Laser Mapping & Navigation
System with ARNL Software

MobileRobots' Laser Mapping & Navigation system makes precise laser data available to your program through Advanced Robotics Navigation Layer (ARNL) for building your own navigation routines or automatically operating with path planning and localization. In addition, the Scan Studio Laser Mapping utillity measures and builds floor plans in minutes. These floor plans can then be edited in our Mapper utility. Includes ARNL plug-ins for developers. Also available with MobileEyes end user application software for tour guides, security patrols and other applications requiring a behavior scheduler/sequencer within a mapped location.

COMPARING LASER & SONAR NAVIGATION

Within a single plane, the precision of lasers is 25 times that of sonar (180 readings in 180 degrees vs. 8). The error rate of sonar is far higher because the sonar is emitted in a 15-degree cone and depending upon the surface ahead, sound may bounce away from the detector. Also false positives are not uncommon. Sonars' sensing cone, however, does mean that they can see objects outside the single plane sensed by a single laser. Lasers can sense objects further -- 10 or even 50 m -- while sonar cannot accurately read beyond 5 m. Hence a robot relying on sonar is lucky to operate half an hour without losing its bearings. A robot running with laser can operate for days, weeks or even months without becoming lost.

ADVANTAGES OF GYROSCOPE CORRECTION

Gyroscope Correction System adds an even greater degree of precision to Laser Mapping & Navigation. A robot with the gyroscope correction is less subject to errors caused by very uneven terrain, slippage, bumping by humans or other machines, and other interference.

Quick Laser Mapping

Mapping a location is simple. Just launch the mapping utility and tele-operate the robot around the building to be mapped. Watch as walls, doors and furniture appear. Are there people walking by? No problem. Moving objects will typically disappear or may be editted out later.

KEY FEATURES Maps a room in seconds Maps may be edited Laser measures distances up to 50 m Laser scans up to 180 degrees Laser controls integrated with ARNL Laser data accessible through ARNL Laser data integrated into path planning and localization Compatible with MobileRobots dock/charge stations!

Indoors any P-series robot can use Laser Mapping & Navigation with ARNL to map and navigate buildings.
