I purchased an Arduino Robot today.

I would like to know the minimum current rating of a 9-V AC-to-DC adapter
for charging the four butteries.

Any information?

Thanks and best regards

This is a self-response.

I have checked
 the circuit diagram
 and the data sheet of
    "LTC4060 Standalone Linear NiMH/NiCd Fast Battery Charger" from Linear Technology.

It seems that the charge current is programmed at about 600[mA]
(more precisely, 591[mA]).

I could use a 1.2 [A] AC-to-DC adapter in my junk box.
