Well, Lego has some -- check out Lego Dacta. But I think those are mostly
targeted at a younger age.

REALLY like the idea of Prey & predator to split the class into

Prey and predator is _very_ difficult. It's hard for one robot to detect the
relative location of another. (If someone has a good solution for this, I'd
love to hear.)



Well, my (perhaps naive idea) was to start with some very, very simple
feedback loops of the kind: a) program a robot to find a fixed target using
only reactivity to a gradient (this approach would simulate a very
rudimentary sense of smell); b) implement a more precise sense of direction
by doubling approach (a), i.e. trying to keep the source of the stimulus
between two adequately spaced sensors; (c) implement a "follow the wall"
algorythm and combine it with (b), etc.
I used these ideas (taken from Abelson/DiSessa experiences teaching Logo to
MIT and High Students and reported in their book Turtle Geometry) many
years ago in a virtual environment and they worked quite well. I do not
know how difficult it would be to implement them "in flesh and bones" since
I have had no time to play with Mindstorms yet. Not seriously, I mean. I
expect the tasks not to be trivial, but perhaps doable? Perhaps some of the
experienced Mindstormers on the list can comment.

I teach electronics to 11th & 12th graders at a vocational school near Lake Ontario N.Y.(BOCES). I am trying to convince my boss that Mindstorms is THE thing I need to teach intro to robotics. I am getting a set for myself this weekend to learn (...) (26 years ago, 2-Dec-98, to lugnet.robotics)
