3 Safety
3.1 Intended Use
The LD-250 is designed to operate in indoor industrial environments. In general, if a
wheelchair user can safely and easily navigate the environment (open, and mostly flat with
only gentle inclines and wide doorways), then it is navigable by an LD-250.
The following guidelines apply:
• Floor—Clean and dry floors that you sweep regularly and routinely keep free of
debris, dust, and liquids.
• Typical Inclines—The LD-250 is intended to operate in a workspace that has a mostly
flat floor. If the workspace includes inclined areas, OMRON recommends a gentle
incline typical of wheelchair ramps. Be aware that the payload structure and any
loads transported can:
o Reduce the AMR's ability to traverse an incline.
o Change its operating center of gravity (CG).
• Inclines (Ramps)—With a properly designed and stable payload, the LD-250 can
operate on ramps at full payload capacity. However, extended periods of operation
on ramps will affect battery duration and speed is limited to 600 mm/sec on inclines
such as ramps. Operational recommendations are:
• Temperature 5 to 40°C, with a recommended humidity range of 5% to 95%, non-
condensing. Operating the LD-250 at high or low ambient temperatures (particularly
with a full payload and high speeds) can cause the battery to exceed its operating
temperature limits. If this happens, you are notified by escalating software messages
as follows:
o The battery is approaching a high or low temperature limit. Change the LD-
250's operating conditions so that the battery can return to within its
temperature limits.
