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?
