NXT nibblets

I keep ending up with a list of things to mention, but not enough time to do it (or not enough material for a full post), so here's a brief roundup of a few things. So in no particular order...

The HALE mission has put out a nice YouTube video, showcasing some of the video as well as the still photos from the ground team end of the mission. It also gives (at the end) a run-down of some of the faces & names involved. Take a look, and enjoy the music & presentation.

Steve Hassenplug has come up with a novel robotics game he's named "PSumo" (for "programmable sumo"). The idea isn't to make fantastically complicated or fast sumo robots, but instead to make a series of nearly equal robots that casual observers can "program" by using RFID cards swiped by a sensor on the robot. It was a huge hit at the recent Brickfair event on the east coast, and I'm sure we'll see it a lot of other places. We'll probably have a detailed blog post on this soon.

A number of people have asked for plans or more details on my recent PnP arm, wanting to duplicate it or at least understand it better. While the odd, very-non-rectangular geometry makes it difficult to reproduce in LDD, I did do the arm itself and a partial attempt at a loading pallet. I've put those up along with some images and a stripped-down NXT-G program & video up on NXTlog, for anyone who wants to try it. Let us know what you do with it.

Here's a novel physics demonstration (hey, I'm a physicist, what did you expect) of non-linear resonance. Want to make a pendulum stand up the wrong way? Vibrate the support point fast enough, and you get an interesting effect...

Finally, what do you get when you couple something like Jim's camera platform with heavy metal? A camera panohead that looks like the NXT was grafted on to a butchered store display frame, but it works :).

MINDSTORMS Retires!

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
