This software driver implements the protocol SCIP-2.0 for interfacing HOKUYO URG, UTM and UXM laser scanners.
Refer to the wiki page for more details: http://www.mrpt.org/Example:HOKUYO_URG/UTM_Laser_Scanner
See also the application "rawlog-grabber" for a ready-to-use application to gather data from the scanner.
