I don't know if someone got this post but since I couldn't find it on the
lugnet site then I guess it got lost somewhere. Here it goes again:
> With Bluetooth at least we'll have access to potentially a whole
computer's worth of memory (at a slower rate? I really > need to learn about
Bluetooth).
I have a Nokia 6230 with bluetooth and it has a mmc expansion slot, which
means that you can add more memory than the one inside the phone. I have a
512MB memory card filled with MP3 on the phone and I'm not sure if it's new
firmware supports the bigger cards (1-4Gb). Anyway, by creating an interface
between the phone and the NXT over Bluetooth we could access that whole lot
of memory for whatever purpose we want. With some skillful programming we
could even use the built-in video camera capabilities and even make a global
swarm of NXT over GPRS. It would be just like Terminator 3...

Jonathan

As I cannot find this here is CNET's review:
http://news.com.com/Lego+Mindstorms+no+kids+toy/2100-1041_3-6020603.html
"Lund demonstrated, for example, how with his Bluetooth phone, he could direct
the movement of one of the robots. Then he showed how the robot was programmed
so that when it moved and bumped into something, it would send a signal to his
phone directing it to snap a digital photograph."
Follow the Photos link and image 2 shows another contraption besides the slot
machine. It's too bad that we can't see the other half of the table.
This may be a repeat too, but Engadget has video too that shows the other
contraption.

Ugh.. she mentions communicating to the NXT with J2ME on your phone.
Seriously depressing that I might have to learn Java. That is one
bandwagon that I have long avoided.

Me too and I work for Sun! My life plan to never program in COBOL is working
out (now that we're clear of Y2K), but Java might be harder to avoid.

Just because you'll be using a JVM doesn't necessarily mean you have to
program in Java. There's a chance some other compiler capable of
targeting the JVM might provide a neater language:
http://www.robert-tolksdorf.de/vmlanguages.html
I'm not sure how many of those might be compatible with J2ME, however.
I don't use Java myself.

You don't have to use Java to communicate over Bluetooth. Well perhaps if your
only bluetooth device is a phone. But if you're using a Bluetooth enabled PC
there are many options.

I'm curious... What is it about java that you want to avoid? Is it just
that you perceive it as a band wagon that everyone and their brother is
jumping on to look cool?
I can see that about it. And things like that have made me avoid things
in the past too, so I don't blame you. However once I actually looked
into Java, and started to use it, I wished I had used it sooner. Anyway
to each his own... I was just curious.

My current project involves dealing with mobile devices and understanding their
development frameworks. I have found J2ME to be an excellent platform to
develop apps but is still not quite complete. The issue is mobile devices have
gotten more advanced but the core J2ME hasn't rapidly folded in more standard
feature sets from its big J2SE big brother (the base MIDP/CLDC profile is bare).
Things like security, web services, messaging, even local filesystem access are
part of optional JSR's and not the core J2ME spec, i.e everyone's phone could
have a different implemented profile of a J2ME runtime (so my Treo might have
web services client side support while your BlackBerry might not but it might
have the Mobile Media API).
IBM seems to offer the most complete environment with their Workplace Anywhere
tooklit which contains the core JVM (KVM), various J2ME extensions, and a
streamlined Eclipse IDE for J2ME development. Anyone interested should check
out their site.
I think one interesting project would be to create a library (appropriate for a
J2ME environment) that abstracts the functionality of the NXT. I'm not sure if
there are already APIs defined in various JSR's that apply and the only thing
left is to write the backend (JNI in C) reference implementation. Perhaps Lego
already has such an interface for phones, not really sure.
Well, its food for thought...

We have yet more video of Mindstorms NXT:
http://electronics.howstuffworks.com/ces-2006-video.htm
This video has Alpha Rex dancing and dancing faster as the decibels go up. You
will also see the Lego presentation playing in the background, especially when
the camera points up at the robot for better light. But the resolution is small
and it is dark when focused on the people.
Further down on the linked page is Vex Robotics presentation. Unfortunately,
this robot will capture the Robot Wars crowd more easily with metal parts and a
remote control with standard R/C crystals. Remote Control also means
"Build-and-Use", no programming and PC required.
Thinking about Studless beams, NXT now looks a lot like Vex. NXT has THE
versatile parts set. Vex blows away NXT with 6 Interrupt inputs, 16
Analog/Digital inputs, and 8 motor outputs (who needs multiplexing?). Vex's
effectively 4 touch sensors pale next to NXT's 4 sensors. The only Vex Accessory
that LEGO does not have a counterpart is the Omnidirectional Wheel.
Can someone tell me if Vex's 1 servo and 3 motors give feedback to the brick?
I really believe that a standard BlueTooth R/C control program for celphones is
needed. As a standard NXT program, you would get instant "Build-and-Use". It
won't be "Just as Good" as Vex, but would be a great selling point.

As nobody else has bothered to dredge this up, CES did have the box and Jeff at
nxtbot.com took a picture of the inside flap.
I can make out:
2 books and CD,
2x long, 2x med, 1x short wires
Sensors, motors, NXT brick
Row under brick may have fifth wheel, unsure about 4 parts under brick, but red
and black ball on right.
Various studless beams in next three rows. Does not appear to have many angled
control arms.
Smaller parts from bottom five rows could be postulated from models we have
seen.

WOW! I haven't even seen the box! That is really cool. Looks like LEGO is
ready to go...I'm wondering if the release date will indeed move up instead of
back...I certainly hope so!
