Unit 1

Programming Concepts

• Computer Coordinate System
• Definition: A system with an X and Y axis. X is horizontal and Y is vertical.
• Examples: In TouchDevelop, setting the robot's position with robot -> set pos(100, 350).
• Conditionals
• Definition: Makes descisions based on whether something is true or false.
• Examples: An if statement.
• Events
• Definition: Things that happen outside the program.
• Examples: Clicking a mouse or keyboard button.
• Functions
• Definition: Makes things happen to objects.
• Examples: game -> set life(3) in TouchDevelop.
• Parameters
• Definition: Pieces of information given to functions.
• Examples: The colour that you give in set colour()
• Loop
• Definition: A block of code that can be run multiple times in a row.
• Examples: A for or while loop.
• Objects
• Definition: Things you can do stuff with. "Nouns" of programming.
• Examples: The game and/or board.
• Properties
• Definition: Details of objects.
• Examples: X, Y, width, height, colour.
• Syntax
• Definition: The grammar of the code. Slightly different for each language.
• Examples: In Java, if(true) thing.do(something); is correct but If(True) thing->do(something) isn't
• Variables
• Definition: A single value.
• Examples: A number or a character.
• Components
• Definition: The different parts that make up a computer program.
• Examples:
• Behaviour
• Definition: The way that programs do things.
• Examples: A temperature converter's behaviour is different from a video game's.
• Event Handlers
• Definition: Objects that register and process events.
• Examples: A KeyListener or MouseListener
• Event Types
• Definition: The different types of events that can be detected.
• Examples: A KeyEvent or MouseEvent
• App Inventor Conditional Blocks
• Definition: Makes descisions based on whether or not something is true.
• Examples: Similar to an if statement.
• App Inventor Repeat Blocks
• Definition: Repeats code a set number of times.
• Examples: Similar to a loop.
• Variables vs. Persistant Data
• Definition: Variables are local values that can be used in one part of the program. Persistant data is independant of the program.
• Examples: An integer in JavaScript and a value stored in a SQL database.

What I Did for Robotics

During week 2, I worked on some robotics code. I worked on the following:

List of Tasks Completed

• A turnLeft(int degrees) and turnRight(int degrees) method for the robot
• Fixing the drive train
• Creating a drive(double inches, double speed) method for the robot
• Moving code to the new laptop
• Re-working the ball unloading system
• Creating and testing basic autonomous code
