| - | ===== Elements' description ===== | ||
| - | ==== NXT Brick ==== | ||
| - | |||
| - | NXT Brick is hearth of Mindstorms robot. | ||
| - | Because of it, the communication with robot, programming and controlling is possible. | ||
| - | |||
| - | === NXT Brick elements === | ||
| - | * 32-bit ARM7 Mikrocontroler | ||
| - | * 256 Kb FLASH, 64 Kb RAM | ||
| - | * 8-bit AVR Microcontroller | ||
| - | * 4 Kb FLASH, 512 B RAM | ||
| - | * Servomotors' ports: A, B, C | ||
| - | * Sensors' ports: 1, 2, 3, 4 | ||
| - | * USB port (12 Mbit/s) | ||
| - | * 8 kHz speaker, 8-bit channel, sample rate 2-16 KHz | ||
| - | * Buttons (menu service) | ||
| - | * LCD display, 100 x 64 px | ||
| - | * Bluetooth wireless communication (Bluetooth Class II V2.0 compliant) | ||
| - | * 6 AA batteries | ||

| - | |||
| - | === Communication with Brick === | ||
| - | |||
| - | Communication with Brick is possible with: | ||
| - | |||
| - | * USB | ||
| - | * Bluetooth | ||
| - | |||
| - | With both methods it's possible to: | ||
| - | * load Brick programs | ||
| - | * download data (eg. data collected by robot) from Brick | ||

| - | |||
| - | ==== Servomotors ==== | ||
| - | |||
| - | In each kit there are 3 servomotors: | ||
| - | * useful to control revs | ||
| - | * with revenue sensors, useful to precise tracking of propeller shaft position | ||

| - | |||
| - | ==== Sensors ==== | ||
| - | |||
| - | === Sound sensor === | ||
| - | * microphone with possibility of sound intensity measurement | ||
| - | * returns sound intensity in [dB] and in [dBA] | ||
| - | * range to 90 dB | ||
| - | * percentage scale of sound intensity | ||
| - | |||
| - | == Links == | ||
| - | * http://mindstorms.lego.com/Overview/Sound_Sensor.aspx | ||
| - | |||
| - | === Ultrasonic sensor === | ||
| - | It can be used to: | ||
| - | * measure distance from barrier (cm and inches) | ||
| - | * detect objects | ||
| - | * detect movement | ||
| - | |||
| - | Range: 0-255 cm, precision +/- 3 cm. | ||
| - | |||
| - | How it works?: | ||
| - | Distance is calculated on the basis of time of sound wave return to robot after barrier bounce. (The same rule is used by bats and submarines.) | ||
| - | |||
| - | Notices: | ||
| - | * If there are more then 1 ultrasonic sensor in the same room, there can exist some interferences and the sensor can work not correct. | ||
| - | * Curved surfaces (eg. spheres) are difficult to detect. | ||

| - | |||
| - | === Touch sensor === | ||
| - | * detects toutches with the orange button | ||
| - | * can differentiate 3 states of touch: | ||
| - | * pressed | ||
| - | * bumped | ||
| - | * released | ||
| - | * additional: 3 buttons on NXT Brick (left, right, center) can be set as touch detectors | ||

| - | |||
| - | |||
| - | === Light sensor === | ||
| - | * useful to differentiate lightness and darkness | ||
| - | * returns the light intensity | ||
| - | * measure the light intensity reflected from colorful surfaces (indirect color detection) | ||

| - | |||
| - | |||
| - | ==== Testpad ==== | ||
| - | |||
| - | * Dimensions: 90 cm x 60 cm | ||
| - | * Used to test robots | ||
| - | * Content: | ||
| - | * colorful fields to calibrate color sensor | ||
| - | * area limited by black line to test robots moving inside | ||
| - | * ruler to check indications of distance sensors | ||
| - | * field to analise robot's rotation | ||
