Technical Support & Q&A Advanced

Dear,

Does any body try like this combination?

  • 4 x Astra 3D camera
  • driver pkg: astra_camera - ROS Wiki
  • NVIDIA Jetson Xavier NX devkit (aarch64)
  • OS: Ubuntu 20.04
  • ROS: Noetic

What happened:

  1. when connecting 4 x Astra cams on the target, lsusb can show everything

  2. ros launch for each cam
    $ roslaunch astra_camera astra.launch
    when creating 4th cam, ROS core crashed

  3. multi cam
    $ roslaunch astra_camera multi_astra.launch
    when launching multi_astra.launch, ROS waits some cam permanently.
    And IR indicating Red LEDs do not ON at random Cams.

To figure out power feeding issue, I used a powered USB 3.0 hub.

Hope your help and thanks in advance
