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.
What Ottobock is
Ottobock (Alfred Ottobock Healthcare GmbH, known as Ottobock SE and Co. KGaA after its restructuring) is a German prosthetics and orthotics company founded in 1919 in Duderstadt, Germany. Ottobock is the global leader in prosthetics by revenue, best known for prosthetic limbs and orthotics for amputees and people with mobility impairments. The company expanded into industrial exoskeletons through its Paexo product line and the acquisition of SuitX in 2021.
Paexo industrial exoskeletons
The Paexo series targets industrial workers in manufacturing, logistics, automotive assembly, and construction who perform repetitive physically demanding tasks.
Paexo Shoulder provides mechanical support to the arms and shoulders during overhead work. It uses spring mechanisms to offset the weight of raised arms, reducing the shoulder fatigue associated with prolonged overhead assembly, maintenance, and painting tasks. Paexo Shoulder is a passive (unpowered) device.
Paexo Trunk targets the lower back during lifting and bending tasks. It uses elastic bands and a rigid frame to redistribute load from the lumbar spine, reducing the injury risk from repeated bending and lifting. Also passive.
Paexo Cervical supports the neck during prolonged downward-looking tasks (inspection of vehicle undersides, floor-level assembly). It provides spring-based neck support to reduce fatigue.
Paexo devices are passive (unpowered) exoskeletons in all current configurations. They provide mechanical force redistribution rather than powered actuator assistance. This makes them lighter, simpler, and cheaper than active powered exoskeletons like Guardian XO but provides less force amplification.
SuitX acquisition in 2021
Ottobock acquired SuitX, a US-based industrial and medical exoskeleton company, in 2021. SuitX had developed both passive industrial exoskeletons and a medical lower-limb powered exoskeleton (the Phoenix). Post-acquisition, the SuitX product line has been integrated into Ottobock's broader exoskeleton portfolio.

Frequently asked questions
- Is Ottobock a robot company?
Ottobock is primarily a prosthetics and orthotics company. Its exoskeleton products (Paexo series) are a secondary product line. The company's core business is prosthetic limbs and orthotics for amputees and people with mobility conditions. Exoskeletons are an adjacent product category enabled by Ottobock's mechanical engineering expertise in wearable force-assistance devices.
- What does Paexo Shoulder do?
Paexo Shoulder provides spring-based mechanical support to the arms and shoulders during overhead work. Workers in automotive assembly, aircraft maintenance, painting, and similar tasks who hold their arms raised for extended periods experience significant shoulder fatigue. Paexo Shoulder offsets the weight of raised arms using springs, reducing the load on shoulder muscles during sustained overhead postures.
- Are Paexo exoskeletons powered?
No. All current Paexo models are passive, meaning they use springs and elastic bands to redistribute force without any electrical power source. They do not have motors or actuators. This makes them lighter and simpler than active powered exoskeletons like Sarcos Guardian XO, but they provide mechanical support rather than active strength amplification.
- What happened to SuitX after Ottobock acquired it?
Ottobock acquired SuitX in 2021. SuitX had developed both industrial passive exoskeletons and the Phoenix powered lower-limb medical exoskeleton. Post-acquisition, the SuitX product line has been integrated into Ottobock's broader exoskeleton portfolio. The specific ongoing product development and branding under Ottobock requires current product catalog verification.
- Is Ottobock publicly traded?
Ottobock SE and Co. KGaA is a privately held German company as of mid-2026. The company is not listed on a public exchange. Ottobock reports revenue figures voluntarily but is not subject to the public disclosure requirements of listed companies.
- How does Paexo compare to Sarcos Guardian XO?
Paexo (passive, no power) and Guardian XO (active, powered) are at opposite ends of the industrial exoskeleton technology spectrum. Paexo uses springs and elastic bands for mechanical support; Guardian XO uses electric actuators for powered strength amplification. Paexo is lighter, simpler, and lower-cost; Guardian XO provides greater force amplification. The right choice depends on the task: Paexo for sustained posture support; Guardian XO for heavy lifting and carrying.
