Robotics as a Service
The robot is the cost. The work is the revenue. The question is who keeps it.
Investments · September 2026 · This page and two parts
Seven cars registered with the Texas Department of Motor Vehicles in the last week of August have no steering wheel, no pedals, and no buyer. Tesla built them to keep. From today, September 3, 2026, they carry paying passengers around Austin, and every fare goes to the company that built the car.
A Product That Never Leaves the Builder's Books
That is the whole business model, and the robotics industry has a name for it: robotics as a service, RaaS for short. The customer never buys the robot. They pay for what it does. A ride, an hour of labor, a delivered package, a picked order, a surgery. The maker, or whoever owns the machine, carries its cost and keeps the stream.
This series is about that model, because it changes what a product is. A car sold to a customer is a transaction: revenue once, margin once, and the electricity, insurance, and wear are somebody else's problem after the paperwork. A car kept and driven for fares is an asset. It cost money to build, it sits on a balance sheet, it loses value every year, and in exchange it earns money every day it works. In accounting language the first is a sale and the second is capital spending that produces operating revenue. In plain language, the price tag stops being the end of the story and becomes the beginning of it.
The investment question follows from the accounting. An asset that earns by working can be valued by what it earns, the way a rental property or a jet engine is. The two pieces in this series run that arithmetic on the Cybercab and on Optimus, Tesla's humanoid robot. This page sets the frame: where the model came from, who else is running it, the five numbers every RaaS business lives or dies on, and who gets paid in what order.
One housekeeping note. In computer security, RaaS also means ransomware as a service, in which criminals rent out extortion software. Different industry, same acronym. Nothing here concerns it.
The Idea Is Older Than the Robots
In 1959 Xerox shipped the 914, the first plain-paper copier. It listed at $29,500, which almost no office would pay. So Xerox did not ask them to. It leased the machine for $95 a month, threw in the first 2,000 copies, and charged four cents for every copy after that. Offices copied far more than 2,000 pages a month, and the commercial copying business grew from roughly $40 million a year to $400 million by 1962. The machine stayed on Xerox's books. The copies paid for it many times over.
Three years later, in 1962, Bristol Siddeley offered buyers of the new de Havilland 125 business jet a deal on its Viper engines: a fixed price per flying hour, covering the engine and its replacement, instead of a bill for every repair. Rolls-Royce later trademarked the name, Power by the Hour, and still sells jet engines that way. The operator pays only for hours the engine runs. The maker gets paid only when the engine works. Both sides now want the same thing, which is a reliable engine.
Those two deals are the ancestors of every RaaS contract. The pattern holds whenever the machine is expensive, the output is easy to count, and the maker knows more about keeping the machine running than the customer does. A robot is all three at once.
Who Is Already Running It
| Company | Robot | How it is paid | One number |
|---|---|---|---|
| Waymo (Alphabet) | Jaguar I-Pace, Zeekr Ojai | Per ride, in the app | 500,000+ paid rides a week on about 3,700 vehicles. Raised $16 billion in February 2026 at a $126 billion valuation. |
| Intuitive Surgical | da Vinci | System sold or leased, then instruments and service per procedure | About 84% of 2025 revenue, on $10.1 billion, was recurring. |
| Agility Robotics | Digit, a humanoid | Per hour, under a multi-year contract with the logistics firm GXO | Rate undisclosed. The comparison it is priced against is a warehouse worker at about $30 an hour. |
| Formic | Industrial arms | Per hour; the machine stays on Formic's books | Named the model. |
| Amazon | Kiva and its descendants | Not sold at all. Amazon bought Kiva for $775 million in 2012 and kept every robot for itself | More than a million in service. |
| 1X | NEO, a home humanoid | $20,000 to buy, or $499 a month on a six-month minimum | Deliveries began in 2026. Tasks it has not learned are done by a remote operator. |
| Unitree | G1 humanoid | Sold outright | $13,500 direct from China. The price floor for the field. |
| iRobot | Roomba | Sold once, no stream | Filed for bankruptcy protection on December 14, 2025, and was taken over by its contract manufacturer. |
Read down the third column. The companies with a stream are raising money or compounding it. The one that sold a robot once and hoped you would buy another ended up owned by its supplier. That is one data point, and iRobot had troubles besides its model. But it is the reason the industry settled on the acronym. The service is the half that pays.
The Five Numbers
Every RaaS business, from the copier to the humanoid, reduces to five inputs.
| Input | What it means |
|---|---|
| Cost of the robot | What it takes to build or buy one. The capital cost. It lands first, before any revenue. |
| Price of the output | What the customer pays per ride, per hour, per copy. |
| Utilization | How much of the day the robot spends doing paid work. An idle robot is a depreciating box. |
| Operating cost per unit of output | Power, maintenance, insurance, and the humans still in the loop. |
| Useful life | How long the machine works before it is worth nothing. |
Together they produce the two figures that matter. Contribution is the price of the output minus the cost of producing it, times the volume. Payback period is the cost of the robot divided by the annual contribution: the number of months until the machine has earned itself back. After payback, the stream is profit until the useful life runs out. Before it, the company is spending.
One accounting term does most of the work in the two pieces that follow. Depreciation is the way the capital cost is spread across the useful life, so a $25,000 machine expected to last five years costs $5,000 a year on paper whether or not it earned anything that year.
Who Profits, and in What Order
Four parties sit at the table. The customer pays a fare or an hourly rate and gets the work. The operator, whoever owns the robot, keeps the fare minus the operating cost. The builder took one of three seats: it sold the robot once and is out of the picture; or it is the operator, and keeps the stream; or it takes a cut of somebody else's stream. Musk said in 2019 that Tesla owners who put their cars into the robotaxi network would keep roughly 70% to 75% of the fare and Tesla would take 25% to 30%. As of September 2026 no owner can enroll a car and no terms have been published. The shareholder owns a slice of the builder, and so a slice of whichever seat the builder took.
Tesla intends to occupy all three of the builder's seats. It builds the Cybercab, it operates the fleet, and it has said it will let private owners add cars and take a cut. Alphabet is Waymo's operator and, having put up most of the $16 billion, largely its shareholder too. Intuitive sells the robot and keeps the stream from the instruments. The model is the same across all of them. The seat is what differs, and the seat decides whether revenue arrives once or every year.
The Cost Lands First
One more thing, and the series would be dishonest without it. RaaS spends before it earns. Tesla's capital spending in the second quarter of 2026 was $5.79 billion, more than double a year earlier, and free cash flow was negative $1.09 billion. Management said it expects that to continue for several quarters. Waymo has taken more than $21 billion from Alphabet and outside investors since late 2024 and does not publish a profit. Every robot in the table above was paid for before it earned a cent, and most of them are still being paid for.
That gap, between the cost today and the stream later, is what anyone who invests in a RaaS company is buying. The stream can arrive smaller than promised, later than promised, or not at all. The arithmetic in the next two pieces shows what has to be true for it to arrive at the size Tesla wrote into its own milestones. It does not say whether it will. Franklin Hugh Money teaches how things work and never what to buy, and this series is no exception.
The arithmetic of a $25,000 robot on a $1.40-a-mile fare card: utilization borrowed from Waymo, operating cost from Tesla and from Morgan Stanley, and the five things that have to be true for a million of them.
Depreciation by the hour, the one variable nobody outside Tesla can measure, and the choice between selling a robot once and renting it for five years.
