7 Payload Structures
Everything that you attach to the LD platform is referred to as the payload structure.
In the case of the LD Cart Transporter models, Omron designs and builds the payload structure. In most
cases, you will need to design a payload structure that suits your application. This chapter discusses
considerations to be aware of when you design a payload structure for your LD platform.
The LD platform provides the mobility and navigation you will need, as well as power and I/O connections
between the platform and your payload structure, so the two can work effectively together.
7.1 Safety Warning
Warning Label
A No Riding label is shipped, unattached, with each platform. It is the user’s responsibility to place this in a
prominent location on the payload, so Operators will see it.
Warning Lights
An AMR is required for CE compliance to 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 in Rear Upper Core. This can be used to drive a warning
device in a more prominent 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, for example, when the platform is
moving at a speed lower then 300 mm/s (225 mm/s for the LD-90 and LD CT-105 models). The warning
buzzer’s behavior is configurable by the user, so it can be used to sound, for example, whenever the AMR is
moving.
A buzzer kit, with buzzer and harness, is available as an option.
7.2 Considerations
The main performance factors to consider in designing a payload structure are stability, size, weight, and
center of gravity of the payload structure, and power requirements.
