I manually set has_gyro = True (or False) but either stucks here.

Thank you so much! I got the rgb camera calibrated using the camera_calibration tool, but I cannot find how to calibrate the depth camera. It looks depth sensor is also way off now.

I am having the same problem. Can someone shed a light for a noob?

Hi,

Where can I find depth_Astra_Orbbec.yaml file? I googled it but doesn't seem it is available anywhere. I am using Astra camera, and I see these warnings.

I am trying to debug why the amcl doesn't work. Any clue?

Awesome. Thank you!

Is there any design doc or research papers that the current turtlebot navigation stack implements? I would like to learn the algorithms and the top-level design in more depth. Thanks!
