This document provides an overview of the names and quantities of components included in the LEGO Mindstorms Robotics System. It is organized by compartments that contain different types of pieces like connectors, beams, gears, axles and specialty pieces. Each compartment lists the name and required number of each type of piece. The bottom tray includes smart parts like the NXT brick, battery, motors and sensors. This ensures builders have all necessary pieces to construct robots using the LEGO Mindstorms system.
