Project Overview • Assists shoppers • Navigation system with the ability to • Locate items • Provide detailed directions • Small scale proof of concept • Prototype cost: $230
Design Objectives • Locate items • Acquire user input • Query database for item information and location • Provide detailed directions • Obtain current cart location • Find optimal path from current location to the item
Software Components • OS: Ubuntu 10.10 Maverick Meerkat • Python programs • XBee control • Navigation algorithm • Positioning system • GUI • TKinter library
Software: Location Detection • Location determined by signal strength of beacons • Mapped to store layout Beacon Coverage Shelf
Software: Navigation • Proposed implementation: A* navigation algorithm • Finds least-cost path from a given initial node to destination node • Implemented Dijkstra’s navigation algorithm • More consistent performance and accuracy
Problems • Video output • S-Video • HDMI to VGA • Initial location detection • Touchscreen not recognized by Ubuntu • Scaling beacon network to store layout
Budget and Cost Analysis • Total Amount Spent: $230 • Total Estimated Parts Cost: $580 • Total Estimated Cost (Network with 5 nodes, including labor): $600 • Total Estimated Cost (1 unit, including labor): $450
