Robotic Arm Motor Angular Application

Abstract

This is a survey paper on a robotic arm and their development. It gives a technical introduction to some of the recent research work in this field. This is a working field of research in which there are a number of outstanding open problems and an area of exploration. Nowadays, a different variety of robotic arms are commercially available. Some of them are excellent in accuracy and repeatability. In this paper, we understand the evolution of robotic arm in last 20 years and described different parameters of an arm. Type of robotic arm only depends on these parameters. Our survey may be used for knowledge and guidelines for future research work. The paper concludes with research gaps and proposed work. Robotic arm uses in the different fields like a household, workplace, and working station. Keywords-Robotic arm, axis, degree of freedom, working envelope and space, kinematics, payload, speed and acceleration, accuracy and repeatability.The project is a Robotic Arm that can identify different objects located in its workspace according to their shape and color and places the objects in a certain location with the help of a video camera as a visual feedback. The arm has 4 Degrees of Freedom (DOF) with a DC-Motor at each joint. The DC-Motor is position-controlled using a PID controller to position the link at the required angle; the feedback of the angle is measured using rotaryencoders. This project introduces intelligence to industries to reduce human errors and increase the quality and mass production of industries. It can operate under hazardous circumstances (high pressure, high temperature and locations that can be unstable for human operation) so it reduces that risk for human injures. It can be updated and controlled easily to achieve a larger number of applications. It has a simple graphic user interface (GUI) that can easily be used by any worker or operator not precisely an engineer. It reduces the costs as it can perform a task that is done by many workers using only one operator. Goal of the work: the goal of this project is to control the angles of a robotic arm joints using a PID controller with a DAQ card and a computer system as a digital controller.
