Our Rehabilitation Exoskeleton Platrorms
Harmony: Shoulder and Arm Exoskeleton
Harmony is an upper body exoskeleton whose development commenced in 2011 as a platform for stroke rehabilitation focussed on the shoulder. Its novel mechanisms track the complex human shoulder joint as well as the scapular movement of the shoulder girdle. Moving coaxially with the user's skeletal structure, Harmony maximizes the available range of motion of the human shoulder and shoulder girdle while ensuring safety with both physical and programmed interlocks. Our advanced actuator and controller technology allow Harmony to customize gravity compensation, assistance, and impedance as needed for the patient. This assist-as-needed paradigm encourages the active participation of patients. With 14 active degrees-of-freedom, Harmony powers the movement of both arms and can thus also provide bimanual therapy, which is developed based on the neurological coupling between left and right halves of the human nervous system.
Harmony is the first ever rehabilitation robot capable of powering movements of both sides of the body, allowing novel therapy techniques involving both the healthy and stroke affected sides of the patient’s body.
Responding to the patient progress is a critical feature in therapy. Our advanced sensing and actuation technology provide ‘just the right amount’ of assistance to challenge users, while still enabling them to complete the exercises
ANATOMICALLY MATCHED SHOULDER DESIGN
With a 5 Degree-of-freedom shoulder joint, Harmony is the only rehabilitation robot today that can completely track the human shoulder’s anatomy, thus ensuring scapulohumeral rhythm (SHR).
Maestro: Hand Exoskeleton
Development of the Maestro hand exoskeleton began in 2012 as a single finger module for therapy focussed spinal cord injury. Maestro has since evolved into a functional hand exoskeleton that consists of a thumb, index, and middle finger modules. Mechanically and electrically robust, accurate in sensing and torque-actuation, and compatible with various rehabilitation schemes, Maestro is fabricated using SLS 3D printed technology over a lightweight aluminium core frame. Bowden cable actuation enables the exoskeleton to be extremely lightweight at just a few hundred grams.
The Maestro platform has successfully been used for a wide array of research topics including: adaptive control theories for hands movement, the study of human motor learning, novel rehabilitation frameworks, progress of hand muscle fatigue, and EMG based intention recognition for assistance for spinal cord injury patients.
Harmonic Bionics : About us
Harmonic Bionics was founded in 2016 as a spin-off of ReNeu Robotics Lab at The Univ. of Texas at Austin. We are actively developing rehabilitation robotics platforms for introduction into the clinical market, and we aim to revolutionize the fields of therapy for stroke and spinal cord injury. Our exoskeleton platforms are already being tested in pilot clinical trials and are well known in the rehabilitation robotics research community. The mission of Harmonic Bionics is to innovate the rehabilitation process with robotic technology to grant all stroke and spinal cord injury survivors an improved quality of life.
