Study Notes

Morse Code

Developed by Samuel Morse in the early 1800s as the first landline telegraph system
Uses two characters: dot (.) and dash (-) as a binary language
Can be communicated via light or sound
A dot is a quick and single sound, while a dash is a prolonged sound

Robotics (NXT)

Two software used: Lego Mindstorms NXT 2.0 and Lego Digital Designer
Lego Mindstorms NXT 2.0 is for programming and coding with a file format of .rbt
Lego Digital Designer is for designing robots with a file format of .lxf

NXT Controller

Record/Play feature allows recording of robot actions and replaying them
Records the number of motor turns and replays the same number of turns
Steps to transfer software files: find Control Configuration and click on the Download icon

NXT Programming Environment

Allows creating and modifying NXT programs and downloading them to the NXT Controller
Connects to the NXT Controller through Bluetooth or USB data cable
Comprises of Work Area, Programming Palettes, Configuration Panel, Help Panel, Navigation Panel, and Control Configuration Panel

Programming Environment Components

Work Area (Program Sheet): center of the screen for placing programming objects
Programming Palettes: left of the Work Area with blocks to create a program
Configuration Panel: bottom-left for configuring program blocks
Help Panel: bottom-right for showing block descriptions
Navigation Panel: selects which part of the program to display in the Work Area
Control Configuration Panel: sets the connection between software and NXT Controller

Test your knowledge on Morse Code, the binary language developed by Samuel Morse, and explore two software used in Robotics - Lego Mindstorms NXT 2.0 for programming/coding and Lego Digital Designer for designing robots.
