How much does the /odom frame matter for hector_slam?
From the hector slam tutorial, it is possible to replace gmapping with hector_slam, with or without the presence of the odom frame. What is the difference?
For gmapping, the odometry is used when there are no feature matches. What about hector_slam? What happens in an open space with sparse features, or if we are using short range laser that cannot "see" anything within range?
On the other hand, if odometry is not well calibrated, gmapping will have problems. How does this affect hector_slam if I use the odom frame?
