Rex Bionics :: Robotic Exoskeletons That Enable Rehabilitation, Standing, Walking & Functional Exercise

Rex Bionics is a New Zealand-based medical robotics company focused on developing advanced robotic exoskeletons that enable rehabilitation, standing, walking, and functional exercise for people with severe mobility impairments. The company’s flagship product is the REX, a self-balancing, hands-free robotic exoskeleton designed specifically for individuals with neurological conditions such as spinal cord injury, multiple sclerosis, stroke, and traumatic brain injury.

REX stands alone without crutches or walking frames, using 10 custom linear actuators and advanced control software to provide stable, autonomous movement. Users can perform forwards, backwards, sideways, and turning motions, as well as a range of therapeutic exercises called REXERCISES (including squats, lunges, sit-to-stand, leg swings, and stretches). The system supports users up to 100 kg, is adjustable within minutes, and allows quick transitions between patients in clinical settings. Powered by interchangeable lithium-polymer batteries, it provides approximately 60 minutes of use per charge.

The robot is intended for supervised clinical use in rehabilitation centers and hospitals. It reduces physical strain on therapists while delivering consistent, repeatable therapy. Clinical applications include improving circulation, reducing muscle spasms, enhancing sleep quality, and supporting overall physical and mental well-being through increased standing and movement time. Rex Bionics has conducted trials in the UK, US, Australia, New Zealand, and the Middle East, with the device registered in the US for professional supervision.

By offering fully autonomous control that most users master in their first session, Rex Bionics addresses the limitations of other exoskeletons that require upper-body strength for crutches. The technology combines robust mechanical engineering with proprietary software to create a safe, accessible platform that supports both rehabilitation goals and activities of daily living.
