Indoor Drone Inventory Scanning for 3D Warehouse Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current warehouse inventory management systems face challenges such as human error in scanning and tracking items, difficulties in locating specific items, issues with duplicates or lost items, and safety hazards from traditional tools and machines, leading to costly under- or overstocking problems.
Innovation Solution
The implementation of aerial drones equipped with optical sensors and indoor positioning systems for navigation and identifier detection, which communicate with a warehouse management system to accurately scan and track inventory items, addressing the limitations of two-dimensional robotic systems by enabling three-dimensional scanning and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handheld label scanners are used for inventory tracking, then inventory management can be performed, but human error in scanning and updating inventory information occurs
Solution Approach 1:
The drone system performs inventory scanning autonomously without human intervention. The drone navigates warehouse aisles automatically, scans barcodes using onboard cameras, and uploads data to the inventory management system, eliminating manual scanning operations and associated human errors
Solution Approach 2:
The patent replaces manual mechanical scanning operations with an automated aerial drone system equipped with optical sensors and barcode scanning capabilities, substituting human labor with autonomous robotic technology
2Extent of automation
If ground robots are used for inventory management, then automated tasks can be performed, but they can only move in two dimensions and cannot see individual cases and packages at different heights
Solution Approach 1:
The patent transitions from two-dimensional ground-based robotic scanning to three-dimensional aerial drone scanning. The drone's ability to fly at varying heights and angles provides comprehensive visibility of inventory items stacked on shelves, capturing barcodes on cases and packages at different vertical positions that ground robots cannot access
3Productivity
If traditional tools and machines are used for inventory checking, then inventory management can be performed, but safety hazards to human workers occur
Solution Approach 1:
The drone system performs all inventory scanning and data collection tasks autonomously without human workers being present in the warehouse aisles, completely eliminating exposure to safety hazards from forklifts, pallet movers, and other heavy equipment
Solution Approach 2:
The patent introduces an autonomous drone as an intermediary between inventory management needs and physical inventory items, allowing data collection to occur without direct human involvement in potentially hazardous warehouse environments
Data Source
AI summary
A system that employs aerial drones for inventory management is disclosed. The system includes at least one aerial drone with an optical sensor, an indoor positioning system, and a controller on the aerial drone. The controller is communicatively coupled to the optical sensor and the indoor positioning system. The controller is configured to localize and navigate the aerial drone within a facility based on one or more signals from the indoor positioning system. The controller is further configured to detect identifiers attached to respective inventory items via the optical sensor and to store information associated with the detected identifiers in an onboard memory. The controller may be further configured to transmit the information associated with the detected identifiers to a warehouse management system.
