2.4 Safety awareness
Personnel present in a facility with OTTO Motors products need to be made aware or be accompanied by
personnel who are familiar with the specific risks and hazards associated with automated mobile
robots (AMR).
The following checklist identifies basic topics that should be addressed by site-specific worker and visitor
safety orientation training.
Additional items may need to be addressed based on the site-specific risk assessment.
Proper PPE must be worn, including safety footwear (ie. steel toe).
Crossing into the path of a moving OTTO AMR should be avoided, as well as placing or throwing
obstacles into the path of a moving OTTO AMR.
WARNING!
Failure to follow these instructions may result in SERIOUS INJURY, INCLUDING
DEATH.
IMPACT HAZARD! Always maintain a safe distance from a robot in operation. Be
aware of the Emergency Stop button locations. For button location information, refer
to the Component Overview section of the robot OMM.
•Be aware that an OTTO AMR can be anywhere in the operating area of the facility at any time, and
may pose a tripping hazard even when not in motion.
•Personnel need to be aware of operation limitations, such as floor grades, negative and
overhanging obstacles, and the OTTO AMR LiDAR obstacle detection plane.
•The floor of the operating area should be kept free of dirt and debris.
•Personnel need to be aware of OTTO AMR docking and charging areas, where detection fields are
reduced.
See the safety information in the operation and maintenance manual for the applicable OTTO
AMR.
•Personnel should be aware of facility areas where OTTO AMRs travel through narrow
aisles/corridors resulting in reduced clearance between OTTO AMRs and personnel and
aisles/corridors shared between OTTO AMRs, other robots, and personnel.

•Personnel should be aware that OTTO AMR LiDAR safety scanners are later products rated class
1/1M. Personnel must not look directly at the laser beam source.
•Personnel should keep all loose clothing and body parts away from OTTO AMRs, accessories,
attachments, and payloads, while they are in autonomous operation. Using an Emergency Stop
button is the only acceptable manner of interacting with an OTTO AMR or attachment while it is
being operated autonomously.
In addition to the preceding basic items for all workers and visitors, the following should be considered for
facility personnel, including drivers of other robots:
High traffic areas, tight clearance areas, emergency exits, areas around electrical panels or in front
of shelves and racking, and obstacles that are outside the field of view of safety sensors (i.e.
overhanging obstacles) should have bollards placed around them so that OTTO AMRs do not drive
or stop in those areas
When required to move a product manually, personnel must ensure it is in an Emergency Stop state
(in the case of an OTTO AMR) or shut down completely and should not push manually for
prolonged periods.
See the Basic Usage section of the operations and maintenance manual for the applicable
product.
Operators of other industrial robots must not leave skids or other loads overhanging or unstable
near the edges of racking as they may not be detected by an OTTO AMR.

from all directions and visible to the LiDAR.
OTTO AMRs, attachments, and accessories are designed to work on flat and clean surfaces. Facility
conditions greatly affect their ability to operate safely and navigate properly.
2.5.1 General
•OTTO AMRs 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.
2.5.2 Driving surface
•To better assist OTTO AMRs 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
casters 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 Fleet Manager cannot be solely relied upon to prevent entry to areas with floors
that don't meet OTTO AMR requirements.
•OTTO AMRs 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 - for example, at the top of stairs,
the top of dock doors, or mezzanines without a protective ledge. Areas matching these descriptions
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.
•OTTO AMR 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 will begin to roll and may
present a hazard.
2.5.3 Environment
For additional information on the operating environment conditions, refer to the System Specifications in
the product OMM.

•OTTO AMR's use LiDAR with a wavelength of 905 nanometers, and are designed to operate
indoors free of direct sunlight. Infrared light sources (including sunlight, light curtains, welding) may
interfere with the operation of OTTO AMRs when shone directly into the robot's optical sensors.
•OTTO AMRs rely on LiDAR to protect personnel from crushing or collision hazards. Although rare,
very reflective or very light absorbent (eg. black) material can impede the LiDAR safety systems.
Avoid the use of such materials in clothing or obstacles to assist their detection by OTTO AMR
LiDAR safety systems.
•OTTO AMRs have no minimum ambient brightness requirements, as they are designed to operate
in the dark.
•When the OTTO AMR detects a significant reduction in air quality, the AMR enters a safety stop.
2.6 Payload maximums
WARNING!
Failure to follow these instructions may result in SERIOUS INJURY, INCLUDING DEATH.
IMPACT HAZARD! Never bypass the drive wheels of the robot while on a sloped surface.
OTTO Motors products support a specific maximum payload and payload dimensions. OTTO AMR
maximum payloads and their dimensions change when an attachment or accessory is connected because of
the weight of the attachment/accessory itself. In the case of an attachment/accessory-equipped OTTO
AMR, payloads must not exceed the maximum payload documented on the attachment nameplate and
dimensions specified in safety configuration documentation.
For robot, attachment, and accessory payload specifications, refer to the Hardware Library.
An OTTO AMR will require a custom robot configuration in order to accommodate payloads that project
beyond the dimensions of the base OTTO AMR platform, equipped accessory, or attachment. Contact
OTTO Motors if a custom robot configuration is required.
2.6.1 OTTO 1500 AMR
For the default configuration for the OTTO 1500 AMR, payload dimensions must stay within the projected
view of the OTTO 1500 AMR body and not project over the front, rear, or sides of the robot. The OTTO
1500 platform is rated to work with a specific maximum payload - this maximum payload changes when an
attachment is connected to the robot because of the weight of the attachment itself. In this case, the OTTO
1500 AMR should only be loaded with the maximum payload documented on the attachment nameplate.
Failure to load the OTTO 1500 AMR within the payload specifications will affect the safe operation of the
robot.

2.7 Battery handling
WARNING!
Failure to follow these instructions may result in SERIOUS INJURY, INCLUDING DEATH.
FIRE HAZARD! If the battery is damaged or a battery fire occurs, contact local emergency
services and vacate the area. Do not use water to douse the fire.
SHOCK HAZARD! Improper use or maintenance of robot batteries may result in a high energy
discharge.
Like most applications using batteries, special precautions should be taken to handle this type of material.
Battery packs should only be handled by trained personnel to ensure proper handling. Be aware of the
operating environments for OTTO AMRs and more specifically, the battery pack.
2.8 Charging the robots
For instructions on connecting the robot to a charger, refer to the Charging section of the robot operation
manual.
For instructions on connecting the charger to a power supply, refer to the Installation section of the charger
operation manual.
2.9 Overhang and underhang detection
WARNING!
Failure to follow these instructions may result in SERIOUS INJURY, INCLUDING DEATH.
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 robot OMM.
IMPACT HAZARD! Do not place anything on the robot that extends beyond its footprint. Refer
to the robot Safety Configuration document for the footprint dimensions.
OTTO AMRs use LiDAR to detect potential obstacles and obstacles located above an OTTO AMR's LiDAR
detection plane may not be perceived by an OTTO AMR. Existing equipment in your facility could be
rendered invisible to an OTTO AMR due to an "overhang", for example a robot with wheels offset from the
body of the robot itself. In the example, the OTTO AMR would detect the existing equipment's wheels but
not its body panels, increasing the possibility of a collision.
