Here are some ideas and tricks for using the NXT along with other LEGO parts that do not come with the LEGO MINDSTORMS NXT set. Spik3r This six-legged creature doesn’t just look like a scorpion, it also acts like one. It turns sharply, snaps with it’s crushing claw, and it’s lightning tail is ready to fire at anyone or anything that gets in its way.

Robot based on the NXT platform Subject Availability 1998 ( 1998)– Lego Mindstorms is a hardware software platform produced by for the development of programmable robots based on. Each version of the system includes an intelligent brick computer that controls the system, a set of modular sensors and motors, and parts from the line to create the mechanical systems. Since creation, there have been four generations of the Mindstorms platform: the original Robotics Invention System, NXT, NXT 2.0, and EV3. With each platform release, the motor and sensor capabilities expanded. The latest system,, was released on September 1, 2013. Some robot competitions use this set, such as the and the.

A second prototype series was developed in the mid-1990s before the final device was released in 1998. The first visual programming environment was called LEGOsheets, since it was created by the in 1994 based on. Mindstorms is named after the book.

Pre-Mindstorm [ ] Before Mindstorms, Lego had previously done some experimentation with robotic sets. One of the main foundations of these sets was the Lego Technic system and its 4.5V and later 9V system for electrical peripherals that had been evolving through the 1980s. Computer Interfaces [ ] One of the first examples of programmable Lego was the LEGO Interface-A adapter, used for the educational-only Lego Dacta TC-Logo system. These sets from the mid-late 80's provided a dedicated hardware interface to control the Lego Technic 4.5V system using a computer, and for the first time it introduced electric Lego sensors. This interface was controlled from an IBM-PC or Apple-IIe by the use of a special version of, a simple programming language designed for use in children's education. In the mid-90's, the Lego Dacta Control Lab released as a follow-up for Lego 9V system, using a standard serial port rather than a custom hardware interface card.

This move also introduced new 9V sensors, which would later become a key component for the first-generation Mindstorms sets. It is worth noting that the Control Lab had dedicated ports for active and passive sensors, while later products like first generation Midstorms provided support for both kinds on the same ports. Technic Control Center [ ] The control center (1990) was the first programmable standalone Lego product, in the sense of being able to store sequence-based programs and run them. It featured three output ports and manual control, and it was only capable of storing linear sequences of manual input plus timing information. It could store up to two programs at once.

To record a program; the controller had to be put in programming mode, and then any manual control would be recorded to the program. Pauses could also be included in a program. When the recording was done, the controller could successfully recall and execute any manual action done during the recording. The executing program could be set to loop infinitely.

Cybermaster [ ]. Lego Cybermaster Cybermaster was mainly sold in Europe and Australia/New Zealand and was available for a short time in the United States via the Lego Club magazines. It was aimed at an older audience as an early attempt of merging with robotics and Lego. The brick shares many, especially software, features with the RCX but differs in appearance and technical specifications: one output (plus two built-in) and four sensors. • It uses (27 MHz R/C band) instead of IR for communication.

• It has two built-in motors with integrated. • It is limited to passive sensors (a simple with internal pull-up resistors). • The sensors shipped with it are color-coded and have internal resistors in their open state (allowing the Pbrick to sense which sensor is attached to which port).

• It has a fixed firmware (so it cannot be upgraded or replaced). • It has limited RAM for programs (395 bytes) [ ] and only one program slot. Despite its obvious limitations it has a number of advantages over its 'big brother', the RCX. • The RF link has greater range and is omnidirectional. • The built-in tachometer and speedometer sensors on the internal motors provides the same function as the external rotation sensor to the RCX, but without using up sensor ports. This makes it very useful for various mobile platforms and performing advanced motion/positioning tasks.
