Actuation and Fabrication of Human Inspired Artificial Hand

Multifarious tasks can be performed by a human hand such asgrasping, two or higher dimensional motions and various other daily life based manipulations. Here interest has been taken to analyse various artificial hands so as to develop one that could have the capability to perform motion in a plane, grasp an object for desired time interval and mimic various functions of a human hand. Hence, different articles and papers have been reviewed which gave an idea about its state of development and can also help emerging researchers in the field of rehabilitation robotics. This paper mainly focuses on some of the electrical actuator based biomimetic fingers, pneumatic actuator based artificial hand and Shape Memory Alloy(SMA) based artificial hand, their working principles and controlling process using various sensors.
