Quick answer. Three passive shoulder systems, three approaches to overhead work. How to compare support profile, fit and certification.
Passive shoulder exoskeletons all promise to reduce arm fatigue during overhead work. The differences that matter in procurement are support profile, interference with tools, fit range, certification and the quality of the technical file.
MATE-XT is a passive upper-limb system from Comau, a large automation group. It benefits from an established industrial support network and a relatively complete public dossier. The trade-off is a frame-based design that may interfere with tight workspaces.
Skelex 360 is a lightweight passive shoulder exoskeleton designed for sustained overhead work. It is fit-sensitive and works best when the task involves arm elevation rather than heavy lifting.
AIRFRAME uses a mechanical support structure to offload the shoulders. The concept is clear, but public technical detail is limited, which raises the due-diligence burden.
Two devices can weigh the same and feel completely different because the assistance curve varies with arm angle. Ask for the support profile across the working range, and trial the device on the actual task with the actual tools.
Use the comparison tool to place them side by side, then request the missing values directly. For a broader view of industrial systems, see the industrial category.
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.
