AbstractThis paper proposes a Automated Robot for Warehouse using Image Processing. There are different types of Robot which can be divided into several categories this system deals with wheeled autonomous Robot. This Robot has no vision. Vision is maintained by PC or MATLAB with the help of web camera or any other digital camera. The AIM of this paper is to find shortest path and avoiding a obstacle for Robot based Image Processing technique in known environment (warehouse). The proposed system finds and analyses an optimal path for a Robot while avoiding obstacles along the way. The top view of warehouse is first captured as an image using web camera or any other digital camera. Shortest path is obtained by Template matching method and obstacle detecting methods are then performed to identify the existence of obstacles within the known environment.

General Terms

Robot-PC Interface ,Image Processing, MATLAB, Web camera.

control method for moving Robot in closed area is based on creation and sharing maps through shortest path finding and obstacle is proposed. Robot has sufficient intelligence to cover the maximum area of provided space. It will move in a particular direction and avod the obstacle which is coming in path. Autonomous intelligent Robots are Robot that can perform desired task in known environment without humans.

1. INTRODUCTION

   Nowadays Robotics is a part of advancement technology so this proposed system will make human life is easy. The use of vision in robotic application is rapidly increasing while the computer revolution that has taken place over the last 20 years has led to great advancement in the field of a digital Image Processing. Here the paper introduces a automatic Robot for Warehouse using Image Processing. Warehouse is large palce where different kind of goods loaded or unloaded. This system based on vehicle or device for avoiding accident and finding shortest path different methods by Image Processing using MATLAB software. The central processing unit consist of camera and a processor. The image is captured and information obtained from image processing exercise can be used to generate motion commands to be sent to the Robot. The Robot position is located in the image using the MATLAB. The destination to which the Robot has to reach is defined by the user. Depending on provided destination , the MATLAB code identifies the shortest path. Image Processing is form of signal processing where the input signal are images such as photographs or video processing. Video processing is nothing but sequence of images. Microcontroller is programmed to control dc motor upon receiving the data from the computer. The Robot transverse the path specified by the computer. The central processing unit captures an image every 500ms and provided an alternative path for the Robot to reach its destination if there are any dynamic obstacles in the path. Hence providing a feedback path

2. NECESSITY

   This system is design specially for find the obstacle and shortest path to reach the destination in the warehouse. As here using image processing for detection of obstacle, there is no use of sensors in circuit, hence circuit become less complex. As here also considering a shortest path to reach the destination the require time for operation will be less therefore speed of the operation will be higher. The accuracy of the system will be higher on the same hand we will require less man power and hence it will be more economical for the Industries & all the human errors will be automatically reduced.

3. SOFTWARE FLOW

   The shortest /optimal path is essential for the efficient operation of mobile robot. For any starting point within the environment representing the initial position of the mobile robot, the shortest path to the goal is traced by walking, avoiding obstacles, taking a correct decision, recognizing and the best reasoning. However, ambiguity of optimal paths exists where there exist two or more cells to choose the same least distance transform.

      Yes

   2. Work flow

      • Run time image acquisition

      • Extracting source, destination and obstacles.

      • Tracking shortest path from current location of robot.

      • Check for obstacle in path.

      • Corrective action in path.

      • Take place only when obstacle detected.

      • . Check for destination reached signal.

4. METHOD

   Image Acquisition: The web camera is automatically triggered by MATLAB commands and start taking snaps. Preprocessing of Image: In this images will resizes because there are multiple images will be processed having different size. After that color image converted into gray. Enhancement: It is necessary for improving appearance of an image. Its done by Histogram Equalization. Conversion: for measuring pixel length convert gray image into binary. Here using chain connectivity for find exact no of paths. Using different commands: like region props command to calculate image property like perimeter of length of pixel to determine shortest path. Template Matching method: Template Matching is technique in digital image processing for finding small parts of an image which match a template image. It can be used in manufacturing as part of quality control a way to navigate a robot or as a way to detect edges in images. Template Matching techniques are expected to address the following need provided a reference image of an object (template image) and an image to be inspected (the input image) so it want to identify all input image locations at which the object from the template image is present.

6. CIRCUIT DIAGRAM OF ROBOT

   A. Description of circuit diagram

   Reset is used for putting microcontroller at known condition. In order to continue its proper functioning it has to be reset, meaning all registers would be placed in a starting position. Pin OSC1 and OSC2 are provided for connecting a resonant network component. Pins OSC1 and OSC2 are provided for connecting a resonant network to form oscillator. The basic rule of placing crystal in board is that should be close to the microcontroller as possible to avoid interference in the clock. The design of power supply is depend on two step

   i.e. 1. Determine the total current sink from the supply. 2. Determine the voltage rating required for different components. RS32 IC is driver IC to convert microcontroller TTL (0-5v) logic to RS232 (o-9v) logic. DC driver circuit requires for giving direction to the DC motors.

7. CONCLUSION

In this way this paper proposes system which find shortest path from destination to source in known environment by using MATLAB software instead of using sensors or any other circuitry. This will be reduce human efforts. This will save time. This Robot is able to produce the basic walking movements using two gear motors. This concept had bridged the gap between the theory and practical about this subject. Using the benefits of modern IT-technology the distribution of information about the condition of the equipment can easily done by means of standardized web browser technology.
