Yeah, that's true, of course ;-)  The "bumper car rink" idea was primarily
posited for entertainment value...

In your proposal, given the realities of contemporary battery chemistry, it
would spend a lot longer plugged in than rambling around, but I guess that
would just be its own peculiar cycle of life.... It would have to learn to
read its own battery-power monitors too.  Then it would have the
psychological decision to make, at each point in time while plugged in, of
whether to leave the wall socket to amuse itself before it's fully charged,
or stand there bored and wait till it's fully charged....  And the
introduction of new, longer-life batteries would completely change its
psychology!!

What would be better would be if its grabber arm and fingers were good
enough to enable it to swap a series of batteries in and out.  Of course,
actuators of this quality exist and are in use in industrial robots, but
they don't appear to be available for this inexpensive bot.
