Cant deploy ROS on raspberry Pi4 with Simulink ?

Hi,

I am trying to use deploy the example ''getting started with Robot operating system (ROS) on raspberry'' but I get error (see pictures) that I cant resolve.

My ROS, is installed on win10.

My Raspberry Pi 4 got the latest version image from Matlab.

Can someoe help ?

Best regards,

Hi Hocine YAKOUBI,

The error that you see in the build "Cannot identify a ROS distrubution in /opt/ros" can be worked around by executing the below commands on the pi terminal,

echo "MW_ROSDISTRO=melodic" |sudo tee -a /etc/environment

Bascially, we need to tell Simulink the version of ROS present on pi. This is currently done via setting a specific environment variable in /etc/environment file. I am guessing the environment file may be corrupted. You can check the contents of it by executing "cat /etc/environment". By running tha above cmd, we are appending the needed environment variable to the file.

Please let me know if this works.

Thanks,

Prasanth
