Matlab ROS : rosbag record from Matlab computer on Turtlebot

Asked by Vincent Talon on 12 Aug 2017
Latest activity Answered by Vincent Talon on 16 Aug 2017
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.

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