Problems on running Turtlebot2 Astra depth sensor
I am a new user on Turtlebot 2. For setting up the Astra depth sensor, I firstly downloaded the released package from here. I successfully finished the first two steps. When I did "roslaunch astra_launch astra.launch", there was a warning in the terminal which said "USB events thread - failed to set priority. This might cause loss of data........".
As a result, in the rviz, I cannot receive any data from the following topics:
/camera/rgb/camera/depthregistered/swregistered/image_rect
/camera/rgb/camera/depthregistered/swregistered/imagerectraw
/camera/rgb/camera/rgb/image_raw
/camera/rgb/camera/rgb/imagerectcolor
Sometimes, there will be other warnings shown in the terminal, such as "Unable to open camera calibration file [/home/turtlebot/.ros/camerainfo/depthAstraOrbbec.yaml] ", or "Camera calibration file /home/turtlebot/.ros/camerainfo/depthAstraOrbbec.yaml not found."
After adding the PointClound2 in rviz, I could receive the data from /camera/rgb/camera/depth/points, and shown in the simulator, but there was still a red status:error. Besides, I could not receive the data from topic: /camera/rgb/camera/depth_registered/points, in the meantime, a warning said "Messages of type 1 arrived out of order (will print only once)".
Can anyone help me on this? Thank you very much!
