The goal of this project was to create a device to reduce the magnitude of hand tremors in individuals with Parkinson’s disease or Essential Tremor. We focused primarily on tremors that caused the hand to rotate about a central oscillator parallel to the forearm. We utilized the physical properties of a spinning gyroscope to act as the stabilization mechanism and dampen the tremor effects experienced by the individual. Our final prototype uses a small electric motor to spin a gyroscope on a swinging cradle. This allows the gyroscope to naturally precess due to an input torque and generate a counter torque along the axis of the hand’s rotation. To monitor the device, we incorporated an RPM sensor in conjunction with an Arduino to receive sensory information about the gyroscope.
