A backbone-free serving layer for robot policies that caches complete action chunks
from past executions, with action-level residual correction and progress-guided policy refresh —
1.4×–11× lower latency and 2.0×–2.2× higher multi-robot throughput across five VLA,
world-action, and diffusion policies and a real SO-101 arm, without modifying the policy.

Hybrid pipeline parallelism for LLM training across heterogeneous edge devices:
a DP-based Pareto-optimal model partitioner under latency and energy constraints,
plus a network-aware wavefront scheduler with online re-planning —
1.1×–6.3× end-to-end improvement over the state of the art.
