Cost Effective Self-stabilizing Smart Hand Held Platform (spoon/pen) For Elderly Or Parkinson's Disease Patients
Project Description :

This work deals with development of cost an effective self stabilizing smart platform (spoon/pen) for bringing stability to the hands of elderly persons or for patients with parkinson’s disease using mems tri-axial accelerometer. the developed prototype introduces an easy to adopt hand mount device that can be used to support the tremors in hands of old people or in persons with the said disease for day to day normal activities like writing with a pen, having food with a spoon and also holding crockery/knifes. the designed system is build around an 8-bit avr microcontroller along with a 6 dof (degree of freedom) tri-axis imu (inertial measurement unit) in a form of hand held hardware. the person’s hand tremors are read by the system in form of acceleration data which is fetched from the imu and then are made to go through an embedded kalman filter which performs estimation on the data acquired from the acceleration sensor. in order to drive the system a custom designed electromagnetic (a servo) drive is designed to work with an embedded micro-controller based application. every time there is a change in acceleration data the servo is actuated in a direction opposite to the recorded value from the person’s hand tremor. this device uses six-point based sensor data calibration to eliminate discrepancies in senor output due to zero-g and installation errors.
