Introduction

The Lego Mindstorms Robotics Invention System (RIS)  combines familiar Lego bricks with some more specialized pieces such as wheels and gears, together with a small computer. The computer, known as the RCX, runs on batteries and can receive small programs from a personal computer. Using these programs the RCX can detect and evaluate readings from touch sensors and light sensors. The RCX can also power and control small motors which can drive wheels or robotic arms.

The Mindstorms software, Robolab, allows users to create programs on the RCX which control the robot’s motion and allow it to react to certain conditions in its environment. The RIS provides children and adults with the ability to design and create concrete objects which are operated by programs which are created through a more abstract process.

The Lego Robotics system was developed by a number of researchers who were exploring the way children learn and how technology and physical construction activities could enhance that learning process. Seymour Papert and Mitchell Resnick were instrumental in the development of the Lego Robotics system at the MIT Media Lab. They believe that the educational value of that programmable construction system, and similar technologies, lie in their ability to allow learners to design their own learning. Resnick states, "Like Papert, we believe that the best learning experiences, for most people, come when they are actively engaged in designing and creating things, especially things that are meaningful to them or others around them." (Resnick and Silverman, 2005) Resnick believes that employing Lego Robotics in an educational setting allows learners to design learning activities that allow them to acquire knowledge rather than information.

There are a number of challenges encountered when trying to incorporate Lego Robotics into a curriculum. The teachers need training to understand the technology and the quirks of building with Legos. (Martin 2000) There needs to be computers available (computers which operate properly and are maintained), and of course adequate time. Overall the resources necessary are far from trivial, and some might argue that they should be directed to other subject areas or activities. (Cuban 2001)

This web site will document several aspects of the use of Lego Robotics in schools, including the development of the system, the theoretical design of the tool, the history of adoption by educators, the challenges of incorporating Lego Robotics in the classroom, and the most recent developments concerning the system.
