Falling Hazards
DANGER: PERSONALINJURYORPROPERTYDAMAGERISK
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
The edge of a loading dock, the entrance to downward stairs, or any other substantial drop
that is within the AMR’s expected operating area should be physically marked so that the
AMR’s navigation laser will see the barrier, and stop before reaching it. The AMR is designed
to detect objects up to 200 mm in height, so the barrier must be at least that tall. However,
because of variations in floor flatness, we recommend a barrier that is 250 mm tall.
The barrier needs to be continuous at the site, so that the AMR can’t drive around or through
it to the dropoff.
Logical Barriers
You should also use forbidden areas, sectors, or lines with several feet of safety zone (padding)
before the actual dropoff, to ensure the the AMR will not try to drive there.
These need to be continuous at the site, so that the AMR can’t plan a path to drive around or
between them to the dropoff.
