peg_params — DRIVE pegsim 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.peg_params(r: 'float' = 0.005, R: 'float' = 0.0052, hole_depth: 'float' = 0.02, chamfer: 'float' = 0.001, chamfer_deg: 'float' = 45.0, peg_length: 'float' = 0.04, mu: 'float' = 0.3, n_seg: 'int' = 36, k_trans: 'float' = 600.0, k_rot: 'float' = 1.5, image_size=(640, 480), fovy_deg: 'float' = 40.0) -> 'dict' (to call the implementation directly, import pegsim; pegsim.peg_params(r: 'float' = 0.005, R: 'float' = 0.0052, hole_depth: 'float' = 0.02, chamfer: 'float' = 0.001, chamfer_deg: 'float' = 45.0, peg_length: 'float' = 0.04, mu: 'float' = 0.3, n_seg: 'int' = 36, k_trans: 'float' = 600.0, k_rot: 'float' = 1.5, image_size=(640, 480), fovy_deg: 'float' = 40.0) -> 'dict'; from the registry, opsdrive.get("peg_params"))

Usage

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

ペグと穴の寸法の表(m・rad): ペグ半径 r、穴半径 R、穴の深さ、面取りの幅と角、ペグ長、摩擦係数、手首剛性、手首カメラ。

既定は試作の寸法: r = 5.0 mm、R = 5.2 mm(半径 clearance 0.2 mm、c = 0.0385)、深さ 20 mm、45° の面取り 1 mm、ペグ 40 mm、

μ = 0.3(MuJoCo の滑り摩擦)。`n_seg は穴の壁を近似する箱の数(MJCF)、k_trans [N/m]・k_rot` [N m/rad] は

手首(コンプライアント支持)の並進・回転剛性、`image_size と fovy_deg` は手首カメラ。

Raises `ValueError`: r ≤ 0、R ≤ r、面取りが穴より深い、μ < 0、面取り角が (0°, 90°) の外。
