Conception and Fabrication of a Digital Shopping Trolley Based on Arduino

Abstract

In our everyday lives, doing food shopping and shopping at large retail malls is becoming an everyday activity in major centres. During the holidays and on weekends, shopping malls often have a lot of people there. When there is a discount being offered and when there is a festival going on, there is an even greater rush. People shop for a variety of goods and place them in the cart after making their purchases. After completing the purchase in its entirety, one must go to the billing area to make payments. In most cases, it takes up more time than the actual purchase process. Consequently, a shopping cart is an essential item when it comes to making purchases at shopping centres. On the other side, if the cart is too heavy, it will be difficult to transport the things that you have bought. As a result, to find a solution to the difficulty described above, we converted the standard trolley into an electronic trolley. Within these trolleys is a camera and barcode scanner that decodes the information that is accessible via the database about the items and then sends the decoded signal to the billing area. It is possible to avoid having to hurry when shopping thanks to the camera and barcode detection technology that is included inside the smart trolley. While the item is being placed in the trolley, an ultrasonic sensor will detect it and keep a count of it. Lastly, by using a Kinect sensor, it mimics human behaviour and functions as a follower. This human follower is using the phenomenon known as line following to track persons to make operating electric trolleys to move merchandise easier for senior citizens. Therefore, to make the tram even more intelligent, we added a Camera, a Barcode Reader, an Ultrasonic Sensor, and a Kinect Sensor.
