人員
U.S. Bureau of Labor Statistics

BLS OEWS May 2025 national median hourly wage, SOC 47-4011.

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).

價格
推算 HomeGuide

Midpoint of HomeGuide's traditional roof inspection $75-$200.

推算 HomeGuide

Midpoint of HomeGuide's standard visual drone inspection $150-$400. A drone company (AeroDeploy) quotes ladder inspections at $300-$800 instead: sources disagree.

機器人
假設

Inspections where someone still climbs (soft spots, interior attic checks).

假設

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

資金
假設

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

假設

Years in the NPV comparison.

假設

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

假設

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

假設

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

Cost per unit to 2035

Real terms (today's money). Robot hardware follows Wright's law; wages follow each country's history. Shaded band: robots-slow to robots-fast scenarios. Whirrwork 模型估算，並非事實。

What the spreadsheet misses

安全
Falls from roofs are a leading cause of construction deaths; steep or fragile roofs are where drones earn their fee.
品質
Drones capture every slope and thermal data; a person can feel soft decking.
彈性
Inspectors also check attics and gutters by hand.
Edge cases
Trees, power lines and no-fly zones near airports limit flights.
Customer experience
Photo reports help insurance claims.
Jobs and redeployment
Inspectors increasingly fly drones themselves: the human and robot are often the same person.
法規
Commercial drone pilots need FAA Part 107 (US) or local equivalent.
