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.

Config Generation

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

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

import edu.wpi.first.math.util.Units;


SwerveDrive swerveDrive=new SwerveParser(new File(Filesystem.getDeployDirectory(),"swerve")).createSwerveDrive(Units.feetToMeters(14.5));

1. Delete wheelDiamter, gearRatio, encoderPulsePerRotation from physicalproperties.json
2. Add optimalVoltage to physicalproperties.json
3. Delete maxSpeed and optimalVoltage from swervedrive.json
4. IF a swerve module doesn't have the same drive motor or steering motor as the rest of the swerve drive you MUST specify a conversionFactor for BOTH the drive and steering motor in the modules configuration JSON file. IF one of the motors is the same as the rest of the swerve drive and you want to use that conversionFactor, set the conversionFactor in the module JSON configuration to 0.
5. You MUST specify the maximum speed when creating a SwerveDrive through new SwerveParser(directory).createSwerveDrive(maximumSpeed);
6. IF you do not want to set conversionFactor in swervedrive.json. You can pass it into the constructor as a parameter like this

double DriveConversionFactor = SwerveMath.calculateMetersPerRotation(Units.inchesToMeters(WHEEL_DIAMETER), GEAR_RATIO, ENCODER_RESOLUTION);
double SteeringConversionFactor = SwerveMath.calculateDegreesPerSteeringRotation(GEAR_RATIO, ENCODER_RESOLUTION);
SwerveDrive swerveDrive = new SwerveParser(directory).createSwerveDrive(maximumSpeed, SteeringConversionFactor, DriveConversionFactor);

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

• Invert the angle motor.

• Implement momentum velocity limitations in SwerveMath.
