wrist_stiffness_fit — DRIVE `pegtactile` op

• Data kinds: signal × signal → table

• Call: import fullseye as fs; fs.ledger.wrist_stiffness_fit(dx, F, min_span: 'float' = 2e-05) -> 'dict' (to call the implementation directly, import pegtactile; pegtactile.wrist_stiffness_fit(dx, F, min_span: 'float' = 2e-05) -> 'dict'; from the registry, opsdrive.get("wrist_stiffness_fit"))

Usage

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

手首のたわみ Δx(手首カメラ)と、ペグが受ける接触力の同じ成分 F から k = Σ FΔx / ΣΔx²(原点を通る最小二乗、準静的な釣り合い

F_contact + F_spring ≈ 0 ⇒ F_contact = kΔx)。回転(角とモーメント)にも同じ式で使える。返り `k・r2・rms_N・n・span`。

Raises ValueError: 点が 3 未満、形が違う、有限でない、Δx の幅が `min_span` 未満(悪条件: 動いていないばねの k は決まらない)。
