I am using an official workshop

https://jp.mathworks.com/matlabcentral/fileexchange/91980-matlab-ai-robotics-workshop

If I use Constnt value, I can rotate the motor via ROS, but I cannot operate the GUI at the bottom right. Also, the image from the camera does not appear on the video display.

Thank you for trying the workshop content. Regarding the GUI, did you see any errors on your MATLAB command window?

I appreciate your prompt response.

Nothing was displayed MATLAB command window. I don't know how to use the GUI. Do I need any special operations?

Is it okay to have a conversation in Japanese here? If possible, would you answer in Japanese?

Thanks for trying the workshop content. As we discussed offline, the main problem here was that the ROS node for the camera was not working correctly. Now the MATLAB based interface is working by downgrading the jetson-inference to 8498115a4ed8967c7e23f5ae27b5aa2fa1d1431b.
