The 5 Levels of Humanoid Autonomy

If you scroll through X (Twitter) today, you’d think General Purpose Humanoids (GPH) are months away from folding our laundry and cooking 5-course meals. The reality is more nuanced and, for developers and founders, much more interesting.

I’ve been digging into the "Self-Driving Levels" equivalent for robotics. We need a mental model to separate the hype (Level 5 sci-fi) from the commercial opportunities available right now.

Based on frameworks from SemiAnalysis, insights from roboticist Rodney Brooks here is the definitive ladder of Humanoid Autonomy.


The Framework: Agency vs. Dexterity

Unlike self-driving cars, which just need to move safely, humanoids must move (Agency) and manipulate (Dexterity).

  • Agency: Perception, planning, and navigation in unstructured environments.
  • Dexterity: Grasping, force control, and fine manipulation.

Current commercial viability lies in balancing these two.


Level 0: Scripted Motion (The Industrial Past)

Status: Mature (1980s–Present)

These are the blind giants. They execute pre-programmed trajectories with sub-millimeter precision but have zero understanding of their environment. If you move the part by 1cm, the robot fails.

5 Use Cases:

  1. Automotive Welding: The backbone of Tesla/Toyota factories.
  2. Painting: Uniform spraying of car bodies.
  3. Heavy Palletizing: Moving heavy boxes in completely caged, fixed zones.
  4. PCB Assembly: Pick-and-place machines (high speed, zero intelligence).
  5. CNC Tending: Loading raw metal into machines (requires precise fixturing).

Timeline: Mature.
Famous Bots: FANUC M-2000, KUKA quantec.


Level 1: Intelligent Pick & Place (The Visual Awakening)

Status: Commercial Scale (2023–Present)

Robots gained eyes. Using computer vision and deep learning, these systems can identify objects in a cluttered bin and pick them up. They don't "understand" the object's function, but they know where it is.

5 Use Cases:

  1. Parcel Sorting: Identifying and grabbing random Amazon packages.
  2. Agricultural Sorting: Picking good apples vs. bad apples on a conveyor.
  3. Debris Recycling: Sorting plastic from glass in waste plants.
  4. Kit Assembly: Grabbing 3 different items to put in a subscription box.
  5. Quality Control: Visually inspecting parts and removing defects.

Timeline: Standard in logistics by 2026.
Famous Bots: RightHand Robotics, Covariant (software), Fanuc with iRVision.


Level 2: Autonomous Mobility (The Explorer)

Status: Early Production (2024–2026)

Robots gained Agency. They can map a new environment, navigate around obstacles, and decide how to get from A to B. This is where Boston Dynamics’ Spot shines. Note: They can move, but they can't do much with their hands yet.

5 Use Cases:

  1. Industrial Inspection: Reading analog gauges in oil refineries.
  2. Construction Patrol: Scanning progress on building sites (BIM verification).
  3. Security: Autonomous patrolling of data centers or malls.
  4. Hazard Mapping: Entering gas-leak zones to measure toxicity.
  5. Last-Mile Delivery: Sidewalk robots (Starship) navigating crowds.

Timeline: Commercially viable now for inspection; scaling fast.
Famous Bots: Boston Dynamics Spot, ANYbotics ANYmal.


Level 3: Low-Skill Mobile Manipulation (The Founder's Sweet Spot)

Status: Pilots -> Scale (2026–2029)

This is the biggest opportunity for startups right now.
These robots combine Level 2 mobility with Level 1 vision to perform loose manipulation tasks. They can pick up a box, move it across a room, and put it down.

Crucial Insight: They struggle with force control. They can't thread a needle or peel a potato perfectly because they lack tactile feeling. But they can fry a basket of fries.

5 Use Cases:

  1. Specialized Cooking (The "Fry Cook"): Dumping baskets of fries, flipping burgers (requires timing, not fine touch).
  2. Warehouse Restocking: Taking a tote from a pallet and sliding it onto a shelf.
  3. Laundry Loading: Picking up dirty clothes and shoving them into a washer.
  4. Hospital Logistics: Delivering lab samples or food trays to nurse stations.
  5. Trash Collection: Navigating an office to empty bins into a main cart.

Timeline: Pilots 2025; Scale 2027-2028.
Famous Bots: Figure 01 (BMW pilot), Tesla Optimus (Factory transport), Chef Robotics (Modular arms).

Note: You don't need legs for this! A wheeled robot with an arm is 80% cheaper and 100% more stable for a kitchen.


Level 4: Force-Dependent Dexterity (The "Rodney Brooks" Wall)

Status: Research Lab (2028+)

This is the barrier. To be a "General Purpose" humanoid, a robot needs tactile sensing (touch). It needs to feel if a screw is cross-threaded, or if a tomato is too soft to slice.

Rodney Brooks (founder of iRobot) argues this is the "hard part" the industry is underestimating. We have great vision (VLAs), but terrible touch.

5 Use Cases:

  1. Full-Service Chef: Slicing veggies, seasoning to taste, plating delicate herbs.
  2. Elder Care: Helping someone stand up (requires sensing their balance/frailty).
  3. Skilled Trades: Installing electrical outlets or plumbing fixtures.
  4. Textile Work: Buttoning a shirt or tying shoelaces.
  5. Complex Assembly: Inserting flexible rubber gaskets into car doors.

Timeline: Research prototypes 2029; Commercial 2032+.
Famous Bots: None commercially yet. Lab prototypes from MIT/Stanford.


Level 5: Fully General Autonomy

Status: Sci-Fi (2032?)

A robot that can walk into a strange house, look around, and cook a specific family recipe using tools it has never seen before, without internet access.


The "ADAS vs. FSD" Split: Why One Size Won't Fit All

We often talk about humanoids as a monolith—one robot to rule them all. But look at the automotive industry. We didn't jump straight to Level 5 Robotaxis. Instead, we have a split market: 99% of cars have ADAS (Lane Keep, Cruise Control) and <1% attempt FSD (Full Self-Driving).

Robotics will follow this exact same bifurcation.

We aren't going to see a single "iPhone of Robots." Instead, Economics, Battery Life, Safety, and Compute will force the market into two distinct categories:

Category 1: The "ADAS" Class (High Utility, Low Risk)

  • The Build: Wheeled bases, specialized grippers, constrained compute (e.g., Jetson Orin Nano).
  • Battery & Economics: Wheels are 10x more energy-efficient than legs. Without the need to run a massive VLA model for every movement, these bots can run for 8-10 hours on a charge and cost <$10k.
  • Adoption Vector: These will dominate critical safety areas first. Think radioactive waste handling, chemical spill cleanup, or repetitive high-heat industrial cooking. The ROI is immediate because the task is defined.

Category 2: The "FSD" Class (High Agency, High Cost)

  • The Build: Bipedal, humanoid hands, massive onboard inference compute.
  • Battery & Economics: Balancing on two legs consumes massive power. Running a "Common Sense" brain drains the rest. These will cost $50k+ and last 2-4 hours.
  • Adoption Vector: Research labs, luxury home help (eventually), and unstructured environments where wheels physically cannot go.

What’s Your Bet?

The robotics industry is currently split between two philosophies: the "iPhone moment" where one hardware platform does everything (Level 4/5 Humanoids), and the "App Store" reality where specialized tools solve specific problems today (Level 3 Mobile Manipulators).

I’d love to hear your take:

  • Do you think I’m underestimating how fast VLA (Vision-Language-Action) models will solve the "dexterity gap"?
  • Are you currently working on a Level 2 or Level 3 project?
  • What’s the one "boring" chore you’d pay a Level 3 robot to do right now?
