The base kit ships in two versions: The third generation, the EV3 , was released in September It can take input from up to four sensors and control up to three motors , via a modified version of RJ12 cables, very much similar to but incompatible with RJ11 phone cords. The plastic pin to hold the cable in the socket is moved slightly to the right. Power is supplied by 6 AA 1. A black version of the brick was made to celebrate the 10th anniversary of the Mindstorms System with no change to the internals.
Lego has released the firmware for the NXT Intelligent Brick as open source , along with schematics for all hardware components. 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. This means that rather than requiring users to write lines of code, they instead can use flowchart like "blocks" to design their program. With careful construction of blocks and wires to encapsulate complexity, NXT-G can be used for real-world programming. Community support is significant, for example: BricxCC also has the capability to decompile standard.
It can also be used to program the NXT brick. Some people have even got working grayscale on the NXT Screen. Lego has announced that it will stop officially supporting Robolab but Robolab 2. RoboMind is educational software that is specially developed to teach students about logic, programming and robotics. The strength of RoboMind 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. More information found at:. It relies on a dedicated run-time kernel based on the Ravenscar profile , the same used on the Goce satellite: 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. Ruby-nxt is a library to program the NXT for the Ruby programming language. 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. 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.
Windows support is also possible with the win32 port of libusb. 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.
It supports direct commands and several aftermarket sensors. Physical Etoys is a visual programming system for different electronic devices. It supports direct mode and compiled mode. The sensors come assembled and programmed. 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.
Lego also sells an adapter to the Vernier sensor product line. Vernier produces data collection devices and related software for use in education. Sensors are connected to the NXT brick using a 6-position modular connector that features both analog and digital interfaces.
The analog interface is backward-compatible using an adapter with the older Robotics Invention System. The digital interface is capable of both I 2 C and RS communication.
Lego Mindstorms NXT 2. The set contains pieces, including a new sensor that can detect colors. Parts can be ordered separately. In the original kit, the sensors included are the color sensor, two touch sensors, and an ultrasonic sensor:.
In order to create larger, more complex programs, programming software on a PC is required. The standard programming software is NXT-G, which is included in the package. Third-party programming software is also available, some of which is listed below:. NXT-G is the programming software included in the standard base kit. It features an interactive drag-and-drop environment.
Since its release, several bugs have been found and new sensors have been created. While the toolkit does allow for the creation of new sensors, National Instruments has yet to formally release an update.
It requires nxtOSEK to run. RoboMind is an educational programming environment that offers a concise scripting language for programming a simulated robot. These internationalized scripts can, however, also directly be exported to Lego Mindstorms robots. It also has a component architecture UObject for distributed computation. Unlike the other languages for the NXT the code isn't compiled to a binary file. This method of execution is significantly slower than executing compiled code directly.
