Design and Development of Prosthetic Hand Controlled by Wireless Gestures for Differently Able People

Abstract

This paper focuses on the design and development of Prosthetic hand to help differently-able people who lost their hands due to accidents and diseases. Our research purpose is to develop a master and slave robotic system that will be a substitute for the lost hand to do the day-to-day activities of a person. The person has to wear smart gloves in the hand to do gesture action. The gloves will able to transfer the hand gestures of differently-able people to react suitably and move the hand gripper (which contains spring coils similar to bones in human hand) based on the data from smart gloves. The methodology behind this research is that the analog signals produced in the flex sensor due to the gesture action are transferred to the servo motors to do a similar action in the 3D printed prosthetic hand through the Wi-Fi module. This research project involves two Arduino microcontrollers for communicating and controlling applications in both master and slave sections. A number of flex sensors are placed in the glove to get readings of the motion of human fingers and it is transmitted through the Wi-Fi module by using the Arduino microcontroller. The transmitted signals are received by the Wi-Fi module in the slave section through the Arduino microcontroller and further uses this signal to control various servo motors and it controls the slave robotic hand by using the ropes attached between the servo motor and 3D printed parts. Not only for differently-able people, but the enlarged model of this project can also be used in industries to handle hazardous, harmful, high temperatures and harmful things.
