EI-AMR: Follow Me Demo Not Installing Correctly

[ChrisMatthieu]

Hello

I'm trying to run the Follow Me demo from the Intel Robotics SDK link - https://amrdocs.intel.com/docs/2.0/dev_guide/tutorials_amr/navigation/follow_me/followme-with-gesture.html#run-demo-with-realsense-camera 

I seem to be having trouble installing:

sudo apt install ros-humble-followme-turtlebot3-gazebo

Here’s my log file with errors:  https://gist.github.com/chrismatthieu/d93efa01a6c471a0addb44333c9d7b1c 

Could you let me know if you see any issues or have any advice?

Note: I am able to run the demo in 3 terminals but it seems to be having trouble identifying me...

Thanks in advance.

Hi,

You are referring to an older version of Robotic SDK tutorial.

It is recommended to follow this latest tutorial (version 2.1) instead, which utilizes ROS 2 components. 

Cordially,

I reinstalled everything (V2.1).

When I run the first follow me tutorial (without gesture recognition (https://amrdocs.intel.com/docs/2.1/dev_guide/tutorials_amr/navigation/follow_me/Tutorials/followme-on-aaeon.html#run-demo), everything seems to run but ends abuptly with a ros2run: Segmentation fault.  See attached.

I seem to have better results with the follow me with gesture recognition tutorial (https://amrdocs.intel.com/docs/2.1/dev_guide/tutorials_amr/navigation/follow_me/Tutorials/followme-with-gesture-on-aaeon.html#run-demo-with-realsense-camera). No errors but it never seems to recognize the thumbs-up or thumbs down gesture; therefore /cmd_vel is always reporting 0 on all twist properties.

Three questions:

1. What could be causing the segmentation fault in the first demo?

2. What could be causing the gesture recognitions to fail?

3. Is there a way to run the second demo with without the gestures?

Thanks,

Chris

Here's my terminal output: https://gist.github.com/chrismatthieu/ed435f584cb0db865db8d094427a2da5

Looking through the above logs, I see these messages related to gesture:

Custom gesture classifier is not defined.

From the image that you shared, it seems that the issue originates from your camera (Realsense) setup.

We'll further investigate this and get back to you with possible workaround.

I resolved the issue by commenting out the Aaeon robot controller (as it does not exist on my custom built robot) and reduced the complexity from 2 cameras to 1 camera in the bash script.

Hi,

Intel will no longer monitor this thread since this issue has been resolved. If you need any additional information from Intel, please submit a new question. 

Cordially,
