Gesture Controlled Robotic Hand Prosthesis for Upper Limb Amputee Rehabilitation

In this work, a low cost, light weight, gesture controlled robotic hand prosthesis is designed and developed to enhance user experience in upper limb rehabilitation. The existing hand prosthetic products available in the market are economically expensive and are not often customizable to the patient needs. The proposed system utilizes two main components: controller component and an actuator component. The controller component consists of data glove embedded with flex sensors to acquire the hand movements of the patient. The Arduino UNO microcontroller acts as an interface between the controller and actuator components. The robotic hand is designed using Creo CAD software and is developed with ABS material using 3D printing technology. The robotic hand has 2-Degrees of Freedom (DoF) and could be able to mimic the movements of the hand signals obtained using the data glove. Results show that this system could enable the upper limb amputees to perform the activities of daily living at ease. Thus, this gesture-controlled hand prosthetic could aid the physiotherapists and clinicians to provide better rehabilitation to the upper limb amputees at an affordable cost.
