1). I am envious...
2). Can you post pictures of the underside of the connector, the battery box
connector and the IR connector?
I would much appreciate it, thanks.

Here are the pictures of the Power Functions elements from the Bulldozer 8275,
including pictures of the plugs.
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=226241 (when modified).
You can see it's a 4-wire system. There are basically 2 wires for power and 2
for control. I'll give more details when I can.
There will be compatibility with the 9V system sufficient to allow existing 9V
motors, lights and leads to be used with this system. It will also be a route
to facilitate end-to-end connections. This is not yet obvious but, again, I
will post more details and pictures when I can.

hey mark,
thank you for posting all of this info. i look forward to seeing the gallery
but it seems to be taking forever to be moderated. is there a chance you could
post some deep links?

I'm guessing there's a video. If so, I would recommend putting the video in a
sub-folder by itself, as it is probably what is causing the delay.

Wow, that's very cool!
It's hard to get a sense of scale from the video -- how tall is the
robot?
What technology are you using for the balancing? I would think this to
be quite difficult with the standard NXT set, but maybe possible with
some additional third-party sensors.
Anyway, congrats on a very slick robot!

I can't say that I am a fan of the "permanent wires" or the connector end
itself, but perhaps I just don't like change. I wonder if there will be
extension cables for sale? Actually the more I think about it, the more I
forsee the attached cables being a problem (either too long or too short).
Thanks for the pics.

Hmm, I will add my voice in saying thanks for the pics. Definitely interesting.
I agree that I would prefer to have connector terminals on active
bricks, and not permanently attached cables.
What also I find awkward is that we now have divergence in Lego
connector styles, which is not a great thing. There is the old style
two core, which I can reasonably agree is no longer adequate. the NXT
connector, and this connector. It does not bode well for expanding
sets with compatible pieces. I realise that the NXT connectors are in
many ways not quite "Lego Like", but they are a very appropriate
connector, with good firm connections.
Will adaptor cables be available for this new style to be usable with
the NXT maybe? I would love to be able to connect that IR receiver
there to it.
One more thing (and I am in danger of having missed another thread if
it was mentioned there) - has the IR been figured out here yet? Is it
similar to the Manas protocol?
Cheers,
Danny

I searched for the dinosaur set on Brickshelf and got a fuzzy pic of the
box. Apart from the elements you mention there appears to be a white box
which could be a sound system. Can you explain what it is and how it
ties into all of this?

Thank you! I like the small(er) size of the motors; do the large motors also
have a stud recesses down one side? It actually looks in both bases as if the
pin connections are fairly well placed. I'm not overjoyed with the "hard-wired"
nature of these either, but with those small thin cables it does allow you to
mount these motors into tighter spots without worrying as much about leaving the
connector plug avalible (or, for kids, loosing the wires). It also looks like
the outputs from the IR system are color-coded? And since you called them the
"large motor" and "medium motor", well... can I hope?
Out of curiosity, have you tried the "magic motor demo" with these yet? It
certainly looks like you could stack outputs, which could be interesting.
Heck, this stuff is small enough that now my large-scale NXT-guided robot could
arry a small-scale ROV for "tight space exploring". Line-of-sight IR back to the
NXT carrier, then BT control back to my handset, with the whole thing visible on
video with my minispycam attached to the main chassis or ROV. Ideas, ideas...

All the pics should be visible now, at
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=226241
The large motors have 2 half-depth pin recesses on opposite sides. They are
designed primarily for a Technic beam interface because of their high torque -
other models might fall apart!
I held them in my rover robot by as many holes as possible because of this, and
chose a beams-and-plates chassis for better rigidity, as I expected studless
construction to warp with the torque.
The IR handset and receiver have red and blue outputs - 2 outputs controlled for
each of 4 channels in turn.
You can hope, as I do, but even if I knew, I couldn't tell you! :-)
The magic motor test doesn't have the same coupling ability as 71427 gearmotors,
probably because the gearing is so much higher with the new motors. The extra
power and torque at similar speed makes them a good substitute for 71427, 43362
or 47154 motors.
Outputs can be stacked, yes. Not sure too many large motors on one output would
work too well, due to ultimate current output limits, but I've successfully used
multiple medium motors on each output, in cases where it makes more sense to use
2 medium motors without gearing than one large one geared up. MOCs (to follow
soon) will illustrate this.
To interface the PF motors with the NXT, I guess the NXT 9V adapter cables are
the official way to go, since the PF system will have 9V compatibility. I'm
sure it won't take long for AFOLs to cut the leads :-)

yep you're right. i allready have a few mods planned. i'm going to see if i
can't fit a step motor into a train motor case among other things.

OK, I'm claiming retardism on my part for this next question:
I just don't see the compatibility between PF and 9V, can you elaborate?

I can't give too many details at the moment, but there WILL be a compatibility
between both systems, built in the extension cords.

AFAIK they will not be in the 2007 ferris wheel, dinosaur or bulldozer kits. I
don't have any news about a release date, nor about a place to purchase them. I
eagerly await developments and will let you know as soon as the information is
released.

Hey mark have you got any new info?
I just noticed that the bulldozer is out through S@H and want to know if the
adapters will be available there too. More importantly when. The official launch
date is just a few weeks away so surely it can't matter now.

Looks like i can answer my own question. According to the faq at customer
support the adapters will be out September 1st just like the bulldozer which all
ready is out. :) Good to know that it'll come out so soon.
I should point out that the email address in my posts is old. I've selected that
the adress should be hidden yet an old one appears. Will look into it.

Man, I'm excited. A few design flaws I can't understand though:
Why the cable nub coming out of the cable's brick? There has to have been a way
to avoid that.
On the large motor, why all that wasted space on the drkGry part that could have
pin holes? Also, I wouldn't say no to a wege-belt wheel pin-hole layout, for
the half-stud offset. Other than that, it looks good :D
On the small motor, it seems you would always need the pins on the front for a
strong connection, but oh well.
Looks good!
