8 Introduction The heart of the system is the NXT brick, an autonomous LEGO microprocessor that can be programmed using a PC. Designers create a program with easy-to-use, yet featurerich software. Inspire Teach Excite Challenge 8

9 Introduction Downloading programs to an application is easy. Users with Bluetooth -enabled computer hardware can transfer their programs to the NXT wirelessly, or anyone can use the included USB cable to connect their computer to the NXT for program transfer. The robot then takes on a life of its own, fully autonomous from the computer. Inspire Teach Excite Challenge 9

10 The Brain Inspire Teach Excite Challenge 10

11 The Brain This image of the NXT Brain depicts two series of holes These are designed to allow the user to create a cradle for the brain. The standard pegs that come in your NXT kit will fit snugly into these holes. Inspire Teach Excite Challenge 11

Motor receives its information from the brain of the robot.

12 Motor Motors are a combination of three items: 1. An electric motor. 2. A position sensing device. 3. A feedback circuit to control the motor. Motor receives its information from the brain of the robot. Communication between the motor and the brain is transmitted through an NXT cable. Inspire Teach Excite Challenge 12
