Establishment of backup system for failed NC robot

Automotive assembly lines are often characterized by robots´ failures that may result in stoppages of the lines and manual backup of tasks. The phenomena tend to impair throughput rate and products´ quality. Hence, there is a need to develop low cost robot backup system with comparable efficiency. Here, an attempt is made to develop a electro-pneumatic system integrated with PLC as backup of NC Robot. The system developed can work at the time of emergency by replacing the NC robot. By this availability of backup it increases the production capacity, minimizes the line stop time and reduces down time.
