7.6 Sensors
Lasers
The LD-250 uses an on-board laser for navigation and safety. A second low front laser detects
obstacles that are too close to the ground for the main laser to detect. An optional rear-facing
laser is also available. See: Rear-Facing Laser on page 188.

Safety Scanning Laser
The LD-250 Safety Scanning Laser [(A) in Figure 7-8] is an Omron OS32C model. It is a precise
scanning and navigation sensor with the following characteristics:
l Single horizontal plane, parallel to the floor at a height of 190 mm (7.48 inches).
l 601 beam readings in a 240° field of view (0.4 degrees per beam).
l Maximum safety protection range of 3 m (9.8 ft).
l Typical distance for range readings of 15 m (49 feet).
Constraints on Laser Operation
The laser cannot reliably detect glass, mirrors, and other highly-reflective objects. Use caution
when operating the LD-250 in areas that contain such objects.
