Hello,

I'm driving Husky A200 by using a joystick with this command:

roslaunch clearpath_teleop example.launch

everything works OK, but I would like to print in the shell and also write in a text file the current used by the motors, the temperature and in particular the linear and angular velocity.

I know that clearpath_teleop cmd_vel publishes some information, but how can I read them and save them in a text file?

rosbag can be used to save data that is published. There is logging for C++ & Python. I don't believe that the Husky publishes motor current and temperature.

@tony is correct that rosbag is the best way to do it. Use "rostopic list" and "rostopic echo" ahead of time to look at the available topics. The Husky does make data available in other topics, including motor temperature, current, and voltages.

Hi,

I have no experience with Husky but generally Ros robot publishes all of the information as Ros Topic / Service. So i will suggest to go through the basic Ros tutorials here and see how these works.
