Programming Mindstorms EV3 and Algorithms

Programming Mindstorms EV3

• Programming Mindstorms EV3 involves creating instructions for a robot to perform tasks.
• This involves writing, testing, debugging, and maintaining code in programming languages.
• The EV3 system uses a block-based coding environment similar to Scratch. This makes it accessible for beginners.

Algorithms

• An algorithm is a detailed step-by-step set of instructions for solving a problem or completing a task.
• Flowcharts graphically represent algorithms using shapes like ovals, parallelograms, squares, and diamonds.
• Pseudocode offers an informal way to represent algorithms in a narrative format.

Flowcharts

• Flowcharts use graphical symbols to represent steps in a process.
• Shapes like ovals (start/end), parallelograms (input/output), and diamonds (decisions) are used.

Pseudocode

• An example shows user input for a program's characteristics followed by a conditional that returns a specific output based on the answer.

Programming

• This is the process of creating a set of instructions (code) for computers to perform tasks.
• Creating instructions involves writing, testing, debugging and updating the code (instructions) using programming languages.

EV3 Classroom

• EV3 Classroom is a programming platform for the LEGO Education Mindstorms EV3 robotics kit.
• It provides a block-based coding environment based on Scratch, making it user-friendly for beginners.
• It helps teach STEM concepts, robotics, and coding.

Blocks Palette

• The EV3 program interface uses a blocks palette to visualize the program instructions.

Blocks

• Blocks are puzzle-like shapes used to create programs.
• They are connected to form a program that runs from top to bottom.
• Connected blocks form a "stack".

Types of Blocks

• Hat Blocks: Begin programs when an event occurs. They belong to the Event category.
• Stack Blocks: These blocks allow stacking other blocks above and below.
• Boolean Blocks: Report boolean values ("true" or "false"). These blocks act as reporters, and are commonly used to check conditions
• Reporter Blocks: These report values from sensors, motors or variable data.
• C Blocks: These blocks allow other blocks to be placed into them. They are part of the control category.
• Cap Blocks: These blocks stop the program's execution or stack.

Block Categories

• The EV3 program environment groups blocks into categories based on functionality. There are over 10 categories including Motors, Movement, Display, Sound, Events, Control, Sensors, Operators, Variables, and My Blocks.

Block Category Details

• Motor Blocks : Control individual EV3 motors, offering both basic motor commands and reporting their current functions
• Movement Blocks: Control two motors at once, typically the base motors in robot vehicles.
• Display Blocks: Control LED lights and the display screen.
• Sound Blocks: Control sound effects generated by the EV3 brick.
• Event Blocks: Initiate programs based on specific events or user inputs.
• Control Blocks: Control the flow of a program (like loops, conditional statements and if-then).
• Sensor Blocks: Read and compare data from sensors.
• Operator Blocks: Perform mathematical operations and string functions to analyze data.
• Variable Blocks: Used to store and manage data within the program.
• My Blocks : Custom blocks allowing users to create their own programming instructions.
