g1-inspire-redball-n16-waist
GR00T N1.6 fine-tune for the Unitree G1 + Inspire RH56DFTP red-ball
pick-and-place task, with waist control — the successor to
birbirll/g1-inspire-redball-n16
trained on the 33-D action layout (7+7 arms, 6+6 hands, 3 waist, nav(3) +
base_height, waist actions derived from state with a +6-frame lead).
Status
- Sim-validated (2026-07-27): open-loop waist correlation 1.00 vs the
dataset; closed-loop lean delivery ~102% under the deploy WBC with
--waist-authority manip+ droop compensation (VLAPolicyBridge vendored WBC). Zero balance incidents in sim runs. - Pending on-robot retest — treat as a sim-proven candidate, not a hardware-certified policy. Supervise with the kill switch armed.
Serving
Serve the repo ROOT with the VLAPolicyBridge console (redball_waist
lanes resolve it tier-1). On a deploy machine:

Training: continuation (weights-only) from the 33-D waist retrain's checkpoint-7000; recipe = piston-v2 (paged_adamw_8bit, grad ckpt, bs 8, state-dropout 0.8, color jitter) on a single RTX 4090.
