__post_init__

__post_init__()

Initialize HelixTrajectory.

sample

sample(t: ArrayLike) -> ControllerTarget

Sample the helix at time t.

sample_heading

sample_heading(t: ArrayLike, pos: ArrayLike, vel: ArrayLike, acc: ArrayLike) -> tuple[ArrayLike, ArrayLike]

Sample batched yaw and yaw-rate references for time values t.

build_target

build_target(t: ArrayLike, pos: ArrayLike, vel: ArrayLike, acc: ArrayLike) -> ControllerTarget

Assemble a batched dict target from motion primitives.
