ExRobotics ExR-2 Operating Manual page 11

Sometimes there might be temporary items in the surroundings, e.g. people, cars or scaffolding.
These should be minimised as far as possible because they will be incorporated into the 3D model.
However, provided there aren't too many temporary items the robot will still be able to localise its
position using the other information in the map.
Temporary items do not affect object avoidance because this is based on live LiDAR data that is
gathered during the ongoing mission. However, it should be remembered that object avoidance
isn't perfect. The following conditions can hamper performance.
Condition Description
Drop-offs Drop-offs are more difficult to detect than
obstacles because if the ground is very
reflective (for instance in heavy rain) there
might be false positives and steep downward
ramps cannot be reliably distinguished from
drop-offs using LiDAR alone.
Upwards The robot will usually interpret these ramps
ramps as an obstacle and stop.

Potential work-arounds
Drop-offs are usually
permanent features and it's
very serious if the robot drops
from a height. Robot routes
should avoid drop-offs or
barriers should be erected
around them.
