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.

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.

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.

•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.

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

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.

responsible for obstacle and collision avoidance.

Maintenance not outlined in the operations and maintenance manual can only be performed by

OTTO Motors Authorized Personnel.

2.5 Facility Conditions

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.

CRUSH or IMPACT HAZARD! Keep low profile objects that the LiDAR cannot detect, such as

forklift tines and pallets, outside of the outside of the robot's path.

CAUTION!

Failure to follow these instructions may result in MINOR or MODERATE INJURY or DAMAGE

to the system and/or property.

CRUSH or IMPACT HAZARD! Robots must be prevented from traveling in areas that do not

follow Facility Conditions specifications, such as ramps and stairwells.

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.

•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 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

should be isolated by bollards or physical LiDAR-height barriers.

•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 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

OTTO 750/1500 Fast C harge r V1.2 • OM M- 000001 • REV. D

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.

LiDAR safety systems.

•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 robots or carts navigating erratically and losing control. If stopped on a slope

greater than 1° (1.6 % grade), robots and carts will begin to roll and may present a hazard.

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. 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.

2.6.1 OTTO 100 AMR

For the default configuration for the OTTO 100 AMR, the payload must lie within the projected view of the

OTTO 100 AMR body and not project over the front, rear, or sides of the robot. The payload must be

smaller than 740 mm x 550 mm and no higher than 1700 mm. The Center of Mass of the payload must lie

within the constraints dictated by ICD-000079 and not exceed a mass of 150 kg.

Where the payload is carried on a Staging Cart, the payload must lie within the projected view of the

Staging Cart and be smaller than 912 mm x 803 mm and no higher than 1500 mm. It may not project

beyond the boundaries of the cart footprint. The allowable position of the Center of Mass of the payload is

dictated by ICD-000073 and must not exceed a mass of 130 kg.

The OTTO 100 AMR requires a custom vehicle configuration in order to accommodate payloads that

project beyond the dimensions of the base OTTO 100 AMR platform or Staging Cart. Please contact OTTO

Motors if a custom vehicle configuration is required.

2.6.2 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.

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 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.

2.8 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 outside of the robot's path.

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.

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.
