Environmental Considerations
l
In case of fire, use a type D extinguisher: foam, dry chemical, or CO₂.
l
IP rating for the power supply box is IP20.
l
IP rating for the docking target is IP20.
NOTE: The IPrating for the copper charging pads is IP10. Do not expose
them to liquid.
Autonomous Charging
During normal, autonomous operation, the AMR charges its battery autonomously through the
automated charging station. The AMR knows the approximate location of the docking target
based on the map loaded onto the platform.
When the AMR arrives near the docking target, it looks for the trapezoidal shape of the dock-
ing target and drives frontward into the docking target to charge. When the AMR docks, it
mates with the charging paddle, as displayed in Figure 7-8. After the docking target verifies
that the AMR is present, and performs a series of checks. Then, it turns the power supply on
and starts charging the AMR's battery. There is about a 10-second delay between when an
AMR docks and the charging LED (yellow light), located on the power supply box, comes on.
For information on the power supply box LED indicators, see: Indicators, Controls, and Con-
nections on page 189
Connecting and disconnecting the AMR with network and onboard clients will not disturb the
charging state. However, if you move the AMR while charging its battery, the charging state
will be disturbed. The station supplies ample power for all onboard systems while charging its
battery, so you can continue operating those systems while charging.
