Automated Shopping Cart Using and An Indoor Positioning & Tagging System (IPTS) 

Project Overview

In this project, we will design a shopping cart that helps customers to find their desired destinations in supermarkets by using the UWB technology. In this paper, we will give the strategies to implement this project in details. The working vision is to have the customer select a destination within the supermarket using an LCD touch screen installed on the shopping cart handle. The indoor positioning system (IPS) well then determine the position of the cart and process path finding for it to reach the desired destination and guide the customer automatically. The customer follows the cart to the selected destination. The system will have subsystems to tag coordinates or supermarket sections, analyze & process data for path finding between the cart and sections, and implement control functionalities to move the cart towards any stationary section location while avoiding obstacles and maintaining the path. The project is simplified to not follow mapping procedures for multiple isles in the supermarket but only one for now to provide the working prototype before increasing the capabilities of the system in future stages. For now, we limit the guidance to 1 isle and not implement mapping features. The automated cart should arrive through lateral motion towards a location, moving until it could maintain 10-25cm tolerance. The following paper contains details on our first subsystem, the UWB radar. Also, it contains information with regards to our second subsystem, the robotic wheeled vehicle “Platform” that carries the tag unit which we desire to locate. Finally, we have the weight measurement subsystem to maintain constant speed regardless of the weight carried by the cart using load cells and sensor data acquisition and other electronics component for power and monitoring of battery capacity.


Project Objectives

  1. Reduce the time the customers spend looking for items in the supermarket – especially for offers and reduce the time staff spends guiding customers
  2. Prevent misdirection in supermarkets, smoother traffic
  3. Enable future development into commercial, residential, and many other applications by utilizing 5G and IoT and upkeeping with developing technologies.
  4. Demonstrate effectiveness of UWB Radar for use in indoor position system (IPS), an advanced-emerging market
