Summer Project

MiniBot — The Course Project

you're building a real WRT-style robot codebase from scratch across 8 weeks. every week adds a new piece. by week 8, you'll have a fully structured robot program.

What You're Building

MiniBot is a simplified version of our actual FRC robot code. it uses the same patterns, naming conventions, and file structure as WaltonRobotics/Rebuilt. when you're done, your code could be the base of a real robot project.

Week-by-Week Checklist

Week	File	What to build	Core concept
Week 1	`Constants.java`	Inner classes `DriveK` + `ShooterK` with motor IDs, speeds, gear ratios	Variables, `final`, naming conventions
Week 2	`AutoLogic.java`	Static method that uses if/switch to return an auto routine name given an input mode int	if/else, switch, booleans
Week 3	`SensorProcessor.java`	Static methods: average of double array, count values above a threshold, find min/max	for loops, arrays, methods
Week 4	`DriveCalculator.java`	Static utility methods: RPM to m/s, ticks to rotations, clamp(val, min, max), deadband(input, threshold)	Static methods, parameters, return types
Week 5	`DriveSubsystem.java`	Class with `private final` motor fields, constructor, `periodic()`, `drive(double speed)`, `stop()`, getters	OOP, encapsulation, constructors
Week 6	`ShooterSubsystem.java`	Extends same abstract base as DriveSubsystem. Adds `m_targetRPS`, `isAtSpeed()`, overrides `periodic()`	Inheritance, `extends`, `@Override`
Week 7	`RobotState.java`	Enum with `IDLE`, `DRIVING`, `SHOOTING`, `DISABLED`. Plus interface `IControllable` with method signatures.	Enums, interfaces, nested classes
Week 8	`Robot.java`	Extends `TimedRobot`. Fields for both subsystems. `configureBindings()`. `robotPeriodic()` with CommandScheduler. Uses `RobotState`.	Full project integration

Submission

at the end of week 8, you'll push all your .java files to a branch in the team repo and open a pull request. the leads will review your code — same process as real contributions to our robot.

Include a short description of what you built and anything you're unsure about. We give feedback, not just grades.

Grading (quick version)

20 pts

Naming conventions

k prefix on constants. m_ prefix on member vars. PascalCase classes. camelCase methods.

20 pts

OOP structure

Subsystems have proper constructors, periodic(), getters/setters. Inheritance and interface used correctly.

20 pts

No magic numbers

Every constant lives in Constants.java. Nothing hardcoded inline — not even CAN IDs.

20 pts

Comments

Every public method has a Javadoc. Tricky logic has inline // comments explaining the why.

20 pts

Compiles + runs

Your code should compile without errors. Logic should be sound — no while loops in periodic(), no raw mutation of private fields from outside the class.
