2.3 User's Responsibilities Falling Hazards ! WARNING: 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 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 safety navigation laser will see the barrier, and stop before reaching it. The AMR is designed to detect objects 190 mm tall, 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 that 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. Electrical Hazards WARNING: ELECTROCUTION RISK: The charging dock has AC power inside. Its covers are not interlocked.
l Do not use power extension cords with the charging dock unless properly rated. l Never access the interior of the platform with the charger attached. l Immediately disconnect the battery pack when removing the access cover. Avoid shorting the battery terminals. l Do not use any charging dock not supplied by Omron Robotics and Safety Tech- nologies, Inc. l If any liquid is spilled on the AMR, power off the AMR, clean up all possible liquid, and allow the AMR to air dry thoroughly before restoring power. 14 Mobile Robot LD Safety Guide 18393-000 Rev H
