course_loop_bend — DRIVE `course` op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.course_loop_bend(radius=30.0, width=8.0, arc_pts=64) (to call the implementation directly, import drivecourse; drivecourse.course_loop_bend(radius=30.0, width=8.0, arc_pts=64); from the registry, opsdrive.get("course_loop_bend"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

周回コースの端の半円(左へ 180° 回る): 進入 (0, 0, 0) → 中心 (0, R) の周りを回って退出 (0, 2R, π)。

多角形は外側の弧(半径 R + w/2)と内側の弧(R − w/2)で囲む環の半分。面積 = π R w(閉形式)、弧を

折線にした分だけ小さく、arc_pts を増やすと収束する。規格(周回コース): 幅 8 m 以上、おおむね長円形。

Raises `ValueError`: R ≤ w/2(内側の弧が潰れる)、幅・半径が正でない、arc_pts が不正。
