Robotics has a census authority. The International Federation of Robotics counts installations and operational stock, and does it well — 4.28 million industrial robots at last count. What robotics does not have is a value authority. Nobody publishes what robots actually cost, what they're worth used, or which announced machines are actually shipping.
There's a structural reason for that gap: the census body is an OEM trade association, and no trade association publishes honest depreciation data about its members' products. The seat isn't unoccupied by accident. Every mature asset class fills it eventually — vehicles got their blue books, aircraft got their appraisal houses, heavy equipment got its value guides. Robotics is next, and someone neutral has to do it.
So we're doing it. The Robot Ledger is a new publication dedicated to observed robot economics: prices as they actually appear, archived with checksums at the moment of capture, corrected in public and never rewritten. Today we're publishing Print #001 of the Robot Frontier Price Index — the lowest observed price of a shipping robot in each category we track.
The inaugural numbers
| Category | Frontier entry price | YoY | Coverage | |---|---|---|---| | Humanoid | $13,500 | −15.6% | 2024-07 → present | | Quadruped platform | $1,600 | flat | 2023-07 → present | | Autonomous tractor | $74,998* | — | last public price: July 2024 |
Three stories hide in that small table.
The humanoid frontier is falling fast. The cheapest shipping humanoid held a $16,000 list price for at least a year, then repriced to $13,500 in late 2025 — a 15.6% drop in the category's entry price in under two years. If you're modeling humanoid economics on launch-era prices, your numbers are already stale.
The quadruped frontier hasn't moved in three years. The entry price has sat at $1,600 since mid-2023, with the entire variant ladder unchanged since launch. Two adjacent robot categories, two completely different price regimes — which is exactly why category-level indices matter.
Agricultural autonomy went dark. The leading electric autonomous tractor listed at $88,998 in early 2024, cut to $74,998 by mid-year — and then the price disappeared from public view entirely. It hasn't returned. We report the last observed figure with its date. We don't estimate.
The finding behind the index
Here's the fact that convinced us this publication needs to exist: across five years of archived pages from the major industrial-arm, cobot, and warehouse-robot manufacturers, not one published a U.S. dollar price. Robot pricing is structurally opaque — quote-gated, distributor-mediated, invisible to anyone trying to make a capital decision. The categories where prices are public (humanoids, quadrupeds) are the exception, not the rule. Opacity like that is a tax on every buyer, every lender, and every board trying to plan an automation budget.
The index will also track two things nobody else maintains: a price-visibility tracker (which categories publish prices at all, and when prices appear or vanish — the tractor going dark is a data point, not a footnote) and an announced-vs-shipping watch (a running, dated record of which headline robot programs have observed prices on shipping units, and which remain announcements). Machines enter the index when they ship at an observable price — not when they're demoed.
The rules we publish under
Observed prices only, captured from public sources and archived with checksums at capture time — every figure above traces to a dated archive entry. Versioned methodology: when our normalization basis improves, history is restated under the new version, openly. Corrections appear in the next print; prior prints are never edited. And this publication reports observed market state only — no forecasts, no fitted curves, no speculation dressed as data.
The Robot Ledger will publish quarterly prints plus research between them, and will be moving to its own home shortly. If you make, finance, buy, or study robots and think a number in this print deserves scrutiny — good. That's the point. The receipts exist.
