Quick answer. A practical model for evaluating passive and active exosuits in fulfillment operations, including the utilisation assumptions that usually break the case.
Warehouse exoskeleton business cases usually start with a unit price and a productivity assumption. Both are weak foundations. The stronger model starts with the exposure you are trying to change and the adoption rate you can realistically sustain.
Count the workers who perform the target task for a meaningful share of their shift. Then subtract those who cannot wear the device for medical, fit or clothing reasons. The result is the addressable population, not the site headcount.
Assistance only exists while the device is worn. Estimate wear time from comparable deployments, not from the theoretical shift length. A passive exosuit with a 60% wear rate may deliver more cumulative support than a powered system that is removed after two hours.
Use a biomechanical or ergonomic measure that your EHS team already tracks. If the device reduces peak lumbar flexion during a defined lift, record the change. Do not convert a marketing assistance rating directly into injury reduction.
Include fitting, training, replacement parts, cleaning, charging, service and the management overhead of a mixed fleet. For subscription models, include the exit cost and the minimum term.
Run the model with wear time and addressable population reduced by 30%. If the case depends on near-perfect adoption, it is a pilot hypothesis. That is useful — as long as it is labelled as one.
ROI is not the same as injury avoidance. A device can improve perceived exertion without reducing claims, or reduce claims in one task while shifting load elsewhere. Track leading indicators and adverse events alongside the financial model.
Compare candidate systems in our comparison tool, and treat any missing runtime, weight or certification value as a pilot risk.
An exoskeleton analysis is only useful if it changes what a buyer does next. The purpose of a dossier is not to declare a winner in the abstract, but to make the next conversation more specific: which task, which users, which environment, which constraints and which evidence is still missing.
The first step is to translate the task into a written requirement. Describe the posture, load, repetition, duration, reach height, floor surface and clothing. Add the practical constraints that decide adoption: donning time, heat, tool clearance, cleaning and storage. A system that performs well in a demonstration but interferes with the actual workflow will not be worn after the pilot team leaves.
The second step is to separate the system from the deployment. A device can be well engineered and still fail because the service network is thin, the training is inadequate or the spare-parts lead time is measured in months. Ask for the service model in writing, including response time, replacement units and the cost of consumables.
Data quality should be scored explicitly. A dossier that publishes weight, runtime, user limits and certification scope is easier to pilot than one that leaves those values unknown. Missing values are not automatically disqualifying, but they are a cost: someone has to resolve them before a purchase order, and that work belongs in the project plan.
Use the product index to narrow the field by category, drive type, weight, runtime and region. Treat the filters as a way to structure the question, not as a substitute for reading the parameter states. A system that disappears from a weight band because its weight is not disclosed is telling you something about the dossier.
Place the shortlisted systems side by side in the comparison tool and focus on the rows where they diverge. Differences are useful; similarities are useful too. If two systems are identical on the parameters that matter, the decision may turn on service, fit or commercial terms rather than engineering.
Check the manufacturer profile for verification level, product line and company documentation. A maker with a clear primary source for each claim is easier to audit than one whose brochure is the only available reference. Where a claim matters to safety, ask for the declaration of conformity and the technical file summary.
Finally, write the brief. Include the task, environment, user profile, deployment volume, region and budget range. A good brief lets the research desk separate sourced values from open questions, so the next conversation starts with evidence rather than a demonstration.
Training is part of the system, not an afterthought. Ask who delivers the first session, how competency is assessed and what happens when a new operator joins the team. A device that requires a specialist to fit it every morning has a different operating cost from one that a trained supervisor can deploy independently.
Keep a decision log beside the shortlist. Record what was verified, what was assumed and who owns each open question. When the recommendation goes to a capital committee, the log is often more persuasive than another product demonstration because it shows exactly which risks have been retired.
Send the requirement when the shortlist is ready. The response should make the gaps visible, not hide them behind a polished recommendation. That is the standard this index is built to support.
Start with the intended use, the certification scope and the service model. Those three items decide whether a system can be deployed, not just demonstrated.
No. Published parameters support shortlisting, but fit, comfort, training quality and local service response require a structured evaluation with the intended users.
Missing values are recorded as Unknown or Not disclosed and are never inferred from a similar product. Each dossier shows the date of the last update and links to its primary sources.
