Cheers

[fwanderlingh]

Good! :smile: Closing the issue then

Hello, Like lightng03 I have some similar problems with your project. I did everything that you write above and I have errors like that:

process[OSListener-1]: started with pid [13493] process[quadNodeCount_0-2]: started with pid [13494] [0] My zHeight is: 5.000000 min_visit: 1 unvisitedCount: 11 quadNodeCount: /home/justyna/catkin_ws/src/quadcopter_ctrl/src/NodeCounting.cpp:114: void NodeCounting::createEdgeMat(): Assertionn == access_vec.size()' failed.`

so the swarm doesn't move. Could you help me with it?
