Replication of Human Hand Using Flex Sensor

This paper explores the robotic hand where the ability of a human to do a task is limited but not by his mental power but by his physical strength. In an environment where human interaction cannot be possible to do a particular job where the robots can do. Here we design a robotic hand where it is controlled by the interaction with the human hand using flex sensor, ARDUINO UNO, X-bee module (Wi-Fi module) & servo motor. The system works on the values sent by the flex sensor to the controller, the same is analyzed and calculated how much the hand and the fingers has to move to grab an object which is also controlled by the five servo motors by the controller. The signals are transmitted and received via the Wi-Fi module.
