Robotic End-of-Arm Tooling worked example

Payload Derating with eoat + robot connected load during derated cycle of 6 kW: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop eoat + robot connected load during derated cycle to 6 kW, then walk the calculation through step by step. Estimate payload derating for robotic end-of-arm tooling using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • EOAT + robot connected load during derated cycle: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Derated-cycle runtime: 8 hr (held at the documented default)
  • Blended plant electricity rate: 0.12 $ / kWh (held at the documented default)
  • Parts handled during runtime: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total payload derating energy cost = payload derating connected load × payload derating runtime × blended electricity rate.
  • Payload derating energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total payload derating energy cost works out to 5.76 $ at these inputs.
  • Energy cost per kWh works out to 0.01 $ / piece at these inputs.
  • Hourly payload derating energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where eoat + robot connected load during derated cycle sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to eoat + robot connected load during derated cycle, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a constant connected load; real derated cycles have peak-acceleration current spikes and idle dwell that a single average kW figure smooths over.

Results at a glance

  • Payload derating energy used: 48 kWh (headline result)
  • Total payload derating energy cost: 5.76 $
  • Energy cost per kWh: 0.01 $ / piece
  • Hourly payload derating energy cost: 0.72 $ / hr
