Hey, I was trying to make an action server which would calculate the distance of the robot from its initial position for 20 seconds. In the feedback, it shall display distance travelled after every second and after 20 seconds in the result, it will show all the odometry points recorded (x, y) coordinates. (The problem is not related to the first ROS project, I made it on my own to practice).
I am not moving the robot or anything, was just trying to see if my server works fine. It is generating the desired feedback however, after 20 seconds, instead of providing result, it generates an error shown below:
My action server is:
I initially tried by publishing to the goal topic and then echoing from the result and feedback topic. Then I made a client, but I’m getting the same error.
I think its saying that the state is in WARN condition, but I don’t know what it means and what to do about it. Even the previous error, I’m not too sure about that. Could anyone help me with this?
Thank you.
