diabolo_scene_mjcf — DRIVE diabolo op

• Data kinds: table → any

• Call: import fullseye as fs; fs.ledger.diabolo_scene_mjcf(params: 'dict', *, timestep: 'float' = 0.00025, solref=(0.0005, 1.0), wrap_axle: 'bool' = False) -> 'str' (to call the implementation directly, import diabolo; diabolo.diabolo_scene_mjcf(params: 'dict', *, timestep: 'float' = 0.00025, solref=(0.0005, 1.0), wrap_axle: 'bool' = False) -> 'str'; from the registry, opsdrive.get("diabolo_scene_mjcf"))

Usage

第 2 実装の場面の MJCF 文字列(mujoco 不要): 空間テンドン 棒の先 → ディアボロ → 棒の先、長さの上限 = 糸(片側拘束 =

伸びた時だけ引く = 摩擦のない滑車の厳密模型と同じ物理を、柔らかい拘束と暗黙の速度更新という別の解法で解く)。棒の先は

mocap(各ステップで位置を書き込む)。ディアボロは自由関節の剛体(質量 = 論文の表 I、慣性は仮定。回転は糸と結合しない)。

`wrap_axle` = True なら軸(半径 r)の円柱にテンドンを巻き付ける形(下側を通す、未検証)。

Raises `ValueError`: params の形、timestep ≤ 0、solref が 2 つの正の数でない。
