In my project, I am able to obtain a special pose (a future pose based on prediction) of a robot, and I need to publish the pose as tf from In the amcl_node.cpp file, it contains the following lines: I tried to use this snippet to help build my tf broadcaster, but it gives the error: My only major modification is the time stamp, because my node does not subscribe a laser scan (I also tried to subscribe a laser scan, and use the timestamp, but it doesn't work as well): I've also tried Questions:
