Robot based drive-through system for a super market

Abstract

This report describes the design and implementation of a robot based drive-through system for a super market. Drive-through is a type of service provided by businesses to allow their customers to purchase products without leaving their cars. The systems consists of three parts : an Android application that is used by the customers to remotely select the desired products, a Java program to process the orders, manage the products and customers database, control the robot, and monitor the state of the orders and the robot position on the map in real time. Finally a mobile robot controlled by an ESP32 Microcontroller used to collect the products in the supermarket. Orders are sent from the android application to the java program through internet, whereas the communication between the java program and the robot is done via wireless WIFI connection in a local area network. The results obtained were satisfactory for both the software and hardware parts, even though some constraints were faced on the hardware one.
