Thoughts on NXT vs. RCX in competition...

Read Filip's comment (about power) for the earlier post on weight, and you may be wondering how in the world can an RCX bot compete with an NXT bot?

From a power and weight perspective, one of the 'balancing factors' I can imagine (for now) is the number of extra sensors and more powerful motors that can be made/purchased for the RCX. If you are talking about an 'anything goes' competition, the NXT is at a disadvantage due to lack of additional sensors and motors. But we can't expect this to last too long...

Another 'balancing factor' could be the experience factor. There's a lot more trial-and-error testing with the RCX, and it could be argued that inexperience with the NXT system could help the RCX designer(s). If LEGO Education NXT releases its version in August 2006, the experience factor will last only as long as the time needed for the NXT developers to catch up - could be months... or a year or more.

If you examine the last set of challenges for the FLL, it may or may not be difficult to imagine performing the tasks with the NXT. Lack of 'hands-on' with the NXT is what keeps me from writing 'no problem' - who knows, some of the tasks for RCX may truly be difficult or impossible (?) for the NXT - and by that, I mean the basic retail kit and/or Education version.

I have no doubts the NXT is going to be a powerful robotic construction system... my question is simply whether we should even be comparing the NXT with the RCX? I still tend to think of the two as apples and oranges and, therefore, comparisons cannot be fair to either product.

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

Celebrating MINDSTORMS with a Remix Part 1

In honor of the 25th Anniversary of MINDSTORMS, we asked ROBOTMAK3RS to combine a LEGO set of their choice with a MINDSTORMS set. Here is what these five ROBOTMAK3RS came up with.  MINDSTORMS Chess Assistant by Arvind Seshan Overview: When you are new to chess, it can be a challenge to remember which pieces go where. Now, you can use machine learning and LEGO MINDSTORMS Robot Inventor to build a tool to help you learn where all the chess pieces go on the chess board. Sets used: LEGO® Iconic Chess Set (40174) and MINDSTORMS Robot Inventor (51515) Review: I really like how the chess set base can store all the pieces underneath and that the board neatly splits in half for handy storage. The chess pieces themselves are very sturdy and well built. My only criticism is the building of the box itself. It was quite difficult to see what pieces to use and since the entire box is made mostly of thin plates, it took a lot of time and patience. I would have liked the storage area to be sliding dra
