9.3 Payload Structure Bumpers
9.3 Payload Structure Bumpers
The LD-250 Core provides User Bumpers connector provides 6 circuits for payload bumpers.
See: User Bumper on page 105.
IMPORTANT: The User Bumpers connector is not safety-rated and is not part of
the E-Stop chain.
9.4 Call Buttons and Door Boxes
Use optional Call buttons to send an AMR to associated goals. Even in an installations with a
single AMR, you can install multiple Call buttons.
Optional Door Boxes open powered doors so the AMR can pass through.
For more information about these options, see: LDPlatform Peripherals User's Guide.
9.5 Acuity Localization
If the workspace contains many transient obstacles, such as pallets or carts, these objects are
not recorded on the workspace map and they might block environmental features that are on
the map. Such dynamic environments can make accurate laser localization more difficult,
slowing the AMR's progress and accuracy.
Acuity Localization is an optional supplemental method of navigation. The primary safety
and navigation laser still provides data for local path planning and obstacle avoidance.
Acuity localization uses an upward-facing camera to localize the AMR. It does this by com-
paring a dynamic scan of the overhead environmental lighting with a stored image in its work-
space map. Each overhead light provides a reference point, and groups of lights provide
navigation cues. You can mount the camera on your payload structure, provided it has an
uninterrupted upward view of the environmental overhead lights.
9.6 Touchscreen
The Touchscreen is an optional full-color, touch-sensitive screen. Information such as mes-
sages and status data from the AMR appears on this screen. Use it to input operational com-
mands directly at the AMR, instead of remotely from MobilePlanner.
See the LDPlatform Peripherals User's Guide for detailed information.
9.7 Rear-Facing Laser
You can configure an additional laser either as a rear-facing laser or as a vertical laser. In the
latter case, mount the laser so that its scan plane is perpendicular to the floor plane and par-
allel to the AMR's X axis.
The laser kit consists of the following items.
