4.2.1 Rear Sensor Operational Considerations
The figure below is a top-down view of the LD-250 showing the approximate locations of the
sensor fields (not to scale). As the figure below shows, there are sensor blind spots to the
left and right of the AMR.
Figure 5: Sensor fields of view (approximate)
It is unlikely that an AMR can drive into a person because of these sensor blind spots, and
when path planning, the AMR never drives autonomously in a reverse direction. However,
under certain circumstances, the AMR can be commanded to move in a reverse direction
and it is possible that a person or object might move into the sensor blind spot without
being detected by the AMR.
The AMR is operating at a low speed (225 mm/sec) during such maneuver, but an AMR with
its payload has considerable mass, and might tip a person over. If your AMRs operate in the
same workspace as people, provide information and training for people so that they:
