This estimator calculates the daily field-task capacity of an agricultural robot fleet from effective area rate, operating time, productive utilization, and fleet size. It fits area-based operations such as mechanical weeding, spraying, mowing, scouting passes, or other tasks where completed hectares are a useful throughput measure.
Separating scheduled operating hours from productive utilization helps represent time lost to charging, turning, refilling, relocation, cleaning, supervision, short stops, or other routine interruptions. The effective area-rate input should already reflect task geometry and normal travel efficiency; the utilization adjustment then accounts for how much of the scheduled day is actually productive. The result is suited to workload and schedule planning, but field conditions, weather, crop accessibility, route conflicts, and agronomic timing can change real output from one day to the next.

1. Enter effective area rate Use the hectares one robot completes per productive hour for the specific field task.
2. Set daily operating hours Enter the scheduled hours available to each robot during the day.
3. Estimate productive utilization Use the percentage of scheduled time expected to produce actual field coverage.
4. Enter fleet size Count robots performing the same area-based task under comparable assumptions.
5. Review daily capacity Use the main result for fleet hectares per day and the breakdown for per-robot and seven-day capacity.
Productive hours per robot = Operating hours × Utilization
Area per robot per day = Effective area rate × Productive hours
Fleet daily capacity = Area per robot per day × Number of robots
Utilization is entered as a percentage and converted to a decimal. The weekly figure simply multiplies the estimated daily capacity by seven and assumes similar conditions each day.
What the result means
The main result estimates how many hectares the selected agricultural robot fleet can complete in one day.
If rainfall, crop condition, charging, refill logistics, or transport regularly interrupts work, use a lower utilization or measured effective area rate.
Given:
Effective area rate: 2.7 ha/hour
Operating hours: 11 hours/day
Productive utilization: 72%
Agricultural robots: 5
Calculation:
Productive hours per robot = 11 × 0.72 = 7.92 hours. Area per robot = 2.7 × 7.92 = 21.384 ha/day. Fleet capacity = 21.384 × 5 = 106.92 ha/day.
Result: About 106.9 hectares per day.
Interpretation: At these assumptions, the five-robot fleet could plan to complete roughly 107 hectares of the task during a typical operating day.
What is the difference between area rate and utilization?
Area rate describes hectares completed during productive work. Utilization describes the share of scheduled time that is actually productive, so the two inputs represent different kinds of efficiency.
Should turning time be included in area rate?
If your area rate comes from measured field performance, turning may already be included. If it is a theoretical straight-line rate, reduce it or use utilization to reflect realistic nonproductive time.
Can I use this for row-based tasks?
Yes if you can express the task as a reliable area rate. For operations better measured in row-kilometers, plants, or discrete actions, an area-based capacity model may be less informative.
Why might seven-day capacity be too optimistic?
The seven-day figure assumes the same daily conditions every day. Weather, maintenance, charging availability, labor support, and crop access can interrupt that pattern.
When should I use the fleet sizing calculator instead?
Use fleet sizing when the field area and deadline are fixed and you need the number of robots required. Use task capacity when robot count is already known and you want expected output.
