racket_params — DRIVE racket 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.racket_params(width: 'float' = 0.15, height: 'float' = 0.16, e: 'float' = 0.8, mu: 'float' = 0.6, v_max: 'float' = 6.0, a_max: 'float' = 60.0) -> 'dict' (to call the implementation directly, import racket; racket.racket_params(width: 'float' = 0.15, height: 'float' = 0.16, e: 'float' = 0.8, mu: 'float' = 0.6, v_max: 'float' = 6.0, a_max: 'float' = 60.0) -> 'dict'; from the registry, opsdrive.get("racket_params"))

Usage

Racket table: width and height of the blade [m], coefficient of restitution e and friction coefficient μ of the rubber, motion limits (speed v_max [m/s], acceleration a_max [m/s²]).

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
