Reason within physical deadlines
Decide when to think, observe again, act, or reuse a skill within the response budget.
A Perspective on the Future of Physical AI
A New Era of Robotic Systems
A new paradigm for robots that interpret intent, reason about goals, orchestrate skills and tools, verify outcomes, and adapt.
Learned policies have expanded robot capabilities, from agile locomotion to language-guided manipulation. Vision-language-action (VLA) models map images and instructions to actions, learning from increasingly diverse robot data. Reliable generalization when scenes or instructions change remains a central challenge.
Agentic robotics centers on an agent that interprets intent, reasons about goals and constraints, coordinates skills and tools, and verifies outcomes to adapt its decisions. The ambition is to delegate broader work: from picking up a cup to preparing breakfast, and eventually taking responsibility for it day after day.
The shift changes how capabilities are organized. Learned policies remain valuable skills; the agent decides which capabilities to use, checks whether their effects satisfy the goal, and adapts when they do not. A reference framework makes these responsibilities and their interactions explicit.
Our reference framework separates three responsibilities: S2 interprets intent, decides how to proceed, and verifies outcomes; S1 supplies skills and callable modules; S0 provides the body interface and local real-time control. One model may serve several roles, and one role may span several components.
A decision can reach the body through existing skills, permitted S0 targets, or a program written by S2.
Execution returns evidence to S2. Bringing a cup to the table requires checking that it was grasped, remains held during transport, and reaches the intended place before reporting completion.
S2 makes two externally identifiable decisions: how to proceed, and whether the intended outcome was achieved. The foundation model supplies knowledge, understanding, and reasoning; the embodied harness provides context, tools, plans, memory, and verification. Together they connect those decisions to physical execution.
The world keeps changing while S2 reasons. Decisions must arrive in time, use fresh observations, and respond to changes in the user’s request or the scene. Capped scaling captures this objective: improve decision quality within the physical deadline.
These constraints make evaluation a question of both capability and execution. Model-level tests isolate abilities under specified inputs; system-level tests measure what the model, harness, skills, and body achieve together. The framework covers eight abilities and the resources consumed as cost.
Fix the harness when comparing models; fix the model when comparing harnesses.
Report deadlines, observation age, and paused versus live execution separately.
Use evidence-based outcome checks and disclose false completion claims.
The studies reviewed in the paper report gains in semantic and spatial capabilities, while physical execution, completion judging, and timely response remain uneven. These comparisons show how interfaces, the world clock, and the move from text to action affect reported performance.
Reported comparisons from individual studies. Each row uses its own task, metric, and protocol.
| Study / Metric | Reported Comparison | Setting | What It Shows |
|---|---|---|---|
| EmbodiedSkillBenchSuccess Rate | 92% / 61% / 85%Native / Skill-Only / Selective Reuse (ADR) | GPT-6 Astra; 100 perturbed LIBERO-Pro tasks. | The tool interface can constrain performance. |
| RT-SafeSafe Success | 19.8% → 0.7%Paused World → Live World | Eight VLMs; hard routes; mode-specific timing instructions. | Live execution changes the safety result. |
| RoboHarmRefusal Rate | 72% → 18%Text → Robot Actions | Six models; real-robot end-effector control. | Refusal in text transfers only partly to action. |
These rows use different tasks and metrics and do not form a cross-benchmark ranking. Refusal rate is distinct from safe task completion.
These gaps help explain why progress in digital agents does not transfer directly to robots. Coding agents benefit from familiar interfaces, verifiable outcomes, abundant data, and inexpensive environments. Physical robots weaken all four conditions at once.
The organizing principles still transfer: act on feedback, define tool contracts, maintain durable state, separate execution from judgment, and reuse validated skills. Their physical implementation requires grounded interfaces, calibrated verifiers, embodied data, and simulation checked against reality.
Rebuilding these foundations should expand the work people can entrust to a robot. Our ladder measures progress by the responsibility a robot can organize, verify, and sustain: from a primitive to a task, a workflow, and a standing role.
Current systems complete primitives and tasks. Workflow-level evidence is emerging in company demonstrations; a sustained role in an unstructured environment without human repair remains unestablished.
Responsibility and spatial scope are separate axes. Existing benchmarks cover parts of this space, mostly within primitives and single tasks. Their spatial reach and time span show where evaluation has extended and where evidence for workflows and standing roles is still missing.
Selected examples from the paper’s benchmark-coverage table.
| Benchmark | Spatial Scope | Time Span |
|---|---|---|
| LIBERO | Workcell | Single Episodes |
| RoboMME-Interference | Workcell | Prior Demonstration Followed by Unrelated Sessions |
| RobotWorld | Workcell to Outdoor | Interaction Budgets |
| MessyMem | Room / Kitchen | Over Three Hours; 25 Consecutive Tasks Without Resetting Memory or the Environment |
| R2R-CE | Building | Single Episodes |
| BEHAVIOR-1K | Building / Homes and Offices | Single Long Episodes |
| RT-Safe | Site / City Routes | Continuous Time |
The paper finds a gap in tests of interdependent workflows and roles sustained over days. A long sequence of tasks is not sufficient evidence of either.
Decide when to think, observe again, act, or reuse a skill within the response budget.
Maintain trustworthy state across tasks and spaces, and coordinate work with shared resources.
Reuse verified experience, expose capabilities explicitly, and reduce data and configuration needs.
Retain changes that help later work without eroding existing abilities.
Progress in these directions should carry forward to later work. Test improvements on held-out tasks, check that existing abilities are retained, and identify what changed in the model, harness, or skills.
The value of this research becomes concrete where people still choose the next task, judge completion, and handle exceptions. Embodied S2 could take on more of these responsibilities, helping robots follow varied requests, recover from routine failures, and carry useful state across tasks and days.
Interpret open requests, remember preferences, and recover when a chore fails.
Verify cycles, handle exceptions, and re-task skills when production changes.
Follow anomalous readings with further checks and evidence-backed reports.
Handle varied requests, verify outcomes, and preserve provenance.
Switch jobs from observations and widen operating domains as safety evidence grows.
Across these settings, progress means more useful work delivered with less human intervention. Reliability, time, cost, and the assistance still required show how much responsibility people can entrust to a robot.
