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?

2023 is the 25th Anniversary of the MINDSTORMS brand. For 25 years, MINDSTORMS has educated and inspired a generation of robot builders, both children and adults. Unfortunately, the LEGO Group decided to end the line on December 2022. Many ROBOTMAK3RS have been passionately involved with the development of MINDSTORMS through the MUP and MCP programs. Even with the newest Robot Inventor line, several ROBOTMAK3RS were invited to submit additional bonus models that were included in the official app. Regardless of the retirement of a major LEGO robotics product line, ROBOTMAK3RS continue to MAKE-SHARE-INSPIRE using all LEGO robotics platforms available to us. Here is the official statement from LEGO. Since its launch in September 1998, LEGO MINDSTORMS has been one of the core ‘Build & Code’ experiences in the company’s portfolio, carrying with it significant brand equity and becoming a stand-out experience for the early days of consumer robotics and leading to current Build & Code

Celebrating 25 Years of MINDSTORMS

In celebration of the 25th Anniversary of MINDSTORMS, we take a trip through history. Please also visit ROBOTMAK3RS Community every week as we highlight different projects all through 2023 in celebration of the anniversary. Some of the early history is based on the content shared by  Coder Shah  in our  MINDSTORMS EV3 Community Group . Some of the text and links may have been edited from his original posts for consistency and clarity.  1984 - Kjeld Kirk Kristiansen watched a TV program called "Talking Turtle," where MIT professor Seymour Papert demonstrated how children could control robot "turtles" using LOGO, a programming language he developed. 1988 - The collaboration between MIT and LEGO resulted in LEGO TC Logo in 1988, which allowed students to control LEGO models using computer commands. The video shows Papert demonstrating TC Logo. 1990 - LEGO TC Logo was hampered since the robots you built had to be tethered to a personal computer. LEGO and MIT

Celebrating MINDSTORMS with a Remix Part 1

In honor of the 25th Anniversary of MINDSTORMS, we asked ROBOTMAK3RS to combine a LEGO set of their choice with a MINDSTORMS set. Here is what these five ROBOTMAK3RS came up with.  MINDSTORMS Chess Assistant by Arvind Seshan Overview: When you are new to chess, it can be a challenge to remember which pieces go where. Now, you can use machine learning and LEGO MINDSTORMS Robot Inventor to build a tool to help you learn where all the chess pieces go on the chess board. Sets used: LEGO® Iconic Chess Set (40174) and MINDSTORMS Robot Inventor (51515) Review: I really like how the chess set base can store all the pieces underneath and that the board neatly splits in half for handy storage. The chess pieces themselves are very sturdy and well built. My only criticism is the building of the box itself. It was quite difficult to see what pieces to use and since the entire box is made mostly of thin plates, it took a lot of time and patience. I would have liked the storage area to be sliding dra
