Toy-maker Lego is introducing programmable bricks that can be used to control
robots and other machines built from the blocks. Programs for the new RCX brick
can be created on a PC using special software and downloaded into the block. The
RCX works with sensors and motors that will be included in the Mindworks Lego
set due to be unveiled in the autumn. The Massachusetts Institute of Technology
helped Lego develop the bricks and the software.
