Learning to Act under Visual Interruptions with Vision-Language-Action Models

MINT is proposed, which first trains VLA policies to remain functional under missing visual inputs, and selectively supplements missing observations using optical-flow extrapolation or an action-conditioned world model, and withdraws predicted views when they become unreliable.

RoboFL: Federated Expert Assembly for World Action Models

RoboFL, which instantiates MoSAIC (Mixture of Slotted Adapters) for federated world-action learning, is presented, as it outperforms centralized PEFT InternVLA-A1 by 12.23% on the Franka arm, while reducing per-round client communication by up to 86.81% relative to MoE-based federated VLA baselines.

Don't Throw Away the Tail: Action Upcycling for Policy Acceleration

This work proposes Action Upcycling, a training-free algorithm that reuses actions the policy would otherwise discard, without accessing model internals or drawing extra samples, and finds that discarded actions stay close to their replanned versions as long as the action velocity remains smooth.

Sufficiency of Zeroth-Order Reward Shaping for Policy Gradient in Stabilization Control

This work theoretically and empirically demonstrate that policy gradient methods can successfully solve stabilization tasks without first-order reward terms, and confirms that reward functions must be zeroth-order complete over goal-relevant coordinates, while the first-order state remains necessary in the policy obser...

Efficient World Action Model Inference with Adaptive Intermediate States

World Action Models (WAMs) enable future-aware control by jointly modeling actions and environment dynamics. However, iterative diffusion or flow inference incurs substantial denoising latency. Prior inference state offers a natural opportunity for acceleration, yet changing planning contexts, observations, and interme...

LRC-JEPA: Disentangling Dynamics and Residual Context for Efficient World Models

This work introduces LRC-JEPA, a lightweight end-to-end world model that routes information into a compact predictive latent and learned-query residual-context embeddings and shows that the resulting representation is sufficient, minimal, nuisance-invariant, and disentangled.

Predictive Semantic Safety: From Visual Physical Reasoning to Safety-Critical Control

A framework termed Predictive Semantic Safety (PSS), which connects visual physical reasoning to backup-based safety filtering and derives input-affine constraints for minimally modifying the nominal input while preserving backup feasibility under the robot dynamics and input limits.

When World Models Lie: Adaptive Safety Analysis Under Wrong Imaginations

World models offer a powerful substrate for safety reasoning in high-dimensional robotic systems, but they are also fallible: their predictions can be biased, miscalibrated, or confidently wrong. This creates a central challenge for latent-space safety filters, which often learn Hamilton-Jacobi safety value functions o...

Bayesian Active Learning for Intent Disambiguation in Interactive Robot Planning

This work proposes a Bayesian framework that treats clarification as an active learning problem over grounded Signal Temporal Logic task specifications and uses LLMs to initialize candidate formal specifications and translate informative contrasts into natural-language clarification questions, while Bayesian optimizati...

SAGE: Symbolic Action-Gating and Editing for LLM Task Planners

SAGE (Symbolic Action-Gating and Editing), a single-LLM planner built from two lightweight mechanisms: a domain-agnostic symbolic gate that blocks precondition-violating actions with typed reasons as a runtime safety monitor, and a local edit that regenerates only the failed sub-goal's suffix, keeping completed and unt...

Offloaded inference for real-world physical AI robotics

Robots are getting smarter, but how can their hardware match that growth? New Microsoft Research findings show that moving AI inference beyond the robot can improve task success, boost efficiency, and support more advanced physical AI workloads. The post Offloaded inference for real-world physical AI robotics appeared first on Microsoft Research.
