Snow Leopard issues - an interim fix

There have been a number of people who have had problems with the NXT-G environment installations, and the newest Max OS 10.6 (Snow Leopard). Installations that either don't work or don't seem to do anything, etc. There is a interim solution I've been told about, but I've not personally tested it, as (for various reasons) I've not installed 10.6 on my Mac as yet. But, here's the steps I've been told should allow NXT-G 2.0 to install on a 10.6 machine:
  1. Copy the contents of the installation CD onto the Desktop
  2. Open the copied folder and look under "Parts". Under Parts, location the "MindstormsUnivEdu.pkg" (if you are trying to install the Educational version) or "MindstormsUnivRet.pkg" (if you are working from the Retail install CD).
  3. Control-click (or right-click, if you have a two-button mouse) on the package, and choose "Show Package Contents" from the pop-up menu. This allows you to poke about in the normally "sealed" installation package.
  4. Go into the revealed Contents/Resources directory and delete the "preflight" file (toss it in the trash)
  5. Close this package and then run it like a normal install from this modified version on your desktop. Mindstorms NXT should install properly.
This is not by any means a permanent fix - LEGO and NI are working on that, and hopefully will have a patch or something to fix this properly. But hopefully this will allow the folks who have had trouble with 10.6 and NXT-G to continue playing.

Please let us know if this fixed your 10.6 problems, or brought up new ones.

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
