LiveWindow.updateValues() is now called from IterativeRobotBase on every
loop iteration. Telemetry for all WPILib classes is enabled by default;
it can be disabled for specific classes using LiveWindow.disableTelemetry(),
or all telemetry can be disabled using LiveWindow.disableAllTelemetry().
This necessitated changing the hook methodology into other classes to
be more property-based rather than each class providing multiple functions.
This had the benefit of reducing boilerplate and increasing consistency.
- Remove NamedSendable, add name to Sendable.
- Provide SendableBase abstract class.
- Deprecate LiveWindow addSensor/addActuator interfaces.
- Add LiveWindow support to drive classes.
- Add addChild() helper functions to Subsystem.
- Fix inheritance hierarchy. Now only sensors inherit from SensorBase.
Other devices inherit from some combination of SendableBase, ErrorBase, or
nothing.
I also found some inconsistencies in MecanumDrive and KilloughDrive and fixed
them.
Drive now uses the NED axes convention. Therefore, the positive X axis points
ahead, the positive Y axis points to the right, and the positive Z axis points
down.
Translation in X assumes forward is positive. Translation in Y assumes right is
positive. Rotation rate assumes clockwise is positive. Angles are measured
clockwise from the positive X axis.
Based on the angle origin convention, DrivePolar() for both Mecanum and Killough
needed the normalization removed, sine used to compute the Y component, and
cosine used to compute the X component.
The vector rotation done in DriveCartesian() needs to rotate by a negative angle
instead of positive to undo the robot's rotation. RobotDrive assumed a clockwise
angle and sensors returned counter-clockwise angles, which is why it used a
positive angle for rotation.
