Considerations - Omron LD-250 Assembly Instructions Manual

• Provision for an auxiliary warning light on the LD-250 Core (the Light Pole connector,
described in LD-250 Core Rear Upper Connectors on page 100 (LD-250 Platform User's
Guide, Rev-B). You can use this connector to mount a warning light in a more
prominent location, which might be appropriate for AMRs that have taller payloads.
5.1.3 Warning Buzzer
The LD-250 Core provides an output for controlling a warning buzzer as an auditory warning
device. The default behavior of the buzzer is to sound when the AMR is moving in reverse,
or when its safety systems are off.
You can configure the buzzer's operation. For example, you can set it to make a warning
noise whenever the AMR is moving.

Considerations

5.2.1 Performance
Performance factors to consider when designing a payload structure are:
• Size, weight, and center of gravity of the payload structure.
• Power requirements for any electrical devices on the payload.
• Serviceability and maintenance requirements.
Adding weight to the LD-250 tends to have less effect on battery run time than does
increasing electrical power consumption.
Operating your AMR over soft surfaces (such as carpet) significantly shortens battery
runtime than compared to hard surfaces.
5.2.2 Weight Constraints
The total operating weight of the AMR should comply with its specifications for payload and
any objects carried.
When designing and implementing your payload, consider the following items. You may
need to adjust your emergency deceleration values in order to prevent tipping. Note that
lowering emergency deceleration values will affect the AMR's stopping distance, which may
require that the safety scanning laser's protection fields are increased in size to account for
this additional distance.
