A method for calculating service robot ROI

Calculate service robot return by measuring your own venue before deployment and comparing afterwards. Count the trips somebody currently makes, time a representative one, and note how often that person is interrupted to do it. Those three numbers are the baseline every later figure must be measured against to mean anything.

Why this page has no calculator

Because an ROI calculator on a vendor's website is a persuasion device. It takes your inputs, applies assumptions you cannot see, and produces a number designed to be encouraging. You cannot audit it and neither can your finance team.

What follows instead is a method you run yourself, on your own floor, before anybody quotes you anything.

Step one: count the trips

Pick the specific job you want a robot to do. Not "help in the restaurant" — "carry plates from the pass to tables in the main room".

For one week, count how many times somebody makes that trip per shift. A tally on a sheet by the pass is enough. Precision matters less than doing it at all.

Step two: time a representative trip

Door to door, including the waiting. From picking up to being free again.

Time several across different periods, because a quiet Tuesday and a full Saturday are different measurements, and the busy one is the one that matters.

Step three: count the interruptions

This is the number nobody records and it is usually the largest.

How often was the person making that trip pulled off something else to do it? What were they doing? A server abandoning a table to carry plates has a cost that never appears in a labour calculation, and it is frequently the real reason a venue is considering a robot in the first place.

What you now have

Three numbers: trips per shift, minutes per trip, interruptions per shift. That is the baseline, and it is worth more than any vendor projection because it describes your venue.

It also frequently changes the decision before a purchase happens. Venues that do this sometimes discover the trip is four metres and infrequent, at which point a robot is not the answer and everyone has been saved some money.

Step four: compare afterwards

After deployment, Hybot records per robot: completed tasks and distance travelled, daily and lifetime, visible in fleet management. These are counters kept by the system.

Compare tasks completed against your trips-per-shift baseline. Compare distance against trips multiplied by trip length. Then ask the staff the third question again: are you still being pulled off things?

What we will not give you

A payback period. It depends on your baseline, your labour cost, your unit count and your venue layout — and a generic figure would be a number we invented. Tell us about the venue and the conversation can be specific.

Frequently asked questions

Why take a baseline before buying?

Because without one, every number afterwards is unanchored. A fleet that completed four hundred tasks in a week sounds impressive and means nothing until you know how many trips your staff were making before. The measurement costs a fortnight of noticing and no money.

What should I measure?

Trips per shift for the job you want automated, minutes per representative trip including any waiting, and how often the person doing it was pulled away from something else. The third is usually the largest hidden cost and the one nobody records.

What can the platform tell me afterwards?

Hybot records completed tasks and distance travelled per robot, both daily and lifetime. Those are counters kept by the system rather than estimates, so the post-deployment side of the comparison is measured on your floor rather than modelled from another venue's results.
