INTRODUCTION Now a day’s industries are highly automated for various applications. Automated guided vehicles are now widely used in many industries due to the high level of performance and reliability. All guided vehicles feature some kind of obstacle avoidance. The functions of guided vehicles is to carrier a material and deliver products from one manufacturing point to another; where rail, conveyer and gantry systems are not a suitable option. Designing autonomous vehicle requires the integration of many sensors and actuators according to their task. Obstacle detection is primary requirement for any autonomous vehicle. The vehicle acquires the information from the outside environment and process it according to the sensor mounted over it. Various types of sensors are use for the obstacle detection which is ultrasonic sensors, laser sensor, bump sensors, infrared sensors and soon can be used. Among these entire sensor infra red sensor is most suitable because of its low cost and ranging capability. The guidance systems consist of infra red sensor for obstacle detection, range determination and avoidance the unit is highly resistant to ambient light and nearly impervious to variations in the surface reflectivity of the detected object. It can detect the obstacle within the range of 10 to 80 cm. These systems consist of infra red sensor and micro-controller the sensor is mounted on the vehicle to acquire the information from its surrounding. The infra red sensor is most suitable because of its low cost and ranging capability. The performance measurements indicated by the zigbee software using visual basic which provide the wireless communication for the long distance. Background theories and techniques of Electronic control Technology and analyzed in this paper using both hardware and software consideration. II. SYSTEM DESCRIPTION This vehicle is designed to detect the obstacle and avoiding collision base on the distance measurement information obtained from the infra red sensors. Hardware circuit of Automated Transportation mechanism and Obstacle Detection consist of two parts transmission of data though transmitter circuit which consist of zigbee transmitter and a receiver circuit which called as zigbee receiver which receives the data entry though the programmer. Receiver circuit also consists of an IR Sensor which is connected to the microcontroller for obstacle detection.The transmitter circuit is consist of an zigbee transmitter and power regulator LM317 for 3.3V and db 9 connector though pin no. 13 & 14 of the IC in which 5V supply is provides to data is enter though the programmer. Circuit diagram of transmitter is shown in fig 1. Here the data is received by the zigbee receiver which is controlled though the microcontroller IC AT89S52 which control the movements of the motors and up-down movements of the rack and pinion though the relay IC ULN 2003 which is connected to the six motor and the six coil the ULN2003 send the signal according to which the motor movement are decided. Here, an obstacle detection IR (Infrared sensor) sensor is also used for the detection of obstacle during the ABSTRACT: The automotive sector is widely recognized as one of the industries with greatest importance and can assume in the development of a country economy this master's thesis is about the implementation and evaluation of Automated Transportation mechanism and Obstacle Detection. By using a real time visual basic concept. A concept of automated transportation by a cooperative which enable robots to process a complicated or heavy duties task and over the large abstraction in the environment a method transportation utilizing forklift mechanism for lifting process and moving process. The path is store in memory by the programmer, the motion of the vehicle is controlled by stepper motor and controlling of the machine is done by micro- controller. Autonomous robotic vehicle guidance has been developed for industrial difficult. KEYWORDS: Automated guided vehicles; IR sensors; zigbee transmitter; zigbee receiver microcontroller.
