Why Use Abstraction
- Makes the program easier to think about
- Makes is easier to test programs - we can test small part individually
- Makes the code easier to user over and over 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.
Move the Robot in a Square Demo Code
Check Points
- Copy the Drive In A Square program to your robot and test it.
- Investigate a simplified outline of the move in a square program to help you understand how to write methods. See FTC Drive In a Square Outline 20230112.
- Modify the program to move forward 18 inches, turn left 90 degrees, and move backward 12 inches.
- Modify the program to work with 4 motors so you can support the Mecanum drivetrain.
Refined Demo Code
TBD: Complete code refinements and integrate into this lab.
Simplified PowerUpMotors to us Ticks for distance and velocity. Add GoForward and GoSideways helper methods
Check Points
- Compute how many Ticks per millimeter the robot move forward.
- Sidesize
- Why are they different
- Find a web reference computer these values based on Mecadum wheels size and motor configuration
- Do the computations and compare with your test results
- Measure how well the moveForward method drove the robot straight
- How does speed and distance impact
