Fatal error while trying to build map from logged data. (hector SLAM)
I've been following this tutorial, http://wiki.ros.org/hector_slam/Tutor... , but I never got past step 4. My OS version - Ubuntu 14.04 and I'm running ROS Indigo.
I get the following error:
Patrick@grimreaper:~$ rosbag play Team_Hector_MappingBox_RoboCup_2011_Rescue_Arena.bag --clock
