Ablation_Cup_physical_raw

Cup-handover visual vs physical DR ablation (data_collection/cup_basket/ablation_vp, 2026-11-07), PHYSICAL set: raw collector output of every part (24 envs per part, failures included; the LeRobot set Ablation_Cup_physical keeps the first 2,000 successes in part order). Physical randomization only: start pose +-2 deg on both arms, table height -2/-1/0/+1/+2 cm cycled per part, camera mount and FOV jitter. Table, backdrop, lights and cup colour nominal.

Raw Isaac Lab / Isaac Sim 5.1 collector output for the ROBOTIS FFW SG2 (cyclo_lab real2sim pipeline, padiredd). Kept because it has what the converted LeRobot sets do not: full-resolution video, per-episode randomisation / object metadata and the failed attempts (success: false).
