Introduction
A runtime claim says little without the workload. Standing still, walking, carrying a payload, running a large model and using dexterous hands can produce different power demand on the same robot.
Start with watt hours not marketing hours
Battery energy in watt hours provides a physical starting point. Runtime then depends on average system power. A robot with a larger battery may run longer while still being less efficient if its motors compute and power electronics consume more energy for the same useful work.
Use task energy for economic comparison
For repetitive work record the watt hours consumed per completed tote move pick or machine cycle. Include failed attempts because they consume energy without producing output. Energy per useful task connects electrical cost with productivity and can expose a robot that looks efficient only when failures are ignored.
Limitations and missing information
- No robot-specific battery discharge log or matched-workload comparison is available on this page.
Sources and methodology
IEC 62133-2:2017+AMD1:2021 concerns portable lithium battery safety, not an energy-efficiency benchmark. The Chinese pilot-platform project supplies no measured humanoid power traces. No comparative efficiency result is claimed here.
