NXT-G 2.0 : Datalogging

I was very lucky to attend one of the recent LEGO engineering conferences in Brisbane, organised by LEGO Education and presented by Melissa Pickering from Tufts University (home of RoboLab)

One of the highlights was a quick demonstration of NXT-G 2.0, which will include a specific datalogging section. No screenshots are available as the graphical interface is still under development, but they are looking at a January 2009 release date.

It looks great and has two levels to it that I could make out. The first level requires no blocks whatsoever, rather it opens a dialog box asking what sensors you have connected to each port and for how long you wish to sample. This suits a handheld logging experiment as you cannot move motors or perform other actions while logging. The second level introduces a 'datalogging' block which does the same thing, and include it with all your regular blocks in your program so you could drive a robot around, collect some data, move to another spot and collect some more data etc.

If you are connected to your computer when taking data (bluetooth or USB)
NXT-G 2.0 will show a realtime graph of the data being collected. One of the nifty features they showed was the 'predict' mode, whereby teachers could pose a question about what shape a data set would look like, students could then 'predict' what the data would look like by using a pencil tool to draw it out, and then run the experiment over the predicted data to see how closely they matched. All data will be exportable in text file format for analysis with other programs (excel etc)

The other big change that was presented was 'exportable' myblocks. This means that if you are using myblocks, you just save your file as normal, email it to whoever you want, and the program will run without needing to send the individual myblocks as well.

NXT-G 2.0 is being released by LEGO Education, not LEGO Retail, so it may be a little more difficult to find. They will be including 4 projects with the software, the most impressive being a probe dipper that can raise/lower a probe into a beaker and also rotate between beakers.

Overall it looks great and I can't wait to get my hands on it.

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
