Rev-B) and Acceleration, Deceleration, and Rotation Limits on page 74 (LD-250
Platform User's Guide, Rev-B).
• Rotational speed becomes more significant when the payload's center of gravity is
increasingly offset from the AMR's center of gravity.
• At speeds of less than 225 mm/sec, the safety laser is not active. There is a risk of
injury or property damage.
• Do not disconnect the drive motor encoder cables unless required to do so as part of
a maintenance procedure. See Maintenance on page 141 (LD-250 Platform User's
Guide, Rev-B).
• Do not drop the AMR, run it off a ledge, or otherwise operate it irresponsibly.
• Do not allow the AMR to drive through an opening that has an automatic gate or
door unless the door and AMR are configured correctly with the Call Box or Door Box
option. Refer to the LD Platform Peripherals User's Guide for details on the Call Box
or Door Box.
• Do not expose the AMR to rain or moisture.
• Do not continue to run the AMR if hair, yarn, string, or any other items have become
wound around its axles, casters, or wheels.
• Do not use unauthorized parts to repair the AMR.
• Do not power on the AMR without its wireless antennas in place.
• Although the lasers used are Class 1 (eye-safe), OMRON recommends that you not
look into the laser light.
• Sunlight and reflective surfaces can affect the AMR's laser operation.
• Do not operate the AMR in a flammable gas environment.
3.4.1.1 Falling Hazards
Physical Barriers
Use physical barriers together with logical barriers (map restrictions) to prevent the AMR
from approaching any fall hazard that is within its operating area. Such hazards include:
• The edge of a loading dock or ramp.
• Entrance to downward stairs.
• Any other vertical drop that exceeds the AMR's maximum step height.
Required characteristics of physical barriers are:
• Strength—The barrier must be attached to a solid wall or floor and should be strong
enough to stop a fully-laden AMR traveling at maximum speed.
• Continuity—The barrier must extend around the hazard completely.
