Exoskeletons
Powered wearable robotic devices that assist or amplify human movement. Exoskeletons are not autonomous robots: the wearer's intent drives every action. Medical clearance (FDA, CE) is the verification gate for clinical use; industrial exoskeletons target worker fatigue and injury reduction.

The exoskeleton category requires a mandatory editorial clarification: exoskeletons are not autonomous robots. They are human-in-the-loop powered wearable devices. The wearer's intent drives every action the exoskeleton executes; the device amplifies, assists, or enables human movement but does not navigate, plan routes, or operate independently. This distinction applies uniformly across all products in this cluster regardless of how sophisticated the control system is.
The primary structural axis is medical vs industrial. Medical exoskeletons are regulated devices requiring FDA clearance in the US or CE marking in Europe, prescribed by physicians, used in clinical rehabilitation or by individual patients with specific mobility impairments (spinal cord injury, stroke, multiple sclerosis). Industrial exoskeletons are workplace safety and productivity devices used by workers to reduce fatigue from lifting, bending, and overhead work; they do not require medical-device regulatory clearance. The two sub-cohorts have entirely different regulatory environments, distribution channels, pricing, and customer relationships.
Medical exoskeletons include Ekso Bionics EksoNR (FDA-cleared for stroke and spinal cord injury rehabilitation), ReWalk Robotics ReWalk (FDA-cleared for personal home use in spinal cord injury), and Cyberdyne HAL (approved in Japan and EU, uses bio-electrical signal reading for intent detection). The medical verification anchor is regulatory clearance status plus published clinical trial outcomes.
Industrial exoskeletons include Sarcos Robotics Guardian XO (full-body powered strength amplification), Ottobock Paexo (passive and active series for manufacturing and logistics workers), and a broad ecosystem of passive and unpowered soft-exoskeleton products. Industrial exoskeletons do not have regulatory clearance requirements in most jurisdictions; they are evaluated on ergonomic and safety outcomes in worker populations.

Adjacent clusters
- AI wearables: AI wearables and exoskeletons share the worn-by-human form but differ structurally: AI wearables (smart glasses, AI earbuds) are information and interface devices; exoskeletons are physical force and mobility augmentation devices. Both are human-in-the-loop rather than autonomous.
- Humanoid robots: Exoskeletons and humanoid robots are both bipedal physical AI systems but are opposite in the autonomy dimension: exoskeletons require a human operator inside them and amplify human capability; humanoid robots operate autonomously without a human inside.

What is an exoskeleton robot and how does it work?
An exoskeleton is a powered wearable robotic device worn by a human that assists or amplifies the wearer's movement. Exoskeletons are not autonomous robots: the wearer's intent drives every action. The category divides between medical exoskeletons (FDA-cleared for rehabilitation and personal mobility) and industrial exoskeletons (worn by workers to reduce fatigue and injury risk).

Medical exoskeletons
Medical exoskeletons are regulated devices requiring FDA clearance (US) or CE marking (EU) for clinical or personal use. Applications include rehabilitation after stroke, spinal cord injury, and MS, and personal mobility for paraplegic users. FDA clearance date and clinical trial outcomes are the primary verification anchors.

Industrial exoskeletons
Industrial exoskeletons are worn by workers to reduce fatigue and injury risk in physically demanding tasks: lifting, overhead work, bending, and prolonged standing. Regulatory clearance is not required in most jurisdictions. Worker ergonomic outcome studies and injury-rate data are the verification anchors.
What is Sarcos Guardian XO and how does it work?
Sarcos Robotics makes the Guardian XO, a full-body industrial powered exoskeleton that amplifies the wearer's lifting and carrying capability. Guardian XO is designed for heavy industrial work requiring prolonged lifting of significant weight. Sarcos Robotics was founded in 1990 in Salt Lake City, Utah.
What is Ottobock Paexo and how does it help workers?
Ottobock is a German prosthetics and orthotics leader that makes the Paexo series of industrial exoskeletons for manufacturing and logistics workers. Paexo models target overhead work (Paexo Shoulder), lower back strain (Paexo Trunk), and neck fatigue (Paexo Cervical). Ottobock also acquired SuitX in 2021. The company is a privately held German firm.
