I am having issues with the head camera of the Stretch3. The issue is that the camera is not seen as a realsense camera: I get the error “The requested device with device name containing d435 is NOT found.” when launching d435i_low_resolution or multi_camera. Moreover, the command rs-enumerate-devices only shows the gripper camera.
However, I am able to see the video stream with I run stretch_camera_streams_check.py
The strange thing is that with realsense_viewer I can see the gripper camera by default but then I need to add the head camera separately which is listed as a ‘Platform Camera’ and not as a realsense one. For further info, stretch_system_check.py fails on the D435 camera.
Thank you for your post. Based on your description, it might be a loose or damaged cable. Could you please email support@hello-robot.com with this description, your robot number and any logs you’ve collected, so we can help you resolve this? Thank you.
Today though I have this issue> [ERROR] [head]: SerialException(2): could not open port /dev/hello-dynamixel-head: [Errno 2] No such file or directory: ‘/dev/hello-dynamixel-head’
HW Not Valid
Any ideas of what could it be? Systems check cannotbe run because of this.
As a follow-up to the previous message, could you please run the following debugging steps so we can further investigate the hello-dynamixel-head issue?
Start by power cycling the robot.
Run REx_discover_hello_devices.py --list and share the output with us.
Run cat /etc/udev/rules.d/99-hello-dynamixel.rules and share that output as well.
Thank you again for your patience, we’ll continue to work with you until this is resolved.
