pour_scene_mjcf — DRIVE scoop op

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

• Call: import fullseye as fs; fs.ledger.pour_scene_mjcf(L: 'float' = 0.06, B: 'float' = 0.04, h0: 'float' = 0.016, radius: 'float' = 0.002, *, wall: 'float' = 0.04, lip_height: 'float' = 0.15, mu_slide: 'float' = 0.16, mu_roll: 'float' = 0.09, density: 'float' = 2500.0, floor_mu: 'float' = 1.0, wall_mu: 'float' = 0.3, timestep: 'float' = 0.0015, contact_tc: 'float' = 0.006, solver_iterations: 'int' = 50, solver: 'str' = 'CG', cone: 'str' = 'elliptic', condim: 'int' = 6, seed: 'int' = 0) -> 'dict' (to call the implementation directly, import scoop; scoop.pour_scene_mjcf(L: 'float' = 0.06, B: 'float' = 0.04, h0: 'float' = 0.016, radius: 'float' = 0.002, *, wall: 'float' = 0.04, lip_height: 'float' = 0.15, mu_slide: 'float' = 0.16, mu_roll: 'float' = 0.09, density: 'float' = 2500.0, floor_mu: 'float' = 1.0, wall_mu: 'float' = 0.3, timestep: 'float' = 0.0015, contact_tc: 'float' = 0.006, solver_iterations: 'int' = 50, solver: 'str' = 'CG', cone: 'str' = 'elliptic', condim: 'int' = 6, seed: 'int' = 0) -> 'dict'; from the registry, opsdrive.get("pour_scene_mjcf"))

Usage

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

口の開いた樋(床の長さ `L、幅 B、奥壁と側壁の高さ wall)に深さ h0` まで剛体球を格子で詰めた場面の MJCF

(mujoco 不要)。樋は mocap の body(`name="trough"、原点 = 口の床の縁、高さ lip_height`)で、口を下げる向き

(y 軸まわりに −θ)に回すのは :func:scoop_mujoco_pour が毎歩 `mocap_quat` を書いて行う。床は粗く(滑り摩擦

`floor_mu、底の層が床ごと滑り出さない —— granular の粗い台と同じ役)、側壁は wall_mu`。床の口の側(x < 0)が

開いていて、こぼれた球は落ちて地面(高さ 0)に届く。

返り: `xml, positions, info`(L, B, h0, wall, radius, lip_height, mass_each, n, timestep, A_fill = L·h0)。

Raises `ValueError: h0 ≥ wall / contact_tc < 2 timestep` / 球が 1 層も入らない / 綴り違い。
