What is the Programmable Brick?

In the Programmable Brick project, we are creating small computers that connect to the real world through various sensors and actuators. Our Programmable Bricks are designed especially for use by kids. They can be used in robot-design activities, data-gathering experiments, and "ubiquitous computing" projects (in which computational power is embedded in everyday objects).

The Programmable Bricks have been developed at the MIT Media Laboratory by Fred Martin, Randy Sargent, and Brian Silverman, with the guidance of Professors Seymour Papert and Mitchel Resnick and support from the LEGO Group and the National Science Foundation.

The Programmable Brick is part of the ongoing LEGO/Logo research project at the Epistemology and Learning Group at the MIT Media Laboratory. About 40 Programmable Bricks are currently in use at school sites and other locations.

Versions of the Programmable Brick

We have developed various Programmable Bricks and Brick-like technologies over the last ten years, including both hardware and software systems. Some of the technology was developed specifically for use with children (e.g., the 6502 Programmable Brick, the Pocket Brick, and the Model 120 Brick), while other technology was developed with university-level applications in mind (e.g., the Mini Board and the 6.270 board).

Here is a brief overview of the collection of Programmable Brick technology, including dates of development and use.

Programmable Brick Documentation

There are several on-line documents:

Brief introduction to Brick project. Discusses two different Brick models. [ ]
Manual for the Programmable Brick Model 120. Print on a PostScript printer. [ ]
11-page overview of the Brick Logo language, excerpted from the above manual. [ ]
13-page document describing how to build sensors for Programmable Bricks.

Please contact Florence Williams ( if you do not have access to FTP and a PostScript printer (required to print out these materials).

How Do I Get a Programmable Brick?

At this stage, the Programmable Brick is not a commercial technology. We are a research group and it is not our charter to sell and support hardware. Therefore, we are using the Programmable Brick technology only with our close research collaborators.

Research Papers About the Programmable Brick

The Programmable Brick project began at the MIT Media Laboratory in 1986. The project builds on a foundation of earlier MIT research on children and technology.

Here is a chronological bibliography of Programmable Brick-related research. An asterisk (*) preceding the reference indicates a document that can be ordered from our publications office. Contact Florence Williams ( for information, or look on our electronic document distribution site
