The node name must not be empty #35

Which launch file do you use? |
|
I'm using pepper_full.launch from this repo |
|
But the namespace is set by default to "pepper_robot" in this launch file, no? |
|
Yes, and if i use this command |
This is the output i'm getting when I try to launch pepper_bringup.launch (I use this repo and naoqi_driver compiled from source). |
|
This problem is related to this issue : |
|
it is working on my machine, please check your package version by running |
And I'm using ROS Kinetic EDIT: |
|
Did you compile it from source or installed with apt-get? In any case, for both source and release, it works on Kinetic with Python version, I've just tested it with 2.5. Please try to launch it like this: roslaunch pepper_bringup pepper_full_py.launch |
|
I tried both and had the same error (with apt-get method and compiled from source). Thanks, python version works but i was interested in the C++ bridge. |
|
I just commented on the referenced issue. ros-naoqi/naoqi_driver#73 (comment) I think this is a bug and should be changed. @PacoDu do you mind opening a PR against it? I can't test it on my side due to lack of robots. It should at least warn you correctly that you try to pass an empty name to |
|
Sorry for the delay I was digging inside roscpp and naoqi_driver before proposing a PR. I temporary fixed the issue on my side by adding a fixed node name in ros::init (as proposed by ros-naoqi/naoqi_driver#81) and I was looking for a way to avoid duplication in topic name (c.f. pepper_robot/pepper_robot/). |
|
I have the same error with ROS Kinetic. @PacoDu , have you found a way to avoid the duplication in the topic name? |
|
Yes I can publish my code, i'll upload it has soon has i can. It need some cleaning. |
|
Thanks @PacoDu ! I will try it right now! |
|
It is working fine for me! Ubuntu 16.04, ROS Kinetic Merci @PacoDu |
|
Just fixed some remaining line in naoqi_driver (setPrefix) before prefix value verification that I missed in the merge. |
|
Should we close the issue then? |
|
Ok for me, It would be useful to merge the pull request. Is the fix working also under Ubuntu 14.04 and ROS Indigo? If needed I could test it. |
|
the fix should not be needed on indigo given that raising on empty node name has been introduced in Kinetic and not backported to Jade or Indigo. (c.f. ros/ros_comm#894 (comment) and ros/ros_comm#895 (comment)). It would be good to confirm that it doesn't break anything though. |
|
I didn't have the time to test the fix on ROS Indigo, it would be great if you can confirm that it works @jokla Thanks ! |
|
Tested under Ubuntu 14.04 and Indigo using the pull request #40 in pepper_robot , it's working! |
|
This is still not merged? I had the same issue, but the fix above worked for me. |
|
I'm still facing the issue on launching pepper_full.launch, even after applying #40 in pepper_robot. Any help? Using ROS Kinetic, Ubuntu 16.04, compiled pepper_robot and naoqi_driver from source. |
|
@metalaman please, do "git pull" in "pepper_robot" and try again. |
|
Hi, @nlyubova Thanks, I fixed the issue, could you also tell me how to visualize point cloud data, I'm running |
|
Try to set the "global frame" in RViZ to base_link |
|
Hi @nlyubova I tried the fix, it isn't working. My pepper_bringup console log shows me the following warning, |
|
Hi, was finally able to get the point cloud. Thanks a lot for help. |
|
To make it faster, use /compressed image topic for rgb The difference in quality is not visible, and the speed is much faster. |
|
And turn off the bottom camera in boot_config if you are not using it. |
|
In share/boot_config.json And you can take smaller resolution to make it faster |
|
I'll try those, Thanks again. |
Hi, i'm using Pepper Naoqi OS 2.5.5. Trying to use roslaunch pepper_bringup fail with this error :
what(): The node name must not be emptyAfter some digging I've identified that this is due to the namespace from pepper_full.launch
<include file="$(find naoqi_driver)/launch/naoqi_driver.launch" ns="$(arg namespace)" >Removing
ns="$(arg namespace)"fix the error but naoqi_driver is not starting under /pepper_robot/ namespace.Looking at naoqi_driver src, the error comes from this line:
boost::shared_ptr<naoqi::Driver> bs = boost::make_shared<naoqi::Driver>(app.session(), vm["namespace"].as<std::string>());and is raised whenbs->setMasterURINet( "http://"+roscore_ip+":11311", network_interface);is called.vm["namespace"].as<std::string>()is empty. I'm new to ROS but for what i've understand, starting the module in a namespace create some conflict if the node doesn't have a prefix, if there is no namespace everything work normally and the node start properly.Note that this seems to affect the camera module essentially (no data in rviz for example, even if I bind the camera data to
/naoqi_driver_node/camera/front/image_raw/).The text was updated successfully, but these errors were encountered:
