Abstract
The designed robotic hand is a prototype robot for household purpose which aims to act as an aide for humans especially those who have lost their one hand. It can perform various tasks without the need of human help. These tasks include lifting and moving objects. The robotic hand is controlled by five servo motors i.e. one for each finger. These servo motors can be moved at any angle as per requirement. These servo motors are interfaced with Main Control Unit (MCU). Its MCU is based upon Arduino. The robot has been wirelessly controlled with the help of Bluetooth Transceivers HC-05., which can provide user the control of robot up to range of 100m. We used two methods to control the movement of robotic hand i.e. through flex sensor and by extracting the muscle signals of hand. The robotic hand can also be used for multiple tasks such as bomb diffusion, aid for needy people, surgical purposes etc.
