Recharging Robot Battery

In the attic I found my son's old electric toothbrush set. He had
refused to use it as a child, and it got shelved. So what?
Well I was looking to modify the brushes so I could use them to clean
electronic circuit boards. I looked at the charging mechanism and found
it to be quite clever.
The handle of the motor/battery module is hollow. It fits into a well
that has an iron stub coming up which fits into a well in the bottom of
the hand held assembly. The battery in the module is charged by a loose
transformer coupling. The primary is in the base and the secondary is in
the hand held module.
This could be applied, if it already hasn't been, to a neat charger that
requires no bare wire connection between the charger and the robot. I
can envision a system where the robot, when it feels the need for a
charge, would naviagate to the charger and engage it by sliding over the
extended metal tranformer core. Almost pornographic!
Seems simple enough, in theory, that is.
Any thoughts?

You can certainly get plenty of power through this type of interface. The EV-1 electric car uses it.

If you continue working on this, please keep us informed. I think it's a great idea for safety and convenience.
