Competition Discussion & Questions

I was playing around with one of my bots today that uses the Play/Record block an unusual thought popped in my head. Let me see if I can explain it...

Let's say you have a competition where your bot must navigate a fixed-dimension field (let's say 10x10 feet). Let's also add in the fact that there are obstacles and objects to interact with on the field. (Can you tell I'm trying to avoid using a 3-letter acronym here?)

Finally, let's add in the fact that the bot will always start from the same exact position.

Okay, here's the question:

(Assuming memory isn't an issue, because it may very well be in the REAL WORLD)

What's to keep me from setting up a test field, putting in a Play/Record block configured for 5 minutes (300 seconds) and then recording my manually moving the bot around the field, interacting with objects, performing tasks, and then returning home?

If everything is in a fixed location, all I've got to do is drive the bot with my hand into the proper position for a task, use Motor A if required and move it to perform a task, and then move it on to the next task.

I realize that there might be subtle differences in measurements, but if we're dealing with a table of less than 10 feet, the bot probably won't encounter any major problems with playing back the recorded file. If I needed the bot to interact with objects with a degree of accuracy in the millimeters, I could see a problem, but I haven't seen too many competitions with that level of fine-tuned design.

Okay, thoughts? Is this allowed? Impossible with the current memory limits? What if memory isn't an issue by the time competition rolls around?

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


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
