I'll care what the voltage is, becuase I have to buy batteries for it/use a
wall wart. Higher voltage == more batteries/more expensive batteries, and
also more space. So, it seems to me (since the RCX/siblings are already
fairly large on a Lego scale), that the voltage can only get lower. I have
not seen the spybotics sets, so I don't know how good they are. However, by
lowering the voltage, you lose backwards compatibility with existing pieces,
assuming a connectiviy plan to hook them together. With a higher voltage, a
2x4 stud brick could lower the voltage to 9V and fix that issue.
I agree with you - the beauty of Lego is the ability to build anything you
want. With 2 motors 180º apart, fixed into position 6 studs apart, the
creative applications are limited. Perhaps then better power transfer
styles ala the flexible axles will be developed.

| (...) But the total *energy* stored per battery doesn't change - so if there are more batteries then the time between battery changes will be larger. To at least a first approximation, you'll use the same number of batteries no matter which voltage (...) (22 years ago, 2-Sep-02, to lugnet.robotics)
