Scan matching failed, using odometry
Whenever I'm trying to navigate while using gmapping with my turtlebot2, I get the error "scan matching failed, using odometry" and as a result my local and global costmaps do not get published. In fact, the map and odom topics never get published to the move_base local and global costmaps and as a result the robot relies on odometry for navigation which is really inaccurate.
Thinking this was a problem with my parameters, I tried gmapping on gazebo on a separate pc and got the same error. Still convinced that I messed with the parameters somehow, I completely reinstalled ros and tried the gazebo gmapping tutorial found here but got the same error.
Is anyone else experiencing this issue? On my rqt_graph when using gazebo gmapping, the move_base node doesn't show up at all.
