Elements' description
NXT Brick
NXT Brick is the hearth of Mindstorms robot.
Because of it, the communication with robot, programming and controlling is possible.

Communication with Brick
Communication with Brick is possible with:
With both methods it is possible to:

Servomotors
In each kit there are 3 servomotors:

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
Ultrasonic sensor
It can be used to:
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.
Links
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.
Links
Light sensor
useful to differentiate lightness and darkness,
returns the light intensity,
measure the light intensity reflected from colorful surfaces (indirect color detection).
