Facility conditions
WARNING
• IMPACT HAZARD! Never bypass the drive wheels of the AMR while on a sloped
surface.
• CRUSH or IMPACT HAZARD! Keep low profile objects that the LiDAR cannot detect,
such as forklift tines and pallets, outside of the robot's path. For sensor layouts, refer
to the Component Overview section of the AMR operation and maintenance manual.
• CRUSH or IMPACT HAZARD! AMRs must be prevented from traveling in areas that do
not follow Facility Conditions specifications, such as ramps and stairwells.
• CRUSH or IMPACT HAZARD! All stairwells or similarly open holes must be marked
and surrounded by obstacles exceeding 20 cm in height with spacing no greater than
30 cm. These obstacles must be able to withstand 2000 N of force without failing or
be at least 70 mm wide from all directions and visible to the LiDAR.
Robots, attachments, and accessories are designed to work on flat, clean surfaces. Facility conditions
greatly affect their ability to operate safely and navigate properly.
• Robots should never be operated in spaces insufficient to their physical dimensions and safety
configuration specifications.
• Areas in front of or behind chargers or other docking area, for example P&D stands, must be marked
for personnel to avoid the space.
Driving surface
• To better assist robots in achieving safe stopping distances, facility floors must be dry and clean with
a coefficient of friction greater than 0.8. Debris on the floors may become caught in the wheels and
lead to premature failure of wheels, casters, or drive components. Areas with floors that can't meet
these requirements should be isolated by bollards or physical LiDAR-height barriers. Exclusion zones
in OTTO Fleet Manager cannot be solely relied upon to prevent entry to areas with floors that don't
meet the robot requirements.
• Robots should never be driven onto curbs or across gaps in the floor that may result in damage to
the robot drive systems, attachments, or accessories—or example, at the top of stairs, the top of dock
doors, or mezzanines without a protective ledge. Refer to system specifications for floor clearance
details.
• Robot drive wheels and cart brakes should never be manually bypassed on a ramp condition as this
may lead to robots or carts navigating erratically and losing control. If stopped on a slope greater than
that specified in system specifications, robots and carts may begin to roll and present a hazard.
Environment
For additional information on the operating environment conditions, refer to the System Specifications in
the product operation and maintenance manual.
• OTTO robots use LiDAR for perceiving the environment and are designed to operate indoors free of
direct sunlight. Infrared light sources (including sunlight, light curtains, welding) may interfere with the
operation of robots when shone directly into the robot's optical sensors.
• Robots rely on LiDAR to protect personnel from crushing or collision hazards. Although rare, very
reflective or very light absorbent (for example, black) material can impede the LiDAR safety systems.
