Robot have become common place in industrial environment mainly in the automobile industries, allowing task from the most repetitive to the most complex and hazardous to be automated. The purpose of this work is to study the behavior of the automated arc welding system using 6-axis vertically articulated arc welding robotic arm and Programmable Logic Controller. The actuators, controllers and driver hardware systems have been introduced. The system has been designed keeping in mind the size of the jigs/fixtures, robotic arm and accordingly the selection of the controller and servo motor to...

During the past three decades, there have been considerable advances in the prevention, diagnosis and treatment of craniomaxillofacial (CMF) injuries. Preventive legislation (speed limits, alcohol restriction, use of helmets, shoulder and seat restraints), improved road construction measures and vehicle safety modifications (safety glass, padded dash boards, stronger frames, collapsible steering columns, airbags) have led to a significant decrease in the incidence and severity of road traffic accidents (RTA) in some countries. Trauma is the leading cause of morbidity and mortality/death in...
