Hi,
I'm trying to run the gmapping package, following the tutorial here:
http://www.ros.org/wiki/slam_gmapping/Tutorials/MappingFromLoggedData
.
I'm getting errors at a few points along the way, however -- when I
try to record my own bagfile from my Pioneer 2 (which I am
teleoperating using a joystick), I repeatedly get this error:
"[FATAL] [WallTime: 1279638142.894919030]: rosrecord::Record: could
not write to file. Check permissions and diskspace" My diskspace is
definitely enough -- what permissions is it alluding to?
I then tried just using the bagfile linked to in the tutorial, but
gmapping outputs the following, repeatedly: "[ WARN] [WallTime:
1279638187.366396181]: TF_OLD_DATA ignoring data from the past for
frame /base_link at time 126.2 according to authority
/play_1279638095646529424". Using rosbag play to play the bagfile
appears to be working, but it shows this:
"RUNNING] Bag Time: 35.500164 Duration: 0.900164 /
1239670987.745222 " <-- it's counting by 1/10, so that looks too
big... it would take a while to count to that!
Thanks,
Rishi
