Hi - I am following the Web Teleop commands , I am able to control the robot motion through buttons on the web page , but the video feed is missing. How to troubleshoot that?
Hi @vipul , welcome to the forum! What Stretch version do you have (and, if Stretch 1 or 2, what is the wrist attachment)? The below instructions are for the Stretch 3.
The first thing to verify is that the cameras themselves are connected and working. To do so, access your Stretch via a GUI, by following the instructions here for either a “Tethered Setup” or “Untethered Setup.” Then, open your terminal and run stretch_camera_streams_check.py. This should load the Realsense and overhead camera streams. Close that and run stretch_camera_streams_check.py --d405 to load the gripper camera stream. If any of those video streams do not display, please reply here and I can help you diagnose it further.
If all the video streams display with the above commands, we know the cameras are working. The next step is to look into why the web app is not displaying it. Could you do the following:
- Launch the web app:
colcon_cd stretch_web_teleop; ./launch_interface.sh - Wait ~15 seconds.
- Attach to the screen session that runs ROS code for the web app:
screen -r web_teleop_ros - Enter command mode by pressing
Ctrl + a - In command mode, type:
:hardcopy -hand press enter. This should save a copy of the screen output to a file in the web teleop folder calledhardcopy.0. - Detach from the screen session. Press
Ctrl + ato enter command mode, and then pressdto detach. - Copy and paste the contents of the file here.
One I have the screen output, I’ll be able to better help diagnose why the camera streams are not displaying.

Hi Amal - stretch_camera_streams_check.py this command runs completely fine and all the camera frames are displayed on screen. Now I when I try to go to the web page it shows a message, Unable to connect. Here is the file you have asked for :

The issue appears to be with yaml parsing of the configure_video_streams_params.yaml file.
Could you send me the following info?
- What commit your web interface is on: Run
colcon_cd stretch_web_teleop, rungit log, and send me the hash of the top commit. - Have there been any local changes to
configure_video_streams_params.yaml? From the same folder, rungit diffand let me know if there have been any changes. - What version of
yamlare you using? Open Python withpython3and runimport yaml; yaml.__version__and send me the output.
- commit 20555d4e76670282e4097a19349efdcf6a8ccf36

I see your configure_video_streams_params.yaml file has some local changes. Were you attempting to develop within the stretch_web_teleop repository?
Firstly, I believe the error is due to a missing comma after the "mask": null line. Your file reads "mask": null but should read "mask": null, .
Let’s check whether the web teleop interface works with the original yaml file. In the stretch_web_teleop repo, run git stash. Then, rebuild the ROS2 package: cd ~/ament_ws; colcon build stretch_web_teleop. Then, try running the web interface again.
If it still does not work with the original yaml, please re-run the web app (with the un-changing yaml) and send me the output from the screen session (commands in the above message) and we can continue from there.
(Note: to recover the local changes, run git stash pop and then re-build the ROS2 package as outlined above.)
If you share your Stretch’s serial number (e.g., stretch-se3-<xxxx>) with us, we can also look into whether anything happened on our side to cause the local changes to the web app.
Note that another option is to entirely delete and re-install your ROS2 workspace. See instructions for that here.
Thank you @hello-amal for your quick response, Ultimately I had to re-install the ROS2 workspace and now things are working fine!
