Toy-maker Lego is introducing programmable bricks that can be used to control robots and other machines built using these blocks. Programs for the new RCX brick can be created on a personal computer using a special software and then downloaded into the brick. Each RCX unit works with built-in sensors and motors that will be included in the Mindworks Lego set to be introduced to the markets soon. The Massachusetts Institute of Technology, USA, helped Lego develop the bricks and the software.
