Concept
Lego Mindstorms (sometimes stylized as LEGO MINDSTORMS) is a discontinued hardware and software structure which develops programmable robots based on Lego building blocks. Each version includes an intelligent brick (or hub), a set of modular sensors and motors, and parts from the Lego Technic line to create the mechanical systems. The system is controlled by the intelligent brick, which act as the brain of the mechanical system. While originally conceptualized and launched as a tool to support educational constructivism, Mindstorms has become the first home robotics kit available to a wide audience. It has developed a community of adult hobbyists and hackers as well as students and general Lego enthusiasts following the product's launch in 1998. In October 2022, The Lego Group announced Lego Mindstorms will be discontinued at the end of 2022. In 1985, Seymour Papert, Mitchel Resnick and Stephen Ocko created a company called Microworlds with the intent of developing a construction kit that could be animated by computers for educational purposes. Papert had previously created the Logo programming language as a tool to "support the development of new ways of thinking and learning", and employed "Turtle" robots to physically act out the programs in the real world. As the types of programs created were limited by the shape of the Turtle, the idea came up to make a construction kit that could use Logo commands to animate a creation of the learner's own design. Similar to the "floor turtle" robots used to demonstrate Logo commands in the real world, a construction system that ran Logo commands would also demonstrate them in the real world, but allowing the child to construct their own creations benefitted the learning experience by putting them in control In considering which construction system to partner with, they wanted a "low floor high ceiling" approach, something that was easy to pick up but very powerful. To this end, they decided to use Lego bricks due to the system and diversity of pieces, and the Logo language due to the groups familiarity with the software and its ease of use.
