Maybe this is a quibble, but aren't the parents of most "kids" likely to be using Mindstorms in the 35+ age group???

(...) The problem is that servo's are driven by signals that are considerably narrower than the 1/100th second resolution timers that the Lego firmware provides. They use pulse-width modulation - so the width of the pulse determines the position of (...) (25 years ago, 1-Feb-01, to lugnet.robotics)

Can you "drive" a Lego train with an RCX? The Lego 5300 has a power connector on top, or perhaps just power the rails? (25 years ago, 1-Feb-01, to lugnet.robotics)
