Tribot Sumo and others...

Beside building Bulldozer-based sumo robots, the "Robotics Posse" also built a few other sumo robots during our sumo event, starting with a speed Tribot build-off. LEGO claims you can have a working robot in 30 minutes... so we tested that. The fastest Tribot build was Steve Hassenplug, with a time just a shade over 10 minutes... and everyone in this picture completed a working Tribot in 20 minutes or so. I'd say the LEGO claim is a fair one. In case you think this was stacked in favor of adult builders, the young man in the background is my son: Ben is 10 years old, and had never put the Tribot together before.

Once we had five brand spankin' new Tribots, we immediately reprogrammed them for sumo, and did slight modifications to them, adding front attachments or modifying the back caster, but that was about it. "Semi-stock" Tribot sumo was actually a very good time - some had wicked-looking front weapons, some tried to flipped the opponent, and some actively looked for targets. But of course, we didn't stop with Tribots. How about Tribot vs. Alpha Rex? Or Tribot vs. a Bulldozer? Or other odd match-ups? Well, here's a video, showing the results of some fun (if chaotic and always unpredictable) NXT-based sumo:

Steve Hassenplug will be putting some more up about this event on his website here over time. Perhaps some of you will be inspired by this to enter the NXTlog Sumo event as well. I certainly am...

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

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
