Industrial Exoskeletons

Back and shoulder designs compared

Back-support exoskeletons aim to share the load when you bend and lift, while shoulder exoskeletons hold up raised arms during overhead tasks such as drilling or fitting. Each type can be passive, using springs or elastic elements, or active, using motors. A 2021 systematic review in Frontiers in Bioengineering and Biotechnology by Ali and colleagues covered 34 back-support exoskeletons, 16 passive and 18 active, and reported reductions in measured back muscle activity that varied widely between devices and tasks. Workplace designs listed on this site include the Laevo Back Exoskeleton at $2,500 and the Levitate Airframe at $4,500 in October 2026, while the Sarcos Guardian XO was listed at $100,000.

What the evidence does and does not show

A 2022 evidence-mapping review in Applied Ergonomics by De Bock and colleagues analysed 139 studies of occupational exoskeletons. Only 22 were field studies in real workplaces, and only 19 per cent recruited actual workers; most relied on younger convenience samples, and men outnumbered women by roughly five to one. Electromyography, which records muscle activity, was the most common measure. A device that lowers muscle activity during a short laboratory task has therefore not necessarily been shown to prevent musculoskeletal disorders over years of shifts. Ali and colleagues likewise concluded that technical challenges and a lack of established safety standards limit wider adoption in industry. Ask makers which kind of study supports each claim.

Fit, comfort and who gets left out

Because most research volunteers were young men, published comfort results may say little about how a device suits older or female workers. Pressure points, heat under pads and restricted movement when climbing, kneeling or driving can all decide whether people keep a device on. Ali and colleagues also found discomfort at other body sites with some designs, including the knees for one passive back device, a reminder that load tends to move rather than disappear. Ask whether the device can be removed quickly in an emergency, whether it fits over the protective clothing your site requires, and how straps and pads are cleaned or replaced when several people share a unit.

Running a trial your workers trust

Choose one task with a clear physical demand, such as handling boxes at a fixed height or drilling into a ceiling, and agree the measures before anyone puts a device on. Useful measures include discomfort ratings by body region, task time, errors and how often people choose to wear the device when it is optional. Involve worker representatives in planning, keep wear voluntary during the trial and record the reasons people stop. Afterwards, compare the results with other controls such as lifting aids, better work heights or job rotation, since an exoskeleton should complement those measures rather than replace them. Decide in advance what result would justify buying more units.

Common questions

How long does it take to get used to an exoskeleton?

It varies by device and person. Early sessions often feel unusual, so plan a familiarisation period with short wear times, and judge the device only after workers have used it on real tasks over several shifts rather than during a first demonstration.

Can one exoskeleton be shared between workers?

Often, but sharing raises fit and hygiene questions. Readjust straps for each person, use washable or individual liners where the maker offers them, and record who wore which unit so that discomfort reports can be traced back to fit.
