8.1 Operating Environment
This specifically includes wires hanging from above the AMR, which could pose a
hazard if the AMR ran into them.
l large, highly-reflective objects
Environment and Floor
Environmental Limits
The following environmental limits apply.
Characteristic Operating Limits
Temperature 5 to 40°C
Humidity 5% to 95%, non-condensing
Altitude Up to 1000 m above mean sea level
Atmospheric
WARNING: Do not use the AMR in hazardous
environments (explosive gas and oil mist).
Radiation Do not use the AMR in the presence of ionizing or non-ionizing
radiation.
Floor Characteristics
Floors must provide good traction, typical of good walking conditions. The following specified
limits assume that the AMR's wheels are in good operating condition.
l
Flatness and Texture
Driving on rough or uneven floors can affect traction and navigation and also reduce
the life of drive train components. Safety might be affected because the laser's sensing
plane is not always parallel to the floor.
Even on smooth, level floors, dust, dirt, grease, and water (or other liquids) can affect
traction. If the drive wheels slip it can potentially affect operating duration and nav-
igation accuracy.
Use a slip meter (such as the Reagan Scientific BOT-3000e) to measure the floor’s coef-
ficient of friction. The slip meter must:
l
Conform to standards ANSI B101.3, A137.1, A326.3.
l
Be validated according to ASTM F2508-13.
The recommended coefficient of friction for floors in the AMR’s work space is in the
range: 0.55 – 1.0.
l
Steps and Gaps
Typical floor characteristics that are considered to be steps include any height difference
caused by floor stab settling, expansion gaps, or cracks. Other environmental objects
might create a temporary bump, such as a wood pallet fragment, dropped fasteners or a
temporary floor covering.
