The guys at NASA *are* undoubtedly very smart at working around
problems - but that's a REALLY poor example (and I know everyone
uses it).  If you look at what they actually came up with, it
boils down to using some available plastic and cardboard to
duct-tape the square canister to a hose and the hose to the round
hole.   I don't think I can imagine *ANYONE* who'd have trouble
solving that problem.

I'll give you a much better example though.

(I'll admit here that I don't have precise details - but this
is the gist of it)

On one of the planetary science probes heading out past Jupiter
and Saturn, they had a problem with a mis-aligned sensor.  It
had been attached to a boom with some special adhesive that
is designed to retain integrity and to avoid out-gassing when
held in a vacuum.  However, the sensor was slightly mis-aligned.

They did simulation of the crystalline structure of the adhesive
in a supercomputer and figured out a heating and cooling cycle
that would soften the adhesive.  By rotating the sensor into the
sunlight and over-driving the electronics so that they started
overheating - they managed to soften the adhesive and apply a
sudden (but accurately calculated) jolt to the manouvering thrusters
to twist the spacecraft enough to apply just the right force to
realign the sensor - thereby repairing the probe.

Now *THAT* is rocket science.

Messing with duct tape and cardboard is what they teach in
Kindergarten - I want my kid to do rocket science.

(That's an analogy - he wants to do movie special effects).

All, I've been folllowing this thread with a lot of interest, and as the author of pbForth - yet another Mindstorms programming language I'd like to weigh in on this subject. You have to remember that FLL is all about engineering and tinkering. I (...) (22 years ago, 11-Mar-05, to lugnet.robotics)
