5.2 Considerations
Other warning labels are applied at the factory.
Warning Lights
To comply with CE requirements, an AMR must have a readily-visible warning device, such
as a flashing light, when it is either ready to move or is moving. The platform comes with
light discs on each side that do this. The core also provides an output, so you can add your
own warning device. This may be necessary for taller payloads, which may make the side
light discs not always visible. The core has a Light Pole connector, which is covered in LD Plat-
form Core Rear, Upper on page 87. This can be used to drive a warning device in a more prom-
inent location for taller AMRs.
Warning Buzzer
The core provides an output for driving a warning buzzer. The default behavior of the buzzer
is to sound when the AMR is moving in reverse, or when the safety systems are off. Its beha-
vior is configurable by the user, so it can be used to sound, for example, whenever the AMR is
moving.
5.2 Considerations
Performance
The main performance factors to consider in designing a payload structure are the size,
weight, and center of gravity of the payload structure, and power requirements. Adding weight
to the platform tends to have less effect on run-time than adding electrical power requirements.
Operating your AMR on carpet will have a significantly shorter run-time than on hard sur-
faces.
Weight
On a hard surface, a certain amount of extra weight will not shorten the AMR's run-time very
much. When adding a payload structure with substantial weight, the center of gravity of the
entire AMR needs to be considered. This is particularly important if you intend to equip the
platform with a robot arm, which would be lifting items off-center from the platform. A heavy
payload structure, with most of its weight concentrated just above the platform, will be much
more stable than the same weight payload structure in which the weight is either off-center or
high above the top of the platform.
NOTE: The weight of your payload structure plus the weight of the parts it is
carrying must not exceed the rated capacity of your platform.
