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

Greetings all,

I am persuing a grad level course in AI agents, and the course requires that
I to do a project. One idea I have is to create a robot and have it do something
AI-ish. Since I'm not very adept with hardware, using a Mindstorms robot for
this seems ideal.

Before I pay $200 for the kit (which I might anyway...), I wanted an answer
to the following question. I cannot find an answer on the web, so I thought
I would just go ahead and ask here.

What I want to do is establish a system where the agent AI is hosted by a PC
(so I can write it in ruby or whatever without limitations); the robot
communicates remotely (no wires) it's sensory information to the PC, and
then the PC sends remote commands to control the robot.

Therefore, my question is: Is this possible to set up? If so, is it
relatively easy? I'm good with software, so its mainly the hw issue I have
questions about.

I thank you all for your patience and responses,
- Jake Baker
