fivebar_fk — DRIVE `puck` op

• Data kinds: signal × table → any

• Call: import fullseye as fs; fs.ledger.fivebar_fk(q, link: 'dict', *, branch: 'str' = 'forward') (to call the implementation directly, import puck; puck.fivebar_fk(q, link: 'dict', *, branch: 'str' = 'forward'); from the registry, opsdrive.get("fivebar_fk"))

Usage

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

順運動学: 関節角 (q₁, q₂)(各腕の近位リンクの x 軸からの角)→ 先端 E。肘 Bᵢ = Aᵢ + l₁(cos qᵢ, sin qᵢ)、

E = 円(B₁, l₂) ∩ 円(B₂, l₂) の "forward"(x が大きい側)か "back"。返り値 `{"E", "B1", "B2"}、交わらなければ None`。
