force_from_wrist_displacement — DRIVE cutting op

• Data kinds: signal × signal × scalar → signal

• Call: import fullseye as fs; fs.ledger.force_from_wrist_displacement(z_meas_mm, z_cmd_mm, k_n_per_mm: 'float') (to call the implementation directly, import cutting; cutting.force_from_wrist_displacement(z_meas_mm, z_cmd_mm, k_n_per_mm: 'float'); from the registry, opsdrive.get("force_from_wrist_displacement"))

Usage

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

柔らかい手首(縦のばね k、N/mm)なら押し力 F = k (z_meas − z_cmd): 刃が指令より上に残った分が力(N の配列)。

準静的の近似: 手首の慣性と減衰は入らない。減衰 c の手首を速さ v で下げると、空中での風袋引きに c·v が入り、刃が食材に

止められている間だけそれが抜ける —— 誤差の上限は c·v(PoC の --full で MuJoCo の拘束力と比べる)。
