AUTOMATED GUIDED VEHICLE WITH SENSORS FOR OBSTACLE AVOIDANCE

Abstract

The Prototype Design of Automatic Guided Vehicle (AGV) project aspires to construct a vehicle automatically guided with capability to follow the chosen path of travel and avoid collision with obstacle, if any in its path. In general, the environments where service robots perform tasks are shared with humans. In order to avoid disturbances due to robots, they can be designed to adhere to strict order like tracking on the predefined paths. This project main objective is to create an AGV that is completely autonomous, the vehicle is capable of receiving sensory inputs, interpreting those inputs to follow the predetermined path and avoid collision with any obstacles without any human intervention. The intelligence of the system is in the micro controller AT89C51. The micro controller takes inputs from the ultrasonic sensor to avoid collision by measuring the proximity of other vehicle or an obstacle and infrared sensors to sense its position relative to the path and steers accordingly to keep the vehicle on its predefined path. Micro controller drive AGV according to its program written in assembley language using two DC motors. Thus, the AGV is a good platform for robotics. On availability of good sensors, the AGV project can be extended to make a more sophisticated robot in the future.
