π0.5 AXIS joint-space policy — v1 step 2000
OpenRoboto (Bittensor SN80) AXIS v1.0 · π0.5 submission.
Parent and training method
- Parent (canonical round base):
Fisher-Wang/pi05-axis-v0.2-all30-40p50@6c1a780d59551ea0a09204a592ead726a809e80b - Method: full fine-tune (no LoRA) with openpi @
15a9616a, configpi05_axis_joint(π0.5, discrete state input, action horizon 10), 2000 steps, global batch 256, AdamW, cosine LR 5e-5 → 5e-6, EMA 0.999, training-time joint-state noise (σ 0.005 rad). - Data: perturbed, checker-filtered MuJoCo 3.11 rollouts of AXIS tasks 31, 33, 34, 35, 40, 41, 46, 48, 51, 52, 53, 54, 56 (2,528 episodes, 142k frames at 5 Hz), rendered from camera0 256×256.
- Interface unchanged: camera0 RGB + 9D joint state in, 9D absolute joint targets out;
assets/axis-v0.1-task501-runtime-v1/norm_stats.jsonis byte-identical to the parent's.
