This estimator calculates how many repeatable task cycles a collaborative robot fleet can complete during a scheduled shift. It is useful for cells where cobots handle tending, fastening, pick-and-place, inspection, packaging, or another cycle-based operation and the team needs a quick capacity check before changing staffing or equipment assumptions.
The estimate separates scheduled time from productive utilization, so breaks, changeovers, brief stops, and other losses can be represented without changing the underlying cycle time. The result is best used for scenario planning: compare different cycle times, shift lengths, utilization rates, or robot counts to see which variable has the strongest effect on throughput. It is not a guarantee of production because actual output can also be constrained by upstream material availability, human interaction, safety stops, quality holds, and downstream bottlenecks.

1. Enter the cycle time Use the average elapsed minutes required for one complete cobot task cycle.
2. Set the shift length Enter the scheduled operating hours for the shift being evaluated.
3. Estimate productive utilization Use the share of scheduled time when the cobot is actually available to run cycles.
4. Enter the robot count Count only cobots assigned to the same repeatable workload and operating under similar assumptions.
5. Review capacity Read total fleet cycles first, then compare per-robot cycles and productive minutes in the breakdown.
Productive minutes per robot = Shift hours × 60 × Utilization
Cycles per robot = Productive minutes ÷ Cycle time
Fleet task capacity = Cycles per robot × Number of robots
Utilization is entered as a percentage and converted to a decimal in the calculation. The model assumes each robot has the same cycle time and utilization and that cycles are independent enough to scale approximately with robot count.
What the result means
The main result is the estimated number of complete task cycles the selected cobot fleet can perform in one shift under the entered assumptions.
Use a measured average cycle time and realistic utilization for planning; small stops and shared human work can make real output lower than the theoretical estimate.
Interpretation: Under these assumptions, the three-cobot cell can plan around roughly 337 full cycles before considering additional line constraints.
Should cycle time include loading and unloading?
Include every step that must occur before the next identical cycle can begin. If a person performs loading or unloading and the robot must wait for it, that waiting time belongs in the effective cycle time or utilization assumption.
What utilization percentage should I enter?
Use measured productive runtime divided by scheduled time when possible. Avoid using 100% unless the process truly has no planned or unplanned losses during the period.
Why can actual output be lower than this estimate?
The calculation does not model blocked stations, starving, quality rework, tool changes, material shortages, or synchronization with other equipment. Any of those can reduce completed cycles.
Can I use different robot speeds in one calculation?
This page assumes one common cycle time. For robots with materially different cycle times, estimate each group separately and add the resulting capacities.
How is task capacity different from fleet sizing?
Task capacity starts with a known robot count and estimates output. Fleet sizing starts with a required workload and estimates how many robots are needed to meet it.
