Quadruped / Legged
7 robots · scored byQMX
Four-legged robots for inspection, security and rough-terrain work, with or without a mounted arm.
Quadruped Robots in 2026: the market at a glance
This category contains 7 ranked quadruped robots from 4 companies in 3 countries. The QMX is a specification score; legacy admission does not establish field-level review or independent task testing.
7 of the 7 records are at commercial or limited-production stage. These recorded maturity claims do not establish paid deployments or operating performance.
How this category is scored
The Quadruped Metric (QMX), version
0.2.0. Pillars are weighted for what
actually matters to this class, and normalised against
quadruped / legged-specific reference scales.
Not applicable to this category: Ecosystem & Viability. These pillars are excluded from the index and the remaining weights renormalised — not scored zero.
Category profile
Every company in this category is re-checked on the cadence above by the research agents, and every proposed change is reviewed before it reaches this page.

Why the QMX weighs what it weighs
The published reasoning behind every pillar weight in
the Quadruped Metric, version 0.2.0.
- Mobility (0.28) — the reason the class exists. Wheels stop at stairs and rubble; legs are bought to keep going. Speed, endurance and climbable slope, with endurance weighted equal to speed because an inspection round is measured in hours, not metres per second.
- Autonomy (0.25) — unchanged from every other class. A patrol robot a human has to drive is a very expensive camera on a stick.
- Hardware (0.22) — articulation, carried payload, payload-to-weight, and ingress protection, which matters here and nowhere else on the platform: these machines are sold for substations, refineries and offshore decks.
- Commercial (0.17) — quadrupeds are a genuinely shipping product with named industrial deployments, so realised deployment weighs more than it does for a class still mostly in prototype.
- Manipulation (0.08) — scored, but light, and on arm payload and reach rather than hand dexterity. A bare chassis and an arm-equipped one are different products; no machine in the class has a dexterous hand.
- Ecosystem (0.00) — excluded. The class is dominated by units inside large firms (Boston Dynamics/Hyundai, ANYbotics, Unitree) where a startup funding round is not a meaningful signal, and scoring it would mostly measure which parent happens to disclose.
