This is the code for a Lego Mindstorms NXT 2.0 scorpion. The code is very simple. I was only interested in the sting mechanism so this is the only behaviour this program implements (it has no legs).

You will see examples of several of the NXT-G programming techniques in action including Loops, Switches, Data Wires, Sequence Beams, Logic/Range/Compare, Math, and Variables. The more complex programs use many or all of these, so start with the easy ones and work your way up.

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. The manual controls could be used to independently control the three motors.
