Lego Mindstorms NXT - Wikipedia, the free encyclopedia. The base kit ships in two versions: the Retail Version (set #8. A new version of the set, the new Lego Mindstorms NXT 2. Lego Mindstorms NXT Includes: * 519 specially selected Lego Technic elements * Three interactive servo motors * Built-in rotation sensors to for precise control * Ultrasonic visual, sound, and touch sensors * Improved light. This is the 'Line Follower' project for NXT 2.0 from nxtprograms.com. See free building instructions and programs at http://www.nxtprograms.com/NXT2/line. LEGO Mindstorms NXT is a programmable robotics kit released by Lego in late July 2006. It replaced the first-generation Lego Mindstorms kit, which was called the Robotics Invention System. The base kit ships in two versions. August 1, 2. 00. 9, featuring a color sensor and other upgraded capabilities. There is now a new Lego Mindstorms Robot, called the EV3. NXT Intelligent Brick. It can take input from up to four sensors and control up to three motors, via a modified version of RJ1. RJ1. 1 phone cords. The plastic pin to hold the cable in the socket is moved slightly to the right. It has a 3. 2- bit ARM7. TDMI- core Atmel. AT9. 1SAM7. S2. 56 microcontroller with 2. KB of FLASH memory and 6. KB of RAM, plus an 8- bit Atmel AVRATmega. It also has a speaker and can play sound files at sampling rates up to 8 k. Hz. Power is supplied by 6 AA (1. V each) batteries in the consumer version of the kit and by a Li- Ion rechargeable battery and charger in the educational version. The Intelligent Brick remains unchanged with NXT 2. With the help from the Mindstorms Community Partners (MCP), LEGO has released several bonus models for the NXT 2.0 set. However, they are not easily found on the LEGO website. This page is a collection of pictures. The projects on this page are designed for the LEGO MINDSTORMS NXT 2.0 (8547) kit and software. No extra parts are required. These projects cannot be used with the NXT 1.X kits (see instead the. A black version of the brick was made to celebrate the 1. Mindstorms System with no change to the internals. Firmware and developer kits. More complicated programs and sound files can be downloaded using a USB port or wirelessly using Bluetooth. Files can also be copied between two NXT bricks wirelessly, and some mobile phones can be used as a remote control. Up to three NXT bricks can communicate simultaneously via Bluetooth when user created programs are run. The retail version of the kit includes software for writing programs that run on Windows and Mac OS personal computers. The software is based on National Instruments. Lab. VIEW and provides a visual programming language for writing simple programs and downloading them to the NXT Brick. This means that rather than requiring users to write lines of code, they instead can use flowchart like . With careful construction of blocks and wires to encapsulate complexity, NXT- G can be used for real- world programming. The language supports virtual instruments for all LEGO branded and most 3rd party sensors/components. Version 2. 0 contains new tutorial challenges, a remote control, custom graphics and sound designers, and new LEGO color sensor support. Community support is significant, for example: http: //www. C# with Microsoft Robotics Developer Studio. Also, as Bricx. CC was originally made for the RCX, programs for it can be written using NQC via Bricx. CC. Different firmwares can be flashed to the NXT using Bricx. CC. Bricx. CC has many utilities such as Ne. XTExplorer (upload/download files, defragment the NXT, use file hex viewer), Ne. XTScreen (view what's on the NXT's LCD, and capture images and video). Next Byte Codes (NBC) is a simple open source language with an assembly language syntax that can be used to program the NXT brick. Bricx. CC also has the capability to decompile standard . NXT executables to NBCNot e. Xactly C (NXC) is a high level open- source language. It can also be used to program the NXT brick. NXC is basically NQC for the NXT. In NXC, even creating video games for the NXT is possible. Some people have even got working grayscale on the NXT Screen. Robolab. Version 2. NXT brick. Lego has announced that it will stop officially supporting Robolab but Robolab 2. The strength of Robo. Mind is the compactness of the learning environment, which allows to quickly develop and test scripts in a virtual environment. The scripts can then directly be