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 :).

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
