Here's a quick project I've been playing with.  It is a NXT trike built around
the NXT and the large power puller wheels.  It is controlled remotely from
another NXT via bluetooth.  Not much else to say, check out the pictures on
NXTlog here:

and I uploaded a video to youtube

Some day I'll figure out an actual USE for the ultrasonic sensor on the front,
but for now, it just looks cool!

Honestly, I think this whole bluetooth remote control functionality is the best
part of the NXT.  For some reason, making a $500 remote control car out of LEGO
is just so much fun.

That is pretty sleek!  I can't believe I don't have two of these yet.  (Come to
think of it, I don't even have one yet.)

But if you activated the ultrasonic sensor, it would probably tell the NXT
"watch out, there's a BIG TIRE right in front of us!!!"

Ha ha, that is a valid point.  I don't THINK it will be a problem (there I go,
thinking again),  The angle of the pictures makes it a little questionable, but
if I remember the specs I saw on the US sensor, I don't think the area of
sensitivity in the vertical plane spreads out quickly enough to "see" the tire.
At some point, I'll test the theory.

Hey John,

That's a really nice bot. I'd like to write an NBC program to make it autonomous
using the Ultrasonic sensor. Have you thought about posting building
instructions or at least pictures showing how you built it?
