Falling Hazards
!
WARNING:
PERSONAL INJURY OR PROPERTY DAMAGE RISK
The AMR can cause serious injury to personnel or damage to itself or other
equipment if it drives off of a ledge, such as a loading dock, or down stairs.
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:
l
The edge of a loading dock or ramp.
l
Entrance to downward stairs.
l
Any other vertical drop that exceeds the AMR's maximum step height.
Required characteristics of physical barriers are:
l
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.
l
Continuity
—The barrier must extend around the hazard completely.
l
Visibility
—Mark all physical barriers to make sure that the AMR's safety lasers can
detect them easily. Barriers must extend above and below the laser's sensing plane, par-
ticularly if the floor is not flat.
Logical Barriers
In addition to physical barriers, use MobilePlanner to create forbidden areas or lines on the
workspace map to prevent AMRs from closely approaching a fall hazard. These restrictions
must be continuous so that the AMR cannot plan a path around the logical barrier.
The map features mentioned in the preceding paragraph are not interlocked methods of pre-
venting an AMR from entering a specific zone. These map features assume proper AMR loc-
alization, and therefore, if the AMR is not able to properly localize its current position it may
enter the forbidden zones. You must always install physical barriers where there is a risk of
property damage or safety hazard.
You can also use the configuration parameters
FrontPaddingAtSlowSpeed
and
FrontPad-
dingAtFastSpeed
to increase the AMR's safety clearances. This causes the AMR to decelerate as
it approaches a hazard. See:
