U.S. Bureau of Labor Statistics

BLS OEWS May 2025 national median hourly wage, SOC 35-9011.

U.S. Bureau of Labor Statistics

Wages and salaries were 70.0% of total employer compensation cost for private industry workers in June 2026 (ECEC), so total cost = wage / 0.70.

ilostat.ilo.org

Nominal 4.4% a year, 2015-2025 (ILOSTAT hourly earnings).

Premissa

One runner-hour.

Robô
Premissa

Share of a runner-hour of work one robot-hour replaces (it carries; servers still serve).

RobotLAB (reseller)

Pudu BellaBot purchase.

RobotLAB (reseller)

BellaBot RaaS lease per month.

Premissa

Premissa

Yearly maintenance share of price.

Premissa

Premissa

Availability.

Premissa

Work lost to faults.

Premissa

Running the robot cannot do: stairs, terraces, crowded floors, big parties.

Premissa

Staff minutes per robot-hour beyond normal serving (loading, clearing paths).

Premissa

kWh per robot-hour.

Premissa

Electricity price per kWh (USD). Check your bill; energy is rarely a big line.

Finanças
Premissa

Annual financing / discount rate. Nobody publishes yours; 8% is a round mid-2026 commercial borrowing guess.

Premissa

Years in the NPV comparison.

Premissa

Share of a human service price that is labour (rises with wages). Used to escalate and to adjust US service prices to other countries.

Premissa

Share of a robot service price that is labour (pilot, technician). The rest is equipment, which learning curves make cheaper.

Premissa

Share of a lease or RaaS fee that pays for hardware (learns down). The rest is service and support (moves with wages).

What the spreadsheet misses

Segurança
Fewer heavy trays carried across a busy floor; robots are a trip hazard for guests who are not looking.
Qualidade
Hot food arrives at robot speed, which is not fast.
Flexibilidade
A runner also refills water, clears and charms.
Edge cases
Narrow aisles, steps, outdoor seating.
Customer experience
Novelty helps family restaurants and hurts fine dining.
Jobs and redeployment
Typical use is fewer runner shifts and servers spending more time at tables; tipped wages make the US maths odd (the BLS median includes tipped-wage states).
Regulamentação
None specific; food-hygiene rules apply to cleaning the trays.