transferred to a Lego Mindstorms NXT robot, to see the result in real life. The resulting NXT programs have the compactness and clarity offered by that programming environment. Carnegie Mellon Robotic's Academy, ROBOTC is a programming- language based on C for VEX, the new VEX Cortex, FIRST Tech Challenge, and Lego Mindstorms. ROBOTC runs a very optimized firmware which allows the NXT to run programs very quickly, and also compresses the files so that you can fit a large amount of programs into your NXT. Like other NXT languages, ROBOTC requires this firmware to be downloaded from the ROBOTC interface in order to run. NXTGCC is a GCC toolchain for programming the NXT firmware in C. JOS NXT. It can be used to control Lego NXT robots over a Bluetooth serial port (serial port communication is part of the base functionality of MATLAB) or via a USB connection; for example using the RWTH - Mindstorms NXT Toolbox (free & open- source). Simulink is a block diagram environment for modeling and simulating dynamic systems. Using Simulink, a user can design and simulate control algorithms and LEGO systems, and subsequently automatically program the LEGO NXT or EV3. Support for programming the Lego NXT or EV3 only requires Simulink and is available at no additional charge. MATLAB and Simulink Support for LEGO MINDSTORMS programming is freely available. More information found at: LEGO MINDSTORMS Support from MATLAB and Simulinkpb. Lua is a port of the Lua programming language, a general purpose scripting language, for Lego Mindstorms. A port of GNAT is available for the NXT. It relies on a dedicated run- time kernel based on the Ravenscar profile, the same used on the Goce satellite: this permits to use high- level Ada features to develop concurrent and real- time systems on the Mindstorms NXT. URBI is yet another language and is a parallel and event- driven language, with interfaces to C++/Java and Matlab. It also has a component architecture (UObject) for distribution. Urbi is compatible with many robots, including Nao (cf Robocup), Bioloid or Aibo. It uses NXT- G and . It is unknown if you can legally implement this in FLL competitions. Unlike the other languages for the NXT the code is not compiled to a binary file. Instead the code is directly transmitted to the NXT via a Bluetooth connection. Robotics. NXT. It supports direct commands, messages and many sensors (also unofficial). It has also support for a simple message- based control of a NXT brick via remotely executed program (basic NXC code included). Lib. NXT is a utility library for talking to the Lego Mindstorms NXT intelligent brick at a relatively low level. Lib. NXT is targeted mainly at the platforms that the official Lego Mindstorms NXT software overlooks, namely Linux and other unices. It will work on any POSIX- compliant operating system where libusb 0. Windows support is also possible with the win. C. The library allows users to control a Lego NXT via bluetooth controller from within other C programs. The library provides low level control and high level abstraction. The library only runs on GNU+Linux. Py. NXC is a project which converts Python code to . It supports direct commands and several aftermarket sensors. LEGO Mindstorms EV3 Software. It supports direct mode and compiled mode. Sensors. The orange Enter button and the gray right and left NXT buttons can be programmed to serve as touch sensors. In the NXT- G programming software, a value of 0 is given out when it is not pressed, and a value of 1 is given out if it is pressed down. The light sensor can sense reflected light values (using the built- in red LED), or ambient light. In the NXT- G programming software the sensor senses light on a scale of 0 to 1. It can show the distance in both centimeters and inches. The maximum distance it can measure is 2. The ultrasonic sensor works by sending out ultrasonic sound waves that bounce off an object ahead of it and then back. It senses the time it took for that to happen. In the software (see Programming above), people can decide what to do with the information that comes from the sensors, such as programming the robot move forward until it touches something. Vernier produces data collection devices and related software for use in education. The analog interface is backward- compatible (using an adapter) with the older Robotics Invention System. The digital interface is capable of both I2. C and RS- 4. 85 communication.
