Re: Wall followers
Well, I wanted a sprint maze competition for year-on-year resuls, but my
intention was that we will keep running the main wall follower competition
in the full maze too, so no loss of surprise element.
I should just re-iterate that the main reasons both Duncan and I are keen
on wall followers is that (i) they are easier to build than high-speed
white line followers and (ii) there are at least four radically different
ways of attacking the problem which might allow some schools to have a bit
of internal variation too: I recall that one school at Manchester
(Ampleforth?) had a large set of very similar mice.
