The field image and robot image can be loaded or just a wireframe used.
The robot can be moved and rotated with a mouse click + drag.
The robot position is settable in robot code via the Field2d class.
This PR changes the spline parameterizer to use an explicit stack instead of recursion. This is motivated by the fact that splines with adjacent waypoints with approximately opposite headings will never parameterize. In this case the parameterizer subdivides these malformed splines fine for a while, and then gets stuck parameterizing infinitely on some interval. In the recursive approach, this would lead to a stack overflow. We could implement a recursion depth counter (this is what my team did on our similar trajectory code last season), but it's hard to choose a good number for max depth because the initial amount of stack used varies based on how the user calls Parameterize.
A good solution for this is converting the recursion to an "explicit stack," which basically simulates recursion, but allows us to have a much larger maximum stack size. Because we avoid the stack overflow, we can instead throws a more informative MalformedSplineException. If the user is using the TrajectoryGenerator instead of the SplineParameterizer directly then the TrajectoryGenerator will go ahead and catch the exception, return a harmless empty trajectory, and report and error to the driver station.
Add a Sendable* overload so pointers to sendable objects work appropriately.
Otherwise an AddLW(this) in a child (which is a Sendable*) could be a
different pointer than a void* to the same object.
For example:
AnalogInput constructor calls AddLW(this)
AnalogPotentiometer constructor calls AddChild(analog input pointer)
Also add handling for the child object moving (if it's Sendable).
- new CommandScheduler
- kinematics and odometry classes
- new PIDController
- ProfiledPIDController
- TrapezoidProfile (reported in Constraints class)
Also update instances.txt to match latest NI version.
One side effect is that a couple of classes are no longer constexpr.
It doesn't make sense to continue to provide a less accurate method of performing odometry
when a more accurate method using distances exists.
This also removes the need to pass DifferentialDriveKinematics to the constructor.
The odometry classes previously took in the robot angle as an argument, meaning that users had to take care of offsetting the gyro themselves to accurately report the robot angle. This change will make it so that users will not have to worry about resetting gyros and adding offsets themselves, as this will be handled by the odometry classes.
This is useful for both cleanly exiting from simulation and for unit testing
at a framework level.
This change required removing move constructor/assignment from IterativeRobot.
