I changed from oneric/electric to precise/fuerte and I am using a
hokuyo laserscanner and a pan-tilt unit to generate via the
laser_scan_assembler a 3D pointcloud of the scene.
It has worked fine under oneric/electric. However since I changed to
precise/fuerte the assembled pointcloud generation does not work
The hokuyo node still publishes single laser scans without a problem.
The begin and end timings of the tilting sequences are sent to the
laser_scan_assembler node to generate the assembled point cloud. But
as a result the laser_scan_assembler node returns an empty point cloud.
After some investigation I found out under rxconsole this message from
the hokuyo node:
msg: Cached parameter is invalid for key [/hokuyo/diagnostic_period]
Does anybody knows why "Cached parameter is invalid for key
[/hokuyo/diagnostic_period]" -- I guess that causes the error.
Thanks a lot for any help.
