Hand tremor is a neurological disorder that affects people with Parkinson's disease and elderly affecting day to day activities. Hand vibration is a rhythmic muscle movement that occurs due to disorder in the motor system of human body. There are no permanent treatment options available. The subjects typically do life style modifications to cope up with the disease. In this work, we propose a wearable auto stabilizing cup holder that helps in performance the routine activities such as drinking water etc. The proposed system uses Inertial measurement unit (IMU) sensor and actuators for stabilizing the cup when under severe hand vibration. Dynamic modelling of the system is performed including slosh dynamics. A PID controller performance under disturbance and Cross-coupling effect has been analyzed. The prototype design is implemented using solid works and the controller simulation is performed using MATLAB Simulink. Initial tests show satisfactory performance of the system.
