yes, cool idea.
I have a learning curve to
go through, but I'd be interested
in pursuing this.
Incidentally, it was that palm
kit mentioned on slashdot (actually
I got there via Wired.com)
that I'm waiting on...
acroname.com have created a kit
under licence from MIT as described
I've ordered but it's early days
and they haven't begun shipping yet...

(and off-the-wall again,
I read about different OS/firmware
for the brick, is anybody
pursuing porting embedded linux
or am I being dumb even asking?)

I'd still appreciate feedback on
the radio-control feature of the
cybermaster if anybody
has experience with it

I also found a reference to an O'Reilly
book on mindstorms that seems
to cover a lot of ground in detail
anybody have it? worth ordering?

sorry if this is turning
into "newbie-stream-of-consciousness-stuff"
but I was reading an article about
"swarm computing" (yeah, yeah, I hear you say...)
( http://www.linuxworld.com/linuxworld/lw-2000-10/lw-10-futurecomputing.html
)
and got to thinking about what could be achieved
with a number of rcx bricks, maybe,
to come back to your comment,
co-ordinated by a palm or pc...
kind of semi-autonomous but
"project managed"

Finally, though I'm late to the party
I gather the mindstorms kits
have been around for a couple of
years? What are lego working on?
What's the "next generation"?

  Re: Palm Hardware Interface idea?
 
Got some specs for the SV200 controller board that the PPRK uses: The SV203 is a Microchip PIC16C73 microcontroller based servo motor controller board. It accepts RS232 serial data signal from a host computer and outputs PWM (pulse width modulated) (...) (26 years ago, 2-Nov-00, to lugnet.robotics, lugnet.robotics.palm)

(...) It's basically the same serial data connection as the RCX. It just uses radio for transmission instead of infrared, so it goes around corners and has a longer range. Jürgen (26 years ago, 3-Nov-00, to lugnet.robotics)
