Behind the scene look at LEGO® TECHNIC design process
I have spent a big part of this month robotizing the new LEGO® TECHNIC bulldozer that came out early this month. My children and I have had great fun adding a LEGO® MINDSTORMS NXT brick to the bulldozer and managed to control the Power Function motors with the NXT and adding sensors to the bulldozer so it can be semi autonomous. [View previous blog].

I am really impressed by the attention to detail that has gone into the Bulldozer design. Today I came across this brand new video on the LEGO® Bulldozer web site that has just been posted there:
It is an excellent in depth look at the design process that happens when a new TECHNIC model (i.e. Bulldozer) is dreamt up. Click here to view it.
The following still from the video shows various alternate designs of the bulldozer that never made it.

This must be a dream job! What will you design if you have 6,500 different LEGO elements to chose from?
Edit (following DAG's comments):
Sketch models:
Thank you David, for your comments. I have tried to capture the closeup of nearly all of the sketch model the LEGO designer created from the movie. I hope this is what you were after:
(a) Bulldozer 1:

(b) Bulldozer 2:

(b) Bulldozer 3:

(c) Bulldozer 4:

(c) Bulldozer 5: pneumatic version - no motor

Here is a challenge for people who have the new TECHNIC Bulldozer. How many of the above models can you create without an instruction manual?

However, the video is too fast - I wish I could see a closeup of the model that the guy made in more detail..

I wonder how supply will be for xmas?
Mostly, it's of the 'dozer smashing through a wall. As well as a DAZLR-derived Zamor shooter, taking out a wall at about 7 balls per second, only to have the rest of the installation trashed by Packbot driving through it.
Huh. I seem to be slightly distructive now that I think about it.

I know there are dozens of videos made by people who had bought the Bulldozer. But what is unique about this video is the fact that it is a lego video and features a senior design guy from lego. Thats all.

I had a few offline messages saying the flash video link to LEGO site does not work. If you get that problem, please try again after a while (assuming you have the latest Flash player etc.)

To me it looks like a cross between a Caterpillar D-11 and a D9 with a modified ripper.
