User's Manual

LEGO® MINDSTORMS™ for Schools uses the ROBOLAB software to write programs. The ROBOLAB software runs on both
PCs and MACs. LEGO MINDSTORMS for Schools includes an RCX—a programmable LEGO brick. The RCX is a microcom-
puter with three output ports A, B and C for connecting motors and lamps, and three input ports 1, 2 and 3 for connecting
sensors. ROBOLAB programs are downloaded to the RCX via an Infrared (IR) Tower. The IR Tower is available with a serial
connection (COM port) or a USB connection (for 2.5 or higher versions only).
