Robotic arms are designed for helping disabled people. The main function of the robotic arm is feeding food and drinks for disabled people. Nowadays there are so many robotic arms available in our market. These arms are more expensive because they use high-level technologies like sensing brain signals of arms and perform the task according to this. These expensive products are not affordable by common people. We are introducing this light weight portable robotic arm for feeding disabled people in affordable price. The ultimate aim of this proposed methodology is to assist the persons with movement disorder who need the help of someone to feed themselves. The proposed methodology comprises of four servo motors, one arduino controller and one usb camera. By detecting the eye blinking of the user, the operation will be initiated. The required height will be obtained by detecting the lip area of the user with the help of usb camera fixed on the robotic arm. Arduino uno is programmed in such a way to co-ordinate the required movements of the arm. The desirable robotic arm position is accomplished by the rotation of servo motors. The assistive feeding device has a gripper which can hold a spoon or a cup according to the written program. The motors will rotate in both directions to take the meals and drinks and feed to the user.
