Hi,
I am working on a project which scans rooms and builds the complete map of the room. The ros code that I wrote requires multiple subscribers (eg for Pose and Obstacles). I want the subscription to be sequential. However with the use of spin() or spinOnce() my program gets stuck in the first callback function. How do I solve this problem ?
What do you mean sequential?
ROS data comes from the system, whenever it is published.
If you want to match arriving data message filters might be, what you need.
Documentation of threading is at http://www.ros.org/wiki/roscpp/Overview/Callbacks%20and%20Spinning
