NXTlog Sumo Events

Last weekend, several of us got together to run the NXTlog Sumo contest. I'm pleased to say it went very well: from more than 100 entries we reviewed and selected until we had almost 30 that we felt were worth building, and then built them, downloaded the users programs, & ran them in a double-elimination event at Steve Hassenplug's house. The results were impressive - on the whole, the field of entries did far better than I had originally hoped, and there were a lot of exciting match-ups during the day. Well, NXTlog has announced the winners here in their special events section. I'll try to post more of my thoughts and details on this event here or on NXTlog over the next few days, but for now, take a look at the results on the NXTlog page, and if you entered this, (or even if you didn't), please let us know what you think.

Congratulations to everybody who participated, & very heartfelt thanks to all who helped with the event in question - we had outstanding support from LEGO, NXTlog, and several individuals, both on the day of and prior to the event itself.

The winning robot at the end of the day was "MG_Sumo", which used a unique wedge made of free-pivoting upside-down backhoe scoops (pictured above). There were a lot of other good designs, with blades & scoops tending to dominate the field. Staying on the ring itself was a trick with many robots (it always is), but a really surprising number of builders seemed to have cracked this first hurdle (trust me, many don't).

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 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 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
