Laser Navigation Package
The Laser Mapping and Navigation accessory package for MobileRobots research platforms provides a SICK laser rangefinder fully integrated with the robot platform and onboard computer (power and data), and includes a suite of development software for automatically creating maps, and for accurate, autonomous intelligent localization and navigation of the robot. Laser navigation can be used in most indoor spaces, and also in outdoor spaces on level ground if enough buildings and stationary obstacles surround the operating environment.
- SICK LMS-100/111 or LMS-500 laser rangefinder (please specify when inquiring)
- Mounting hardware for the robot base platform, assembled
- All cabling, power supply, etc., assembled
- Mapper3 map making software
- ARNL intelligent localization and navigation development libraries
- MobileEyes remote GUI application
- All hardware assembled, installed and tested on your robot
- All software installed on onboard computer. Help, documentation and lifetime upgrades.
- Robot is ready to begin mapping and demonstrating navigation capabilities immediately out of the box
- Robot base platform (any robot except Amigobot)
- The optional integrated gyroscope correction system for the robot base is recommended for greater accuracy
- Onboard computer
- The laser navigation system may be used to autonomously drive some robots into automatic recharging stations.
- For outdoor robots equipped with GPS, the laser navigation software may be used in the same program as the MOGS outdoor navigation system.
MobileRobots' industrial and commercial systems rely on the same laser mapping and navigation algorithms and techniques as implemented in the Laser Navigation Package to provide highly reliable delivery and manufacturing systems to customers around the world.
Quick laser mapping
Mapping a location is simple. Just teleoperate the robot around the environment to be mapped while laser data is captured. Then load the data into Mapper3 and watch as walls, doors and furniture appear. Are there people walking by? No problem. Moving objects will typically disappear or may be edited out later.
Comparing laser and 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 – up to 32 m -- while sonar cannot accurately read beyond 5 m. A robot running with laser can operate for days, weeks or even months without becoming lost.
Also available for purchase is laser rangefinder hardware only with mounting bracket and power supply/integration kit.
For extra obstacle sensing and avoidance, add a small Hokuyo URG laser sensor.

SICK LMS-1xx Rangefinder Details
Now available are the SICK LMS-100 (for indoor use on Pioneer and other indoor robots) and LMS-111 (for
outdoor use on Seekur and Seekur Jr. robots) rangefinders. The LMS-1xx lasers are
smaller and lighter weight than the LMS-500 with lower power consumption, and feature an 270° field of view, but
with lower scanning frequency and bit less range and more error.
Please specify when inquiring whether you are interested in the LMS-1xx or LMS-500.
