Hi,
Whenever i try to run
ros2 launch stretch_nav2 offline_mapping.launch.py
From Nav2 documentations, i am not able to see the map in RVIZ.
The error i am facing is under
GlobalStatus: Error
FixedFrame: Frame [map] does not exist.
Can anyone help me with overcoming this problem?
Thanks.
Hi @Yash welcome to the forum.
Could you provide the whole error output from the terminal for further debugging?
I’ve ran code from stretch_install to update the workspace. Now everything seems to be working fine.
How ever, i noticed that when the funmap or the Nav2 is launched, the Xbox controller does not respond. When the controller is off, the Funmap and Nav2 works perfectly fine.
How do i debug this?
Thankyou for reporting this issue. I am trying to reproduce the issue and will get back to you soon.
Here are a couple of screen shots from the terminal when i ran it.
Sometimes, when the Controller works, i dont see the nav2 map that is being created ( as in the original Image of the query post).
When i run it again after freeing the controller, Nav2 and Funmap works perfectly fine.
I am not able to use the controller and have to depend on the keyboard navigation.
I tried running the controller code after launching the Nav2, it says some other process is using the controller and i need to use the stretch free script.
I recently tired running rtabmap and it worked well with the stretch robot.
Unfortunately, the same issues of Remote Controller still exists with it.
I do have a more questions about the Device and its working. I would be using the Stretch Robot to capture images using DSLR camera and would require some guidance with it.
Should i create a new forum post or shall can i post about them over here?
Hi @Yash sorry for the delayed reply. The issue you are seeing with the xbox controller seems like an USB port access issue between the stretch_driver node and teleop_twist_node. Stretch driver got introduced a new gamepad mode which is trying to access the Joystick USB and at the same time telelop_twist_node might also be trying which might be causing trouble.
I have created a fix branch for you try which removes the teleop_twist_node launch and launches stretch_driver in gamepad mode. Would you try this fix branch and see if the issue goes away?
And regarding using Stretch with DSLR camera, please feel free to start a new forum with more info on the project and things you are trying to achieve. Happy to help with it.
