puck_state_at — DRIVE puck op

• Data kinds: table × signal → table

• Call: import fullseye as fs; fs.ledger.puck_state_at(pred: 'dict', t) -> 'dict' (to call the implementation directly, import puck; puck.puck_state_at(pred: 'dict', t) -> 'dict'; from the registry, opsdrive.get("puck_state_at"))

Usage

Position and velocity on the path of puck_slide_predict at time t (scalar or (N,)). After the end, the end state is kept (the position does not move; the velocity is the end value = 0 if stopped). Return value {"p" (N,2), "v" (N,2)}.
