¿Robot o humano?

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.

Carga de trabajo

Order lines picked per day.

Supuesto

Operating hours per day (two shifts).

Supuesto

Operating days per month.

Supuesto

Active months per year.

Personal
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).

Supuesto

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

Robot
Supuesto

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.

Supuesto

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

Supuesto

Contract or useful life in years.

Supuesto

Share of the shift each robot is available.

Supuesto

Share of robot work lost to faults.

Supuesto

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

Supuesto

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

Supuesto

kWh per robot-hour.

Supuesto

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

Finanzas
Supuesto

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

Supuesto

Years in the NPV comparison.

Supuesto

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

Supuesto

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

Supuesto

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

Seguridad
Less walking and pushing; mixed robot and forklift traffic needs rules.
Calidad
Fewer mis-picks are commonly reported because the robot screen shows the next pick; measure yours.
Flexibilidad
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.
Regulación
Workplace safety rules for mobile robots (ISO 3691-4 in many markets) apply to the vendor and the site.
