2.2 Safety Awareness
Personnel present in an OTTO Motors facility 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.
Caution
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.
Impact
Never move quickly into the path of a moving robot. Robot LiDAR safeguards offer
protection against static or slow moving objects within its detection range but will be
unable to safeguard against personnel running or jumping into its path.
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 Product Safety section of the operations 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 vehicles, and personnel.

be duplicated, reproduced or further disclosed without the express written approval of Clearpath Robotics Inc.
See the Product Safety section of the operations and maintenance manual for the applicable
OTTO AMR.
Personnel should be aware that OTTO AMR LiDAR safety scanners use a class 1 laser and high
intensity LED.
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 vehicles:
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 vehicles 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.
Alert personnel that while operating an OTTO AMR outside of the Autonomy State, they are solely
responsible for obstacle and collision avoidance.
Maintenance not outlined in the operations and maintenance manual can only be performed by
OTTO Motors Authorized Personnel.

2.3 Facility Conditions
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.
Warning
Bypassing the drive wheels of an OTTO AMR while it is on a ramp is a dangerous situation
where the OTTO AMR may move unexpectedly. Never bypass drive wheels unless the OTTO
AMR is on a flat surface that is clear of objects.
•Facility floors must be dry and clean with a coefficient of friction greater than 0.4 to better assist
OTTO AMRs in achieving safe stopping distances. 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 vehicle 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
should be isolated by bollards or physical LiDAR-height barriers.
Crush
LiDAR safeguards offer protection from collision and crushing by OTTO AMRs to
nearby pedestrians within the LiDAR detection plane. Objects such as forklift tines, or
low-profile pallets outside of the detection plane are not safeguarded against by the
LiDAR system and can be struck by an OTTO AMR. Secondary injuries such as collision
or crushing resulting from an object being pushed by an OTTO AMR are possible.
•OTTO AMRs 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 vehicle'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.

or trade names of their respective companies. The information contained in these documents is the Confidential and/or Proprietary property of Clearpath Robotics Inc. and may not
be duplicated, reproduced or further disclosed without the express written approval of Clearpath Robotics Inc.
•Areas in front of or behind chargers or other docking areas (eg. P&D stands) should be marked for
personnel to avoid the space.
•OTTO AMR drive wheels and cart brakes should never be manually bypassed on a ramp condition
as this may lead to vehicles or carts navigating erratically and losing control. If stopped on a slope
greater than 1° (1.6 % grade), vehicles and carts will begin to roll and may present a hazard.
Warning
Ramps with a slope of greater than 3° (5 % grade) must be identified and blocked from
all OTTO AMR traffic.
2.4 Payload Maximums
OTTO Motors products support a specific maximum payload. OTTO AMR maximum payloads 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 should not exceed the maximum
payload documented on the Attachment Nameplate.
Caution
Loading an OTTO Motors product with more weight than specified by the attachment,
accessory, or base OTTO AMR (when no attachment is present) will prevent OTTO AMRs from
correctly determining stopping distances and may also damage the vehicle, attachment, or
accessory. Never load an OTTO Motors product with more weight than is specified by the
current signage on each OTTO AMR and accompanying attachment or accessory.
2.4.1 OTTO 1500 AMR
The OTTO 1500 platform is rated to work with a maximum payload of 1500 kg - 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.

be duplicated, reproduced or further disclosed without the express written approval of Clearpath Robotics Inc.
2.5 Battery Handling
Like most applications using batteries with Lithium technology, 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.
Warning
Whenever completing inspections or maintenance on or around the areas of an OTTO AMR
battery pack, follow the proper Lock-Out Tag-Out Procedure for the applicable vehicle. Not
properly following the Lock-Out Tag-Out procedure can result in live voltage locations on the
OTTO AMR. Always be sure to lock-out the vehicle before proceeding with inspections and
maintenance.
2.6 Overhang and Underhang Detection
Existing equipment in your facility could be rendered invisible to an OTTO AMR due to configuration of an
"overhang" - for example, a vehicle with wheels offset from the body of the vehicle itself. 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. In this example, the OTTO AMR would detect the existing
equipment's wheels but not its body panels, increasing the possibility of a collision.
We encourage installation of perception-assist flaps (see the following) to assist OTTO AMRs without 3D
perception capabilities in detecting obstacles - especially in cases of potential mobile obstacles.
Figure 1 Perception-Assist Flap Installation
OTTO AMRs capable of 3D perception - either integrated or through use of an equipped 3D Perception
Attachment - are better able to detect overhanging obstacles without the presence of perception-assist
flaps.

•Ideally, installed flaps should touch the floor; however, in instances where the flap can't be installed
that close to the floor, the distance between the flap's bottom edge and the floor should not
exceed 75 mm.
•Opaque materials with a matte finish are best as reflective materials can scatter LiDAR
pulses. Rubber works especially well due to its flexibility, color, and durability.
•Flaps can be bolted directly to exterior body panels or secured using high-strength magnets.
Caution
Failing to take LiDAR detection field dimensions into account will increase the possibility of a
collision. See the operating manual for the applicable OTTO AMR.
