Hi , I am doing an experiment about hector slam navigation.

for the picture as below,the small tf mark is where it start and the big one is the last place .

here is my launch file (click me to github)

But the system crash when the laser scanner move every time about 10 seconds.

And shows Costmap2DROS transform timeout and can't get robot pose.

(update stauts 2016.02.27)

I guess this warning is because of the setting I modify.

I modify "hector_navigation/hector_exploration_node/config/costmap.yaml",change " transform_tolerance: 2 " to " transform_tolerance: 10".

How could I solve it? Thanks for anyone response.><

Here are the error message.

1000, plan_in_unknown: 1, use_inflated_obstacle: 1, p_goal_angle_penalty_:50 , min_frontier_size: 5, p_dist_for_goal_reached_: 0.250000, same_frontier: 0.250000

tolerance: 10.0000

Your tolerance for transforms is set to 10.000 meaning that the system will not use transform information that is more than 10 seconds old.Your system is not getting any new TF messages after 168.19 . Read about tf and do the tutorials - , then update with more info

I make some test yesterday. I guess that SLAM system crash is not because of this warning. Maybe the system sway too much make it crash.But if I want to resolve this warning,should I study more about tf ?

There is a related question (duplicate?) here, will post same answer in both.

In our case it was a performance issue, the computer was not strong enough to manage the load. I changed rviz configuration to prevent pointcloud visualisation, laserscanner vis, and furthermore I was having a process consuming 100% CPU (a node which was not sleeping while spinning). After those fixes, now everything is back to normal.

Sometimes gazebo is running at faster than real time if we wish. Real time factor > 1. In this case, we need to change the map publishing freuquency to a higher number in the navigation stack configuration files.

The problem may be with time synchronization between the machines you are using. See if time on both machines match.
