puck_slide_predict — DRIVE `puck` op

• Data kinds: signal × signal × table × scalar → table

• Call: import fullseye as fs; fs.ledger.puck_slide_predict(p0, v0, table: 'dict', t_end: 'float', *, model: 'str' = 'coulomb', max_bounces: 'int' = 50, goals: 'bool' = True, t0: 'float' = 0.0) -> 'dict' (to call the implementation directly, import puck; puck.puck_slide_predict(p0, v0, table: 'dict', t_end: 'float', *, model: 'str' = 'coulomb', max_bounces: 'int' = 50, goals: 'bool' = True, t0: 'float' = 0.0) -> 'dict'; from the registry, opsdrive.get("puck_slide_predict"))

Usage

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

パックの経路を閉形式で繋ぐ: 区間(壁から壁)ごとに向き一定・等減速、壁で :func:puck_wall_bounce。

時計: p₀・v₀ は時刻 `t0(既定 0)の状態、t_end` はそこからの長さ。区間の時刻と交点の時刻は t0 を含む絶対時刻

(速度推定の `t_ref` を t0 に渡せば交点の時刻がカメラの時計で出る)。

`model` = "coulomb"(a = μg、停止あり)/ "viscous"(a = (c/m) v、Challenge の MJCF の減衰)/ "none"(摩擦なし)。

壁に当たる時刻は d(τ) = 必要距離の閉形式解(二次方程式か対数)。`goals=True` なら端の壁の |y| < goal_half は

ゴール(そこで終わる、event "goal")。速さが 0 になれば "stop"、時間切れは "end"。

返り値 `{"segments": [{"t0","t1","p0","v0","u","s0","event"}, …], "t_end", "p_end", "v_end", "n_bounces", "events"}`。

経路の位置は :func:puck_state_at。鏡映法(:func:puck_mirror_path、摩擦なし・e = kₜ = 1)と 1e-9 で一致(門)。
