Robotic arm showing writing skills by speech recognition

Robotic arms are programmed robot manipulator with similar functions of a human arm. Several kind of high technology prostheses are available for doing the basic functions of human arm. Aim of our project is to develop a robotic arm which helps the physically handicapped person to write. The robotic arm is to be fitted to the patient´s amputee hand, and will write down the words that the patient pronounces to the microphone. The special feature of this robotic arm is that it is fitted with a pen which performs the writing operations. This paper describes the design of the robotic arm, advantages and drawbacks of this arm.
