Robotic Arm

Abstract

The technical development of industrial robots is one of the most dynamic development fields in electrical engineering. This project is about designing and manufacturing a cost effective, lightweight, user friendly and real time multi degree of freedom robotic arm to automate industries. The aim of this project was to develop a physical model of robotic arm for industrial applications. Basic hardware structure was designed using seven servos to allow multiple degrees of freedom. Servo motors connected directly to the programmable Arduino were used to drive the joints. Feedback from the pressure sensors were used by controller to help the arm in gripping objects. The robot was able to operate in both "LOCAL" and "REMOTE" modes. Local mode is required for specific repetitive tasks in industries e.g. pick and drop. It was implemented using hard-coding. Remote mode is required where movements of robot are task dependent and it was achieved by android Arduino interfacing. Bluetooth module was used to interface the app with Arduino. Designed app contains information about moving parts, pressure applied in gripping and option to move parts of the arm individually etc. The experiments were monitored and the results have been listed in this report.
