Re: [ros-users] ROS looses connectivity after some time

Hello Eitan,

I am running an AMCL (diff drive) in which parameters are:
<param name="odom_frame_id" value="/odom"/>
<param name="base_frame_id" value="/base_link"/>
<param name="global_frame_id" value="map"/>

In my global costmap conf:
global_costmap:
global_frame: /map
robot_base_frame: base_link

and in LocalCostMap conf:
global_frame: odom
robot_base_frame: base_link

and in odom TransformStamped message settings:
geometry_msgs::TransformStamped odom_trans;
odom_trans.header.frame_id = "odom";
odom_trans.child_frame_id = "base_link";

The link is: /map->/odom->/base_link->/base_laser_link

As i said initially it works nicely but after some period it falls off.

My simulation real time parameter is set to false. If i make it true the
navigation stack hangs.
<param name="use_sim_time" value="false"/>

Please let me know if i need to sync. frequency.
