Florida Atlantic University scientists have invented a unique robotic device to assist with the physical rehabilitation process of patients suffering from neurological damages to their upper extremities such as those due to stroke or Parkinson’s disease.

The invention is composed of motors, cables and spools enclosed within an acrylic case with a joystick that is indirectly connected to the system through magnetic attraction. This device is the first-known cable-driven robot to utilize a barrier between the operator and the moving mechanisms of the system.

The system does not contain any rigid parts that could suddenly harm or injure the user, and the device can be used in a physical therapy office or at home without supervision.
