What kind of sensors come with the MINDSTORMS NXT? 1 Ultrasonic Sensor: makes the robots ‘see’, it can measure distance, movements and detects objects. 2 Touch Sensors: make the robots ‘feel’, reacting to touch or release. 1 Color Sensor: The Color Sensor is a three-in-one sensor; It acts as a Color Sensor, accurately distinguishing between different colors, it acts as Light Sensor, detecting light settings, both ambient light and light intensities from surfaces, and also works as a Color Lamp, shining bright red, green or blue. Additional sensors and accessories are available from our online shop. How many motors come in the set? 3 Interactive Servo Motors with built-in Rotation Sensors for precise control of your robot’s movement. What is a servo motor? An electric motor whose speed or position is controlled by a closed loop feedback circuit that can sense its position. The speed of the motor is measured by a tachometer. The tachometer produces a voltage that is proportional to the speed. This voltage is compared to a reference point and the difference, or error, is used to adjust the speed of the motor, either up or down. What kind of software does the set come with? The LEGO MINDSTORMS NXT 2.0 comes with an intuitive easy-to-use programming software. It has PC and Mac compatible software interface, powered by LabVIEW from National Instruments. It has an intuitive, icon-based drag-and-drop environment for "building" programs by connecting command blocks. Also, it includes 16 fun and action-packed robot challenges with step-by-step building instructions to introduce beginners to the process of building and programming their very own robots. Is there any difference in the NXT micro-controller coming with the NXT 2.0? No. It is the same 32-bit micro-controller with 256 KB memory as in the NXT 1.0 set (#8527). There is no Light Sensor in the set – will it still be available? Yes. Though the new Color Sensor compliments the functionality of the old Light Sensor, our online shop will still be selling the Light Sensor. There is no Sound Sensor in the set – will it still be available? Yes. You can purchase the Sound Sensor through our online shop. Can advanced users program the NXT with other programming languages and applications? NXT FAQ – v .02 - 21012009 Yes. Since the NXT generation was launched in 2006 a big collection of languages and applications has been adapted to work with the NXT, mostly developed by hardcore users in the global MINDSTORMS community. Notably, the NXT can also be programmed with LabVIEW, the high-end programming environment on which the NXT programming language is based. To create programs for the NXT using LabVIEW you can download the free LabVIEW Toolkit for LEGO® MINDSTORMS® NXT via the National Instruments website: http://www.ni.com/academic/mindstorms/ Read more about alternative programming languages on www.legomindstorms.com What is the NXT Intelligent Brick? The “brain” of the robot: an intelligent, computer-controlled LEGO brick which makes the robot come alive and perform different operations. What is Bluetooth? Bluetooth is a technical industry standard of short-range radio technology that facilitates communication between wireless devices such as mobile phones, PDAs (personal digital assistants) and handheld computers, and wireless enabled laptop or desktop computers and peripherals. Once the connection between two devices is established (and approved), no third device can interfere. How do you download programs to the NXT Intelligent Brick? Downloading programs to an invention is easy. Anyone can use the included USB 2.0 cable to connect their computer to the NXT for program transfer. Users with Bluetooth®-enabled computer hardware can transfer their programs to the NXT wirelessly. Once a program is downloaded the robot then takes on a life of its own, fully autonomous from the computer. The inclusion of Bluetooth technology also extends possibilities for controlling robots remotely, for example, from a mobile phone or PDA. How far can Bluetooth in the NXT brick reach? Up to 10 meters as a minimum, but it is very likely to have longer reach. The NXT uses a Class II Bluetooth radio, this means you can communicate wirelessly up to 10 meters.
