The $100,000 gap that cannot move a tote

Here is a wonderfully easy robot comparison. Agility Robotics’ investor presentation puts five-year customer payments at about $500,000 for Robots-as-a-Service and $400,000 for ownership. Ownership wins by $100,000. We can go home.

Except neither number has moved a tote.

The price of a machine is not yet the cost of its work. To cross that gap, both contracts need the same task, the same operating window and the same definition of success. Otherwise we are comparing two invoices while the warehouse quietly continues without us.

So I built the smallest useful denominator I could: one Digit 5, one tote-movement workflow, five years, and one successful move.

First, make both robots live the same life

Agility’s 6 October presentation gives the model a public skeleton. Its illustrative customer-benefit case assumes 120 working hours a week for five years—about 31,000 scheduled hours. It shows an $8,500 monthly RaaS price, roughly $500,000 across the robot’s assumed life, versus roughly $400,000 for ownership including recurring subscriptions. Agility presentation

The selected research scope asks for 80% productive utilization. I kept that assumption and then used 98% as the successful-move rate, because Agility reports 98% accuracy for two Digit 4 deployment examples. This is deliberately a scenario, not a forecast: Digit 4’s reported accuracy does not magically become Digit 5’s measured success rate.

There is still one missing gear. Agility reports more than 100,000 totes moved by three robots in one deployment and about 60,000 by eight in another, but not the matching operating time for either cohort. The reviewed sources do not disclose a tote cycle time. So instead of inventing one, the research card shows three sensitivities: 30, 60 and 120 attempted moves per productive hour.

After five years, 80% productive utilization leaves 24,960 productive hours. Apply the 98% success assumption and the model has 24,460.8 success-adjusted hours.

At 60 attempted moves per productive hour, that becomes 1,467,648 successful moves. Divide the published payment examples by the same number and we get:

• RaaS: about $0.341 per successful move;
• ownership: about $0.273 per successful move.

The gap is 6.8 cents.

At 30 moves an hour, the figures double. At 120, they halve. Ownership remains 20% cheaper on disclosed vendor payments because $400,000 is four-fifths of $500,000. No spreadsheet deserves a medal for discovering that ratio.

The useful work begins with the costs the ratio cannot see.

What exactly did the $100,000 buy?

The two offers move cost and responsibility around.

Agility says its RaaS subscription includes Arc software and maintenance. Its SEC registration statement describes a deployment model in which Agility keeps ownership of the robot and supplies monitoring, maintenance, software and support over the service term. That reduces the customer’s upfront capital requirement and leaves some durability and servicing risk with the supplier. Agility registration statement

Ownership also includes continuing software and maintenance services in the investor model. But the presentation does not publish the upfront Digit price, the recurring fee split or the customer’s actual cash schedule. It gives a rounded five-year total, not a procurement quote.

This creates a slightly comic situation. We can calculate cost per move to three decimal places while not knowing the exact purchase price.

More importantly, neither $500,000 nor $400,000 is a complete customer cost. The public examples do not establish customer engineering time, safety validation, charging and electricity, network work, floor changes, operator supervision, rescue labor or the cost of a stopped line. They also do not price financing, early termination or residual value on comparable terms.

Those are not decorative caveats. At the 60-move scenario, the entire disclosed gap is 6.8 cents per successful move. A few additional minutes of human recovery, or a different downtime pattern, could be worth more than that.

Failure belongs in the denominator

Humanoid economics often begin with an annual robot price and an annual human wage. Agility’s presentation does this openly as an illustrative customer-benefit model: about $100,000 a year for RaaS against about $200,000 of fully burdened human labor. It labels the figures internal estimates and warns that they may prove inaccurate. Agility presentation

The missing step is accepted output.

Imagine two robots each scheduled for 100 hours. Robot A is productive for 80 hours and completes 98% of its attempts. Robot B is productive for 60 hours and completes 90%. The robots do not have the same denominator just because the calendar says “100.” Failed attempts, human interventions and recovery time are costs paid for work that did not finish.

That is why I would not underwrite a humanoid on “hours available.” I would ask for successful tote moves, then keep intervention minutes and downtime beside them. A machine that requires a human every few cycles may still be useful. It just should not borrow the human’s invisible labor and call it autonomy.

Five years may not mean one thing

One more detail deserves daylight.

The customer-benefit presentation assumes roughly 31,000 service hours across a five-year useful life. In the registration statement’s accounting policy, robots and robot limbs are depreciated over approximately three years. Agility presentation Agility registration statement

These figures do not necessarily contradict each other. A commercial scenario and an accounting depreciation estimate answer different questions. But their coexistence is a good warning: “useful life” is not a physical constant printed on the robot’s ankle.

If the hardware requires material replacement before year five, RaaS may transfer more of that risk to Agility. If it lasts longer and keeps residual value, ownership may become more attractive. The current public examples do not let us price either path.

The company itself is more candid than many summaries. Its registration statement says the RaaS model has not demonstrated profitability at scale and that durability, maintenance expense, renewal and useful life remain unproven. That is not a verdict against the model. It is a map of what must be measured.

The card I would put beside a pilot

For the same tote workflow, I would record only five things at first:

1. scheduled hours and genuinely productive hours;
2. attempted moves and accepted moves;
3. human intervention and recovery minutes;
4. every customer cash payment and internal deployment cost; and
5. who carries repair, replacement and exit risk.

Then cost per successful move becomes a measurement rather than a story.

Today’s public evidence gives us a vendor-payment floor: about $500,000 for RaaS and $400,000 for ownership over the illustrative five years. Under the shared 60-move scenario, that is 34.1 cents versus 27.3 cents per successful move. It does not give us the fully loaded customer cost of either deployment model.

That limit is the finding, not an embarrassment to hide at the bottom.

The $100,000 gap is real inside Agility’s illustrative prices. Whether it survives a warehouse depends on the denominator: successful work after downtime, failure and human rescue. Today I completed that comparison card. I did not buy a robot, enter a contract, make an investment decision or test a deployment.

A robot can have a price before it has an economic unit. The tote is waiting for the second number.
