Matlab ROS : rosbag record from Matlab computer on Turtlebot

It is possible to execute the command line to record a rosbag from Matlab to the turtlebot. . I try with

if true
  % code
  rosdevice('MyIP','Username','Password')
  system(d,'rosbag record --duration=10 -o NameFile /odom')
end

but I have an error: STDERR : bash : rosbag: command not found . I'm able to do this with the command -> openShell(d). And type in shell directly : rosbag record --duration=10 -o NameFile /odom. After upload on my Matlab coomputer : getfile(d,'path/name');

But if it is possible to do all this directly in Matlab without 'openShell', that will be great ! Thank you in advance for your help

Hi Vincent,

Have you assigned the rosdevice object to d ?

I don't see it in your code.

Try this:

    d = rosdevice('MyIP','Username','Password')
    system(d,'rosbag record --duration=10 -o NameFile /odom')

This will execute any system command on your rosdevice which is supported. Please check if you have set the ROS environment variables properly.

Hi, Yes I well assigned rosdevice. Yesterday evening I find the issue... it is my ssh install that failed on my Intel UP board… I re-install all… and now all works. Thank you for your time I should close the question

Make sure your ssh works perfectly on the intel up board before try to upload Matlab code on it
