Design and Implementation of Voice Controlled Robotic ARM

Abstract

Modern technologies have required the labor market to provide robots that work in many fields, including industrial, medical, military, and agricultural [3]. In this project we design a robotic arm that enters in many areas that can be used in oil fields that are dangerous to operators working on sites containing inert gases or in environmentally polluted areas. The aim of the design is to make the robot arm fully operate by voice, that is, it responds to commands issued by the operator. There are many methods that can be used to make the robot work without controlling it manually, but each design has a special practical character, as the sound-based approach makes the robot practically easier and efficient to perform accurate tasks in dangerous places. A robotic arm is classified from a group of units: (arm, Arduino controller, NRF sensor, and voice module). The arm contains the main base, three rotary joints and an end-effector, in which the rotational motion is provided by a servo motor. The NRF sensor has been placed to be a wireless remote control for a distance up to one kilometer and can work inside and outside buildings. The arm is programmed by training the voice sensor on the voice commands (hello, right-left, up down, forward - reverse, catch - open).
