Hi @LuukBerkel , Thanks for the reply and the solution......Appreciate it a lot!!!! But after i change the code in logged_waypoint.py as mentioned above and run the following command :
I am getting the following error :
But when I run : The service is availabe Could you please help me with this ?? |
|
I compiled robot_localization from source from the ros2 branch at Robot Localization Github, instead of installing it using apt. I don't know if there is a big difference but could you try that. |
|
Hi @LuukBerkel , How did you install robot_localization from github??When i `Starting >>> robot_localization Could not find a package configuration file provided by "GeographicLib" Add the installation prefix of "GeographicLib" to CMAKE_PREFIX_PATH or set Failed <<< robot_localization [3.60s, exited with code 1] |

Hii @LuukBerkel , I tried doing what you suggested above ......But i am still getting the same error :
|
Did you source it. Just to be sure. Maybe you could try to remove the apt version. And i will check basic navigator of my self to check if i modified some thing. I will come back on. |
Yeah I removed the apt version of robot_localisation and sourced the workspace too..... Thanks for the reply and take your time!! |
|
When I do the following part of the tutorial: I get the following error: As a result nav2 doesn't seem to start (it's inactive) and when I send a goal the robot doesn't move how did you solve it? |
|
I'm trying this demo on humble too and have some error running is this errors related to humble vs iron distro? Thank |
Hii @LuukBerkel , Any updates regarding this?? |

Hii @ghoenicka Could you please tell me how did you achieve this . What all changes did you make? Did you just change the logged_waypoint_follower.py ? Please help me !!! |
|
Cant' you just install ros iron? It works pretty well on it. Or even using a docker container? I'm doing that waiting for a solution on Humble ... |
|
I tried using the docker but found no success |
Just in case you want to give it a try again: ros_entrypoint.sh put the files on a folder and run: After it finished you can run: it will start 4 WP stored on the demo yaml file. BTW I'm on Windows 11, running ubuntu 22.04 on WSL and inside it using Docker.
Hope this help! |
Hi @ZaBy10 .. I been followed this official tutorial from Nav2 (https://navigation.ros.org/tutorials/docs/navigation2_with_gps.html) with the only difference is I have a custom robot (not the turtle bot). When I reached the GPS navigation, I found the problem with the difference between HUMBLE and IRON ( explained here: cra-ros-pkg/robot_localization#844 ) , I do the changes on my distro files ( /opt/ros/humble/lib/python3.10/site-packages/nav2_simple_commander/robot_navigator.py ) and finally found this thread with the problem on followGpsWaypoints(wps)... I applied the changes on interactive_waypoint_follower and logged_waypoint_follower. .. It's start working !! .. but.. with the problem of the all values returned are '0' .. but I think that is a problem with my frames of references.. (still working to find this solution) try to see the logs of the ROS every time that you run some launch.. because I noticed: if there is a problem for example loading the gazebo, you will not have any problem when is running but you will see only a small line with the tag 'ERROR'.. that's happens to me a loot. Bad parameters .. |

Thanks a lot @LuukBerkel @ghoenicka , it finally worked !!! @ghoenicka is it working on a real robot? |
I will tested on a real one by March. I hope that will work with out problem. |
I have solved this problem on humble. You should pay attention to the plugin _ lib _ names in this file nav2_no_map_prams.yaml: lines 32, 41, 42, 43, 44, 61 and 76. Just comment out these nodes. |

hi all, Clearly this is a very in demand feature. devs, would you consider properly back porting this to humble? I'm running this on a Jetson and I'm running into issues with not every package being supported on aarch64/arm64 for iron. A backport would make life much easier. Thanks |
Hii @ghoenicka , Did You test it on a real robot ?? what was the result , please share!!! |
Hey.. not yet.. we made some changes in the plans.. but we hope at end of this year see it running in the first prototype.. |
This is probably because you're unable to transform GPS coordinates to your local coordinate system. Are you sure that your GPS localization system is up and running? I.e. can you get the transform from |
Hi @yishaiSilver .. I already fixed this. was a problem with the system definition of my robot between gps frame and the base frame. |
|
@LuukBerkel Your code seems to be working great, thank you. That being the case, I seem to be having trouble with the ToLL service, despite it working with terminal. Is there something I'm missing (asides from obvious changes, i.e. FromLL -> ToLL)? Update: Nevermind, I was spinning my node with |
|
Just writing that I think the spin() function from LuukBerkel incorrectly calls Otherwise the code looks great. |
Hi @ghoenicka, How did you solve for having all poses set to (0,0,0)? I have run into the same problem that the GPS point I provide is always converted to (0,0,0) position value and thus the robot doesn't move. |
