Why Use Abstraction
- Makes it easier to reason about complex programs by reducing the detail you have to think about at one time
- Makes is easier to test programs - we can test small part individually
- Makes the code is reusable saving time. We can more easily takes code from one program and use it somewhere else.
- Makes code more reliable by allowing us to use the same code over and over.
Code Outline
- Code based on FTC_Motor_Encoders_20200304
- Enhance the drive forward with encoders using the setVelocity to drive the robot in a square.
public class DriveInASquare extends LinearOpMode { @Override public void runOpMode() throws InterruptedException { double TARGET_DISTANCE = 300; // mm (about 12 inches) double MAX_MOTOR_VELOCITY = 600; // mm / second double TARGET_VELOCITY = MAX_MOTOR_VELOCITY / 4; double TARGET_TURN = 90; // degrees int SQUARE_SIDES = 4; waitForStart(); int count = 0; while (opModeIsActive() && count < SQUARE_SIDES) { driveForMmAt (TARGET_DISTANCE, TARGET_VELOCITY); turnForDegrees (TARGET_TURN); count++; } } void driveForMmAt (double distanceMm, double velocityMmPerSec) { } void turnForDegrees (double turnDegrees) { } }

- Exercise 1: The turn method is not completed. Your job is to complete it. The challenges are
- Computing the clicks for each wheel for a differential drive robot.
- Compensating for wheel slippage.
