For those of you who love to program here are the top 10 programming languages for jobs. Lets see how many you can learn! :)
The Samantha Module
The Samantha module is a device which gives teams ability to control their robot remotely, through a wireless connection. The module is connected to the NXT through a USB cable. The Samantha module causes it to start and stop the robot remotely. All of these functions are proceed by the NXT microcomputer.
The IR Beacon
The IR beacon is made by HiTechnic. It is powered by a 9V battery and is has 2 status LEDs and 3 IR LEDs. The light from the IR LEDs is not visible by the naked eye but it is able to be read by the IR seeker sensor.
The Seeker Sensor
The IR seeker sensor is also created by HiTechnic it is used to detect and travel towards and infrared source of energy such as the IR beacon. It detects un-modulated (DC) and modulated (AC) IR signals. During the AC mode it would detect signals at 1200 or 600 Hz. For the FTC competition the IR beacons pulse at 1200 Hz.
The Lego mindstorm NXT is a microcomputer which is considered the “brain” of the robot. It lets the servos and motors connected to it come alive.
