로봇일까, 사람일까?

Warehouse order picking (AMR-assisted)

Picker walking with a cart vs Collaborative picking AMRs (people still pick)

On these numbers it is close: decide on the things that are not cost. Even running flat out, one robot would not displace enough work to pay for itself.

작업량

Order lines picked per day.

Operating hours per day (two shifts).

가정

Operating days per month.

가정

Active months per year.

U.S. Bureau of Labor Statistics

BLS OEWS May 2025 national median hourly wage, SOC 53-7065.

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).

가정

Picks per hour for a person walking a cart. Varies hugely with order profile; use your own WMS figure.

로봇
가정

Picks per robot-hour. Collaborative AMRs do the walking; people still do the picking, so this is robot throughput, not autonomy.

CIVL

Reported Locus Robotics RaaS price per robot per month.

가정

WMS integration, mapping and change management for a first site. Integration often costs more than the robots.

가정

Contract or useful life in years.

가정

Share of the shift each robot is available.

가정

Share of robot work lost to faults.

가정

Share of picks that stay manual (oversize, hazmat, rush orders).

가정

Picker minutes per robot-hour. In assisted picking a person meets the robot at each pick face, so this is large by design.

가정

kWh per robot-hour.

가정

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

자금
가정

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

가정

Years in the NPV comparison.

가정

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

가정

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

가정

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. Whirrwork의 모델 추정치이며 사실이 아닙니다.

What the spreadsheet misses

안전
Less walking and pushing; mixed robot and forklift traffic needs rules.
품질
Fewer mis-picks are commonly reported because the robot screen shows the next pick; measure yours.
유연성
RaaS lets you add robots for peak and hand them back, which is the main argument for it.
Edge cases
Oversize items, very low volumes and constantly changing slotting reduce the benefit.
Customer experience
Invisible to customers except via speed and accuracy.
Jobs and redeployment
Assisted picking keeps people picking; it changes the job (less walking) more than it removes it.
규제
Workplace safety rules for mobile robots (ISO 3691-4 in many markets) apply to the vendor and the site.
