Methodology

How the dataset is built

Runtime is stored in minutes, while original battery capacity units remain unchanged. Walking, standing, standby, base-only and combined-runtime claims are labelled separately and are not averaged.

Editorial analysis

Thirteen records cover different kinds of operation

The sample includes bipeds, a mobile base and robots with replaceable batteries. Some records provide a runtime interval while others publish battery capacity without a corresponding endurance figure. A missing runtime does not mean zero operating time.

Capacity and endurance are separate measurements

Ampere-hours describe charge capacity and require voltage to compare stored energy. Watt-hours describe energy more directly. Neither specifies endurance without knowing power consumption during the task. Standing, walking and repeated lifting can therefore produce different runtimes from the same battery.

Swapping changes the operating plan

A replaceable battery can reduce charging interruptions, but the table does not establish the time or staffing needed for every swap. Estimate a shift using active duty, charging, replacement and maintenance periods rather than multiplying a headline runtime.

Frequently asked questions

Can the longest listed runtime identify the most efficient robot?

No. The records use different workloads and may describe a mobile base rather than a complete humanoid system.
