How to publish/subscribe when a specific event occurs
Hello everyone. I'm a ROS beginner.
I would like to publish/subscribe a ROS Topic when a specific event occurs
For example,
when -20 < angle < 20, I want to publish motor speed msg.
Is there any good way?
The question does not have enough details. Where all in your code is
angleupdated? Every timeangleis updated, the "obvious way" is to check for that condition and if true publish. However, without more info, it's difficult to see why the "obvious way" might not work.
