BrickFest report & sensors

Well I'm back from BrickFest, with a load of pictures, and an even bigger raft of new ideas. There were an amazing number of interesting LEGO creations there, and if you've never seen what truly talented people can do with LEGO, you might want to check it out. It was a real treat as well for me to finally meet some of the people that I have been corresponding with for almost a year in the MUP and MDP programs, and see their creations in person. There were also a lot of wonderful new news on about the NXT at the event, for instance...

First, LEGO announced that the HiTechnic sensors would be sold via LEGO Shop-at-home, as a "LEGO approved" product. In other words, these will be third-party sensors, but of such high quality that LEGO wants to move them through more official channels. This is not only great news for HiTechnic, but really interesting from the standpoint of being one of the first times LEGO Retail has sold a product developed & produced by a third party. Congradulations to HiTechnic, and thank you LEGO for opening up to yet more new ideas - this is an amazing step forward. Of course, this made me wonder about what FLL would consider an "official LEGO part". I suspect they can not be as flexible on this issue as LEGO is (unless FLL adds such sensors to the base kits), but it's an interesting development in any case. John & Steve actually seemed rather surprised at the applause from the community (most of the folks in the room were not Mindstorms types), but I was not - this is a tremendous step forward in LEGO working with the AFoL community, period.

Second, we (the MUP/MDPs) had several Q&A sessions during BrickFest. The questions that were asked were interesting to me (I noticed a lot of people simply not quite understanding data wires yet, for instance, and there were a lot of misunderstandings about BlueTooth), but in the "new information" category Ralph Hempel (developer of pbForth for the RCX, and one of the original MUPpets) announced that he has ported Lua (a C-like language) to the NXT! He demonstrated the core Lua (all running on the brick, not on the computer; the laptop was just a dumb terminal for these demos), including things like searching and ordering arrays of strings with blinding speed. He has a GDB stub working (all through the USB port, so no soldering onto the board of the NXT is required). Lua on the NXT is not yet ready for release: for one thing, Ralph is waiting for the firmware to go open source (I'd say "hint hint" here, but I already know LEGO is hurrying to do this... be patient, folks) so that the API for things like motors, the LCD, sensors, etc. can be worked in. But even still, this is a tremendous accomplishment, and points to yet another third-party firmware coming out for the NXT. Bravo, Ralph! I'll post a link when Ralph gets something updated. This was one of the most drool-worthy announcements for me at BrickFest.

The folks at NXTasy have done a great job covering events at BrickFest as well (you'll note all these videos are from them) - they have a video of Bryan Bonahoom's NXT playing Tic-Tac-Toe, as well as an interview with the folks at Minsensors showing off some of their new sensors, including a compass sensor (that I will be testing), and a device to use a gamecontroler as a NXT remote control - wonderful stuff! Check out these videos and enjoy living vicariously.

Finally, I also was able to try out a HiTechnic compass sensor - a very fun piece of technology, in a very nice-looking case. I'll report more on that presently. For now, browse and discuss amongest yourselves, while I decompress from BrickFest.

Oh, did I mention a NXTbot with live video streaming back to the computer? Thank you John Brost for that one.

Celebrating MINDSTORMS with a Remix - Part 3

The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these Fall and Winter remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Braill3 by Jerry Nicholls Braill3 is an EV3-based LEGO Braille bricks reader. This robot uses its fingertip, made from three touch switches, to read messages written using the LEGO Braille bricks and will speak out what it detected. If it sees a simple maths problem it will attempt to solve it and give the answer as well. To learn more about the process of creating this machine, read Jerry's blog . Braill3 can be viewed here . Set Review: The Braille Bricks set is well thought out. The ratios of the letters is suitable for general use and the addition of some punctuation and arithmetic operators is excellent. There is a card showing what bricks there are and their quantities, but no form of sort...

Celebrating MINDSTORMS with a Remix - Part 2

The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these summer and fall remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Remote controlled material handle r by Jozua van Ravenhorst (aka Mr Jo) This remix combines the LEGO Technic Material Handler (42144) with MINDSTORMS EV3 (31313) It uses the power of pneumatic cylinders to move objects around. By using a bluetooth remote control, very precise movements can be made with this model. Touch sensors in the base chassis prevent the turret twisting the cables that go through the turntable to much. The program has several protections to prevent over pressurizing the system for each of the 3 individual pumps and valves that control the 2 booms and claws. The real version of this machine is mostly used in waste material sites to bring the material to machines that sort and...

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...
