What is a professional exoskeleton and how does it work?
Definition and basic principles
A professional exoskeleton is a wearable mechanical device that assists human body movements. Designed to be worn like technical clothing, it reduces muscle effort and joint strain during repetitive physical tasks or heavy manual handling. The main goal of exoskeletons at work is to prevent musculoskeletal disorders (MSDs), the leading cause of occupational illness in the UK.
- Two main categories exist: passive exoskeletons, which use springs, cables, or elastic bands to store and release energy without a motor, and active exoskeletons, equipped with motors and sensors that provide powered assistance.
- Target areas are primarily the back (for lifting and carrying loads), shoulders (for overhead work or arms raised), and upper limbs (for repetitive movements).
- A simple principle: the device redirects part of the effort to external structures, thereby relieving muscles and intervertebral discs.
Technology and ergonomics
The technologies embedded in modern exoskeletons are designed for discreet and effective integration into workers' daily routines. Ergonomics is a key factor in ensuring successful long-term adoption.
- Sensors and onboard intelligence: active models detect the angle and speed of movements in real-time, triggering assistance at the precise moment when effort is greatest.
- Lightweight and durable materials: carbon fibre, aluminium, and high-performance polymers keep the total weight often below 4 kg, even for the most comprehensive models.
- Adjustability: straps, harnesses, and joints are adjustable to fit different body shapes without hindering natural movements. Exoskeletons at work are designed to be worn for several consecutive hours without discomfort.
Key sectors for exoskeleton application
Logistics and warehousing
In warehouses and distribution centres, operators face repeated strain from lifting, carrying, and moving loads. Back and leg exoskeletons provide valuable assistance.
- Lifting assistance: devices reduce lumbar compression when lifting packages, even for moderate but repetitive loads.
- Fatigue reduction: operators maintain a steady pace for longer, reducing forced breaks and team rotations.
- Data insights: logistics companies report a 30 to 50% decrease in lower back pain after adopting exoskeletons, with a direct impact on absenteeism.
Manufacturing and assembly
Assembly lines, particularly in automotive and aerospace, impose demanding postures such as overhead work, repeated screwing, or welding at height. Shoulder exoskeletons are especially well-suited.
- Shoulder relief: specific models keep arms in a working position without excessive muscle effort, reducing tendonitis and neck pain.
- Quality improvement: a stable posture and less fatigue enable more precise movements, reducing defects and waste.
- Widespread adoption: manufacturers like Jaguar Land Rover and Airbus already use exoskeletons at work across several of their sites, with positive feedback from operators.
Construction and civil engineering
On construction sites, the demands are numerous: carrying heavy materials, working in crouched or bent positions, and exposure to the elements. Back and leg exoskeletons are the most common.
- Back protection: bricklayers, roofers, and tilers benefit from assistance when lifting cement bags, tiles, or slabs, reducing the risk of herniated discs.
- Enhanced durability: some models are designed to withstand dust, moisture, and impacts, meeting construction industry requirements.
- Prevention of chronic lower back pain: studies show that regular use of exoskeletons can reduce the incidence of lower back pain in construction workers by 40%.
Health benefits: a significant reduction in MSDs
Prevention mechanisms
Exoskeletons at work directly address the biomechanical causes of MSDs. By offloading stressed structures, they enable longer, damage-free work.
- Muscle offloading: electromyographic studies show a 40 to 60% decrease in back and shoulder muscle activity when using an exoskeleton.
- Neutral posture: the device naturally guides the body towards less stressful positions, limiting excessive twisting and bending.
- Reduction of peak strain: sensors continuously adjust assistance, avoiding the jerks that damage intervertebral discs.
Testimonials and data
Feedback from the field confirms the effectiveness of exoskeletons in preventing MSDs. Here are some concrete examples.
- Food processing plant: a Health & Safety manager observed a 50% drop in MSD-related leave within a year, with operators reporting 30% less fatigue at the end of the day.
- Logistics centre: after six months of use, lower back pain decreased by 70% among forklift drivers and order pickers.
- Social impact: workers feel more valued and motivated, improving morale and reducing staff turnover.
Impact on productivity and work quality
Measurable gains
Beyond health, exoskeletons at work have a direct impact on operational performance. The gains are quantifiable and often rapid.
- Reduced downtime: fewer forced breaks and team rotations are needed, increasing effective working time.
- Sustained pace: operators tire less quickly, maintaining a stable production rate throughout their shift.
- Improved quality: gesture precision increases, reducing manufacturing defects and waste. In automotive assembly, a 15% productivity increase has been observed.
Return on investment
The cost of a professional exoskeleton may seem high, but the return on investment (ROI) analysis is very favourable.
| Cost item | Estimated saving |
|---|---|
| MSD-related absenteeism | Up to 50% reduction |
| Staff turnover | Decrease of 20 to 30% |
| Productivity | Increase of 10 to 15% |
| Cost of an exoskeleton | £1,700 to £6,800 |
| Average ROI | Less than 12 months |
Exyvex solutions, for example, offer models tailored to each sector with personalised support to maximise effectiveness and accelerate the return on investment.
Safety standards and regulations in the UK
Legal framework
The use of exoskeletons at work is governed by strict regulations to ensure user safety.
- UKCA marking: following the UK's departure from the EU, exoskeletons are considered work equipment and must bear UKCA marking, demonstrating compliance with UK health and safety requirements.
- BS EN ISO 13482: this standard specifies safety requirements for exoskeletons classified as "service robots," including strength and reliability tests.
- Health and Safety at Work etc. Act 1974 (Section 2): employers must assess risks, provide training, and integrate the exoskeleton into their risk assessment procedures.
Financial support and grants
While exoskeletons are not reimbursed by the NHS, various support schemes exist to ease the investment.
- HSE and local grants: some regional bodies and industry-specific funds offer grants for purchasing exoskeletons as part of MSD prevention programmes.
- Regional development funds: several regions (e.g., Greater Manchester, West Midlands) provide direct support to SMEs for exoskeleton equipment.
- Exyvex support: the company helps its clients prepare funding applications and identify available grants.
