LINE TRACING TROLLEY USING ARDUINO WITH AUTOMATIC BILLING SYSTEM

Electronics and Instrumentation Engineering

Microcontroller based design, has acquired the status of most happening field in electronics. This is highly specialized field that has the power of integrating thousands of transistors on single silicon chip. In a mall every time customer has to pull the trolley from rack to rack for collecting item and at the same time customer has to do calculating the price. To avoid this procedure like pulling trolley, waiting queue, calculating price etc by comparing different existing method we proposing new method. According to that the customer can select the trolley and select the purchasing item from the computer monitor using android based application and transmit data to the trolley. The main algorithm of the software depends up on the position of the items. The arduino uno based trolley is line following and, it is having a distance sensor. According to the instruction the trolley is moving, after covering the corresponding distance the trolley will stop ,the items from rack is pick and place to the trolley using robotic arm. After collecting all items the trolley will move to the billing counter. Trolley movement is controlled by motor drive circuit. By using this trolley customer can buy large number of product with less time with less effort. At the billing counter computer can be easily interfaced for verification and bill print out.
