Robot Payload Utilization at 54% target payload utilization ceiling: a worked example

Suppose target payload utilization ceiling falls to 54%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate how much rated robot payload the part plus EOAT use at the tool center point, with a gap to your design margin target.

The inputs for this scenario

  • Combined load at the TCP (part + gripper/EOAT): 18 lb (held at the documented default)
  • Rated robot payload: 25 lb (held at the documented default)
  • Target payload utilization ceiling: 54 % (the input this scenario stresses; the baseline uses 75)

Working through the calculation

  • The calculation starts from the formula this tool documents: Robot payload utilization = combined load at TCP / rated robot payload.
  • Robot payload utilization works out to 72 % of rated payload at these inputs, and this is the headline figure for the scenario.
  • Payload margin gap works out to -18 points at these inputs.
  • Combined load at TCP works out to 18 value at these inputs.
  • Rated robot payload works out to 25 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target payload utilization ceiling sits at 75% and the headline result is 72 % of rated payload, this scenario lands almost exactly on the baseline at 72 % of rated payload.
  • It computes payload utilization as combined TCP load divided by rated payload, plus the point gap between that and your target ceiling. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Robot payload utilization: 72 % of rated payload (headline result)
  • Payload margin gap: -18 points
  • Combined load at TCP: 18 value
  • Rated robot payload: 25 value
