stall_verdict — DRIVE pegtactile op

• Data kinds: table × scalar × any → table

• Call: import fullseye as fs; fs.ledger.stall_verdict(kp, theta: 'float', mu_hat) -> 'dict' (to call the implementation directly, import pegtactile; pegtactile.stall_verdict(kp, theta: 'float', mu_hat) -> 'dict'; from the registry, opsdrive.get("stall_verdict"))

Usage

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

二点接触で止まった時の Whitney の判定(OCW p.28): θ > c/μ̂ ならくさび(力を抜いても抜けない側)、以下ならかじり(力の向きで

解ける)。c = (R − r)/R。μ̂ は同じ挿入の滑りの区間で触覚から読んだ値(:func:friction_from_single_contact)、None か ≤ 0 なら

推測せず `"unknown"。返り verdict("wedging" / "jamming" / "unknown")・theta_limit`。Raises ValueError: θ が有限でないか負。
