MIT Yellow Brick Logo (MIT-YBL) is an implementation of the Logo language for the LEGO RCX Brick. MIT Yellow Brick Logo includes:

MIT Logo Blocks (MIT-LB) is a graphical version of MIT Yellow Brick Logo. Presently, MIT-LB is only available for the Macintosh.



MIT Yellow Brick Logo and MIT Logo Blocks are intended to be used by educators in a classroom or workshop format.

It is important that MIT-YBL and MIT-LB be used under the supervision of those who have a significant background in the use of the Logo language with children. Therefore, we have established the following requirements for the use of MIT-YBL and MIT-LB. You must either:

  1. Have five (5) years experience using Logo environments with children. (Examples of Logo environments include: LEGO tc logo, LEGO Control Lab, LCSI LogoWriter, and LSCI MicroWorlds.)

  2. Or, participate in a week-long intensive workshop in which MIT-YBL and MIT-LB are used.

If you do not fit into either of these categories, but believe you should be qualified to use MIT-YBL and MIT-LB, please contact us at
