Thank you! The controls started out unintentional - I really wanted to use the
NXt motors with encoders for other functions, so started out with just the XL PF
motors. But as it is, it works great. It actually allows a third dual-control
mode as well, where the user "drives" it around, and once a target is detected
"within range" the NXT can take over control and do an automated firing
sequence.

Thanks - the videos take a little bit of time to put together, but it's kind of
like photographing MOCs... there's a fun creative aspect to the documentation
that I enjoy as well. And really, for most of my creations showing them in
motion is really the only way to begin to get a feel for them. I've actually got
a very poor stop-motion assembly sequence for this critter that I need to slap
together. I didn't have enough time to photograph enough frames properly, but it
should still be sort of fun to watch. I've got most of the still images up on
Brickshelf now, so if anybody wants to build it they can replicate it from the
(large number!) of pictures:

It's very handy. With a single IRLink, you can control all four channels of the
PF system, giving you 8 PF motors to work with. While you don't have built-in
motor encoders, the IRLink can control the PF system at 8 different power
levels, much better than you can do with the PF Remote currently (the remote
only allows three states: On Fwd, On Rev, and Stop). The slow panning turns that
Ogre does under NXT control aren't an option with the PF remote.
> ...and YOU sir WOULD have a Black NXT, bravo.
Story: This got carried by Gizmodo (boy does that drive up the YT hits), and I
dropped in at one point to see the comments. My favorite was from Purple Dave,
who was commenting about the model and then realized who had built it, and added
comments to the effect of how surprised he was... knowing me, and my "Rainbow
Warrior" building style (his words, not mine), he was very pleasantly surprised
how color-coordinated it looked. He's right, I've got a real "function over
form" mindset, but now and then, I rise above it... and the black NXT just
worked perfectly in such an "aggressive" color scheme.

| Mr. Davis! I just watched the video, AND IT IS AWESOME! That combination of controls is fantastic. I am really glad you posted this creation. I couldn't get over the way the thing shoots! It is utterly _!_ridiculoid_!_ LOL! <3 I really like the (...) (16 years ago, 22-Mar-09, to lugnet.robotics)
