Chapter 8: Operation
l
Cleanliness and ESD grounding
A foreign object such as a screw or metal fragment embedded in a wheel can affect its
operation over otherwise compliant floor surfaces. Liquid, dirt, and dust can affect AMR
operation and cause damage to the AMR over time. It might also affect the operation of
the casters.
!
CAUTION:
PROPERTY DAMAGE RISK. The AMR is intended for smooth,
hard, and level floors. Although it is capable of driving over steps and gaps,
frequent or high-speed driving over such obstacles shortens the lifespan of
drive train components.
For best performance, OMRON recommends that all floor steps or door thresholds have a roun-
ded profile or are filled to ease the transition between surface planes.
The following limits apply for certain floor characteristics.
Characteristic
Operating Limits
Inclines and load
Incline (ramp) of 3% for maximum payloads.
Be aware that if the AMR frequently operates on steep
inclines its operational duration is reduced.
Step or door threshold height
Up to 10 mm at 600 mm/s.
Gap width
Up to 15 mm at 1200 mm/s
Platform Getting Stuck
It is possible, though not likely, for the platform to get into a position from which it cannot
move without Operator assistance.
Some examples are shown in the following figure.
If the platform has to be lifted to be free to drive again, refer to Safety Measures Prior and After
Maintenance on page 148.
