In-context imitation: add in-depth pages for ICRT, Behavior Prompting, MimicDroid (w/ paper figures + arXiv) - Review-ICRT (arXiv 2408.15980, ICRA'25, Berkeley): causal-transformer next- token ICL over sensorimotor tokens — the cluster-E anchor; method figure. Framed as the reference the newer papers improve on (SSM/visual-reasoning/data). - Review-Behavior-Prompting (arXiv 2606.30457, Stanford/Shuran Song): single-demo 'behavior prompt' via cross-attn prompt encoder + diffusion decoder; key finding = task diversity drives prompting; iPhUMI handheld data + DrawAnything/LIBERO-Gen. Architecture figure. - Review-MimicDroid (arXiv 2509.09769, ICRA'26, UT Austin RPL): learns ICL from unlabeled human play video (no teleop) via similar-behavior pairs + wrist-pose retargeting + patch masking; ~2x real success. Overview figure. - Linked all three from Review-In-Context-Imitation (clusters E/F + comparison table). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
