A mechanical arm is robotic, usually programmable, with similar functions to a human arm. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be considered to form a kinematic chain. The business end of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand. The end effector can be designed to perform any desired task such as welding, gripping, spinning etc., depending on the application. My idea is to make a robotic arm which works on slightly movement of muscles for disabled persons to fulfill the duty to assist in the daily activities likes playing chess with friends
or drinking water.In this project i have used motors that is operated by sensors which will work on the movement muscles of hand.The only goal of the project is to integrate into society and improve the quality of life of persons with disabilities.
