Yet Another Generic Swerve Library (YAGSL) Example project

YAGSL is intended to be an easy implementation of a generic swerve drive that should work for most square swerve drives. The project is documented on here. The JSON documentation can also be found here

This example is intended to be a starting place on how to use YAGSL. By no means is this intended to be the base of your robot project. YAGSL provides an easy way to generate a SwerveDrive which can be used in both TimedRobot and Command-Based Robot templates.

Overview

Config Generation

Create an issue if there is any errors you find!

We will be actively montoring this and fix any issues when we can!

Development

• Development happens here on YAGSL-Example. YAGSL and YAGSL-Lib are updated on a nightly basis.

TL;DR Generate and download your configuration here and unzip it so that it follows structure below:

deploy
└── swerve
    ├── controllerproperties.json
    ├── modules
    │   ├── backleft.json
    │   ├── backright.json
    │   ├── frontleft.json
    │   ├── frontright.json
    │   ├── physicalproperties.json
    │   └── pidfproperties.json
    └── swervedrive.json

Then create your SwerveDrive object like this.

import java.io.File;
import edu.wpi.first.wpilibj.Filesystem;
import swervelib.parser.SwerveParser;
import swervelib.SwerveDrive;

File swerveJsonDirectory=new File(Filesystem.getDeployDirectory(),"swerve");
    SwerveDrive swerveDrive=new SwerveParser(swerveJsonDirectory).createSwerveDrive();

Falcon Support would not have been possible without support from Team 1466 Webb Robotics!

Configuration Tips

My Robot Spins around uncontrollably during autonomous or when attempting to set the heading!

• Invert the gyro scope.
• Invert the drive motors for every module. (If front and back become reversed when turning)

Angle motors are erratic.

• Invert the angle motor.

My robot is heavy.

• Implement momentum velocity limitations in SwerveMath.

Ensure the IMU is centered on the robot
