Robotic arm manipulator for industrial purpose

Abstract

Automation in industries helps in achieving the target of quality standardization and process visibility. In overseas the industries are automated using robotic arm which works efficiently. But in a developing country like ours, we can not afford to import those arms from overseas. Again our country is not technically sound enough to produce robotic arms commercially in large scale for industrial usage. Considering these aspects we have prepared a robotic arm manipulator which is efficient as well as cost effective. The robotic arm is able to pick and place objects controlled by three bipolar stepper motors. The motor will be operated in a closed loop (with feedback) system to reduce error. The operation of the stepper motor is controlled using RT - linux to minimize the real-time error (jitter). Two or more robotic arms can parrallely work by the algorithm. This made the project more efficient as from one computer we can operate all the manipulators. Stepper motors are used because it gives the steps so precisely. The motor is operated in closed loop to. The theoretical results are confirmed with practical application.
