moon-wreckers / vive_tracker Goto Github PK

After setup according to the guide, I got an error:

An exception of type OpenVRError occurred. Arguments:
('VRInitError_Init_VRClientDLLNotFound (error number 102)',)

How did that happen?
It seems the node can not find openvr library.

HI i am using this package, and when i launch it, i get this error

[vive/vive_tracker-5] process has died [pid 13767, exit code 1, cmd /home/vkguda/catkin_ws/src/vive_tracker/scripts/vive_tracker.py __name:=vive_tracker __log:=/home/vkguda/.ros/log/533df952-967e-11e9-a264-34e12dcd93f8/vive-vive_tracker-5.log].
log file: /home/vkguda/.ros/log/533df952-967e-11e9-a264-34e12dcd93f8/vive-vive_tracker-5*.log

any reasons why i get this error?

I've tried with two base-stations and tracker with no issues. Attempting to use one base station set to "A" and the tracker is not working. Both devices show up in steamVR but have status of not tracking. Any guidance on this?

ROS quaternion notation is [X, Y, Z, W]. Wonder why it works this way.

Hi, I am facing a problem. I am using Python 3
When I run the code, this error shows up: AttributeError: 'str' object has no attribute 'decode'
I googled it and it seems here we don't need the decode more. I then deleted it, but then a new error showed up:
Traceback (most recent call last):

How do I fix it?
Thanks it advance

Can you add the MIT license to your repository?

The MIT license is already in the package.xml but it would be nice for everyone to see it directly when you open the repository.

Hi,
I am looking to migrate the node as a ROS2 one due to better dependencies with openvr and python 3. I was looking into the TF transformations however they are not that clear to me. Could you explain me how you define map, odom, vive_world and vive_tracker?
Thanks

Best,
Matteo

Hello,
I am trying to use this repository to use vive tracker with ROS and keep on getting errors.
I am using ubuntu 18.04 with ROS melodic.
As you know ros melodic uses python 2.7 and thus keep on giving me this error when I

roslaunch vive_tracker vive_tracker.launch

I tried to switch my default python interpreter to python3.6 but it also didn’t work.
I also tried to use openvr 1.3.2201 which also gave me the same error...
I was wondering how you managed to run the files. Did you use python 3.5+ as ROS’s interpreter? Or am I doing something wrong?
I have been stuck here for so long.. I hope you can help me.
Thank you in advance!
