Robot Dwell Time at 11% i and o and settle allowance: a worked example

This worked example runs the robot dwell time numbers for a tougher week than the baseline: 11% i and o and settle allowance instead of the typical 15%. Estimate total robot dwell time per cycle from the number of dwell points, dwell completion rate, and an I/O and settle allowance.

The inputs for this scenario

  • Dwell and wait events per cycle: 8 events (held at the documented default)
  • Dwell completion rate: 30 events / min (held at the documented default)
  • I/O and settle allowance: 11 % (the input this scenario stresses; the baseline uses 15)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base robot dwell time = dwell and wait events per cycle / dwell completion rate.
  • Required robot dwell time works out to 0.3 sec at these inputs, and this is the headline figure for the scenario.
  • Base robot dwell time works out to 0.27 sec at these inputs.
  • I/O and settle allowance applied works out to 11 % at these inputs.
  • Dwell completion rate works out to 30 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where i and o and settle allowance sits at 15% and the headline result is 0.31 sec, this scenario comes in 3.48% below the baseline at 0.3 sec.
  • Use it when auditing a cycle for hidden dead time, or when validating that gripper, vacuum, and handshake waits fit inside the takt budget. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Required robot dwell time: 0.3 sec (headline result)
  • Base robot dwell time: 0.27 sec
  • I/O and settle allowance applied: 11 %
  • Dwell completion rate: 30 pieces / min
