Multi-Bot for NXT 2.0

The Multi-Bot project for NXT 2.0 from nxtprograms.com is a robot vehicle that can take a number of different forms, including taking on several different modular attachments that can be used individually or combined in various ways, all using a single NXT 2.0 (8547) kit, or equivalent/replacement parts from other NXT/Technic kits.

Multi-Bot was designed to be a flexible "teaching robot" of sorts for NXT 2.0, especially as an aid to learning NXT-G programming, as you can use it to do a lot of classic robot vehicle tasks and expand it to do your own tasks. Home users of NXT 2.0 might find it a good way to learn about the basics of robotic vehicles, and especially in conjunction with the CD (see below) as a good way to learn a lot of NXT-G programming. FLL teams that have the 2.0 retail kit (8547) or equivalent parts and software might also be interested in using it as an educational tool before the regular FLL season starts or at the beginning of the season.

Building instructions for Multi-Bot, its variations, and several different attachments using all the standard NXT 2.0 sensor types are available on the web site. In addition, over 70 ready-to-run and fully commented NXT-G programs for Multi-Bot are available on the CD LEGO MINDSTORMS NXT 2.0 by Example. The programs range in complexity from beginner to advanced and cover different ways to control the motors, use the sensors, and more. The program descriptions are also included on the web site. Users or teams with some programming experience may want to see if they can develop similar programs on their own given the descriptions. Or if you like learning by example, get the CD and study the programs in each section (which are arranged in increasing difficulty) to learn NXT-G programming with ready-to-run examples all using Multi-Bot. Since you can quickly reconfigure Multi-Bot for the different tasks, you can cover a lot of programming topics without a lot of rebuilding.

Here is a video showing the included attachments for Multi-Bot and video clips showing tasks from selected programs on the CD:

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 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...
