Mechanically, LEGO is beautiful to work with. The components are well
selected for rapid prototyping. For example, you will find that the hole
spacing in the beams and the center-to-center distances of the gears ...seem
to work well together.
However, it is not always obvious how to make transitions between (say) a
beam and a brick. This is not trivial; you should count on doing some
guided projects out of the excellent literature available before you go off
inventing a new kind of AI floating platform. I can promise that you will
enjoy every moment of this 'homework'.
Other, more knowledgeable folks will give you a better answer on the
software side. However, the programmable brick (RCX) is a competent
computer on its own. You design a program in pbFORTH or NQC (reduced
instruction set 'C') or others and transfer it to the RCX via an IR link.
The link works well at a short distance setting or long distance setting.
The program then runs independently. There is an accessory IR remote (like
a TV remote) that lets you send 'messages' to the robot. A message might
select a task or become a variable in a task. My remote works well up to
perhaps 8 or 9 meters. There is a VCR accessory set where the images are
processed in your PC and instructions sent back to the robot ...so I suspect
you can have your PC link within limits, but I don't know enough to explain
that.
And, make sure you can actually purchas an RIS 1.5 as they are hard to find
these days.
You can see a simple example of a lego project on my web site at
http://www3.sympatico.ca/jdkalpin complete with NQC code.
I hope this helps,
Jerry
