Transparency is a feature, not a footnote.
The Humanoid Index uses a 6-dimension capability model to assess humanoid robots. Each dimension is scored 0–10 based on published manufacturer specifications. The overall score is a weighted average of all non-null dimensions, giving a single comparable metric across the entire index.
Each robot is evaluated across six distinct capability dimensions. Where possible, scores are derived from objective, published specifications. One dimension — Autonomy — requires editorial judgment.
| Dimension | Measures | Data Source | Scale |
|---|---|---|---|
| Readiness | Production and deployment maturity | Company status (mass production, commercial, pilot, prototype, R&D) | Mass production = 10, Commercial = 8, Pilot = 6, Prototype = 4, R&D = 2 |
| Dexterity | Manipulation capability | Degrees of freedom from published specs | Linear: 0 DOF = 0, 55 DOF = 10 |
| Mobility | Movement speed and agility | Max speed from published specs | Linear: 0 m/s = 0, 4 m/s = 10 |
| Autonomy | AI capability and independent operation | Editorial estimate based on demos, deployments, and published capabilities | Editorial judgment (see note below) |
| Payload | Load-carrying capacity | Payload capacity from published specs | Linear: 0 kg = 0, 30 kg = 10 |
| Endurance | Operational duration | Battery life from published specs | Linear: 0 hrs = 0, 8 hrs = 10 |
The overall capability score is a weighted average of all non-null dimensions. Dimensions with missing data are excluded from the calculation rather than penalized. The weights reflect relative importance to real-world deployability.
| Dimension | Weight | Rationale |
|---|---|---|
| Readiness | 1.5x | Market deployability matters most |
| Autonomy | 1.3x | AI capability is the key differentiator |
| Dexterity | 1.2x | Manipulation capability drives use cases |
| Mobility | 1.0x | Baseline weighting |
| Endurance | 1.0x | Baseline weighting |
| Payload | 0.8x | Important but secondary to other factors |
Readiness is weighted highest because market deployability is the strongest signal of real-world viability. Autonomy is weighted high because AI capability is the key differentiator between platforms that will lead and those that will follow.
Autonomy is the hardest dimension to score objectively. Unlike degrees of freedom or speed, there is no single published metric that captures a robot's AI capability.

These scores represent our best assessment and will be updated as standardized benchmarks emerge. We welcome corrections — if you believe a score is inaccurate, please contact us.
No scoring system is perfect. We believe in being transparent about ours.
