Robotic Hands a Base for Prosthetics - A Review

Abstract

This review paper reports the findings of previously designed robotic hand and summarizes the advantages and limitations for modeling a robotic hand and proposes methods to overcome the limitations of the previously designed hand models. A robotic hand forms its base by mimicking the structure and motions of a Human hand and all studies are focused on improving the current models to have similar dexterity as of the human hand. Many Robotic hands have been created to mimic the human hand functions and gestures but they still lack the dexterity, compactness or affordability for prosthetic use. In this paper we have reviewed recently designed rigid robotic hands having rotating finger joints and soft robotic tendon actuated hands that use a single elastic block to create the whole finger so to reduce the rotating finger joints after reviewing the designs we have compiled a set of points that can be used as the framework for a design that can overcome the limitations of the previous designs.
