Two Students at TU Vienna (Alexander and Peter) have designed and
built a very nice board to interface an FPGA (running JOP) with the
LEGO Mindstorms system. Take a look at
http://www.jopdesign.com/wiki/index.php?title=Lego_PCB and also
check their web site at: http://stud3.tuwien.ac.at/~e0327019/lego/
for the feature list and images.
The board is a major step towards building FPGA based robots :-)
The design file is placed as open-source and you're free to build
your own PCB. For those of you who don't want to solder your own
board (like me) we can arrange a production run of several boards
with a professional company. Please reply to the list (or to me)
when you are interested in such a board.
The very rough estimate on the cost for the board is EUR 100,-
However, that depends also on the number of boards we will produce.
Cheers, Martin

It sounds neat, but to be fair, FPGA bots have been pretty easy to build
for a while -- look up the BotBall "XBC" controller.

ok, I'm quite new to the robots scene. I regret about this statement ;-)
Do you have some links to FPGA/Mindstorms projects.
My intention was to get a Mindstorms interface for my Java processor
to give students a chance to learn some Java real-time programming.
Cheers,
Martin

Please log in for more thread options Hi
That sounds like fun!
I remember seeing that FPGA XBC controller some years ago, and wondered
"How can I design and build such an FPGA?", because the cost to buy such
a controller is prohibitive.
And recently I have been surfing the Web looking for info on FPGAs.
www.fpga4fun.com
There are some cheap little Altera & Xilinx programming hardware around:
www.knjn.com
If someone can throw some leads my way about designing such an FPGA for
a robot that would be great, as I bought an old game Boy Colour that I
would like to hack, similar to the XBC. Or building a stand-alone FPGA
robot system.
It would be cool to build something like that for a digital design
course at technical college.
Cheers

Please log in for more thread options Hi again
This looks very interesting, I took a quick peek. And will check it out
later in detail.
However, were you aware that a Java Virtual Machine has been available
for the RCX for several years?
Alternative operating systems have been around for years.
There are books available on the subject. And resources on the WWW.
Also, it is possible to program efficiently in C. Once again books are
available.
Can also be programmed in Visual BASIC, Forth, etc...
Why waste a perfectly good 16-bit processor, the Hitachi H8?
Doesn't make sense to me to re-invent the wheel, when there have been
alternatives for years.
I am not knocking the FPGA development, in fact it looks cool, I just
was curious if you were aware of many alternatives to the native RCX
programming system that make use of the 16-bit Hitachi CPU?
Cheers
:-]
