NXT 需要 6 顆 AA 電池。 Alkaline batteries are recommended. Rechargeable batteries can be used, but the ‘NXT’s power may be reduced, e.g. the motors turn more slowly.

7. Note that ALL the 6-wire cables can be used in both input and output ports, sensors and motors, but to work sensors HAVE to be attached to the input ports (1-4) and motors HAVE to be attached to the output ports (A-C). A special hybrid cable is used existing motors, lamps and sensors. Connecting motors, lamps and sensors to the NXT The NXT – detailed specification 1.Make sure that your NXT is turned on. 2.Push the reset button that is located on the back of your NXT in the LEGO® Technic hole in the upper left corner.

27. NXT and FLL/WRO Will the FLL Challenge change because of the new product? The FLL Challenge will be designed to support both the existing and new LEGO MINDSTORMS technology and we anticipate no game- related advantage or disadvantage to using either. FLL is in the process of evaluating a migration plan to introduce the new technology into FLL Challenges in future years. If I register for FLL, will I receive the product before August? No, the new product is expected to be available for shipment no earlier than August, 2006 in the US and Canada and in September for other countries. Teams will have the option to purchase the existing technology, which will ship when registration orders begin filling in June.

39. The Touch Sensor gives your robot a sense of touch. The Touch Sensor detects when it is being pressed by something and when it is released again. Suggestions for use You can use the Touch Sensor to make your robot pick up things: a robotic arm equipped with a Touch Sensor lets the robot know whether or not there is something in its grabber arm to grab. Or you can use a Touch Sensor to make your robot act on a command. For example, by pressing the Touch Sensor you can make your robot walk, talk, close a door, or turn on your TV. Touch Sensor The NXT sensors – detailed specification

40. 碰觸感測器能夠感受到物體的擠壓、施放 和撞擊。 使用建議 機器人可以使用碰觸感測器來抓取物體。 安裝了碰觸感測器的機器手能夠知道是否 有物體需要抓取。你也可以使用碰觸感測 器來讓機器人行走、說話、關門、甚至打 開電視。

41. Light Sensor This is what your eyes see. This is what your robot will see, using the light sensor. The NXT sensors – detailed specification Reads light intensity from environment Reads reflection from IR emitter

42. 光線感測器是機器人的兩種視覺感測器之一（另 一個是超音波感測器）。 光線感測器能夠讓機器人分辯光線的強弱。它能 夠感受房間的光線強度和根據顏色來測量光線強 度。 下圖是人看到的和機器人看到的。

43. The Ultrasonic Sensor is the other sensor that gives your robot vision. The Ultrasonic Sensor enables the robot to see and detect objects. You can also use it to make your robot avoid obstacles, sense and measure distance, and detect movement. The Ultrasonic Sensor uses the same scientific principle as bats: it measures distance by calculating the time it takes for a sound wave to hit an object and return – just like an echo. The Ultrasonic Sensor measures distance in centimeters and in inches on the NXT. It is able to measure distances from 0 to 255 centimeters with a precision of +/-3 cm. Large-sized objects with hard surfaces return the best readings. Objects made of soft fabric or that are curved (like a ball) or are very thin or small can be difficult for the sensor to detect. Note that two or more Ultrasonic Sensors operating in the same room may interrupt each other’s readings. Ultra sonic Sensor The NXT sensors – detailed specification Back to overview

44. 超音波感測器是機器人的兩個視覺傳感器之 一（另一個是光線感測器）。超音波感測器 能夠讓機器人看見和檢測到物體。你可以使 用它來防止機器人碰到障礙物，測量距離， 檢測移動。 超音波感測器檢測距離的單位可以是厘米或 者英吋。它可以檢測的距離從 0 到 255 里米 ，精度是正負 3 厘米。

45. 超音波感測器使用的技術和蝙蝠很像。它通 過計算聲音返回使用的時間來計算距離。大 的表面堅硬的物體是最容易辨認的。軟織物 、表面彎曲的物體（比如球）或者很薄、很 小的物體比較難辨認。 注意：在同一個房間裡面的兩個或多個超音 波感測器可能會互相影響。

46. The Sound Sensor can detect both decibels (dB) and adjusted decibels (dBA). A decibel is a measurement of sound pressure. dBA: In detecting adjusted decibels, the sensitivity of the sensor is adapted to the sensitivity of the human ear. In other words, these are sounds that your ears are able to hear. dB: In detecting standard (unadjusted) decibels, all sounds are measured with equal sensitivity. Thus, these sounds may include some that are too high or low for the human ear to hear. The Sound Sensor can measure sound pressure levels up to 90 dB – about the level of a lawnmower. Sound pressure levels are extremely complicated, so the Sound Sensor readings on the MINDSTORMS® NXT are displayed in percent (%). To give some comparative examples: 4-5% is like a silent living room. 5-10% would be the reading you get from someone talking some distance away. 10-30 % is normal conversation close to the sensor or music played at a normal level. And you will record readings of 30-100% from people shouting and music played at high volumes. Sound Sensor The NXT sensors – detailed specification Back to overview

47. 聲音感測器能夠檢測到分貝（ decibels [dB] ）和調 整分貝（ adjusted decibel [dBA]) 調整分貝是一種衡量聲音壓力的度量方法。 調整分貝（ dBA ） : 當檢測調整分貝時，感測器能 夠感受人感受的聲音。或者說，它能聽到人可以 聽到的聲音。 分貝（ dB ） : 當檢測分貝時，所有的聲音都可以 被檢測到，包括對人耳來說過高頻和過低頻的聲 音。

48. 聲音感測器能夠檢測到的聲壓大於 90 分貝。因為 聲壓的等級非常複雜，所以在 Mindstorms NXT 上 顯示的時比例 (%). 數字越小，聲音越小。例如： ‧ 4-5% 大約是安靜的臥室 ‧ 5-10% 從較遠距離聽人的談話 ‧ 10-30% 較近距離的正常談話，或者正常音量下 的聲音播放器 ‧ 30-100% 人們的喊叫聲，或者大音量的音響
