Robot Image Retrieval Using Shared Time-Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information providing systems that use robots to acquire and store visual and conversational data during travel fail to provide reproducible data if the robot is unable to acquire such data for any reason.
Innovation Solution
An information providing system that includes a robot with an imaging unit, a memory unit to store image data associated with position and time data, and a data extraction unit that can retrieve and display image data corresponding to user-instructed times and locations, even if the data was not acquired by the primary robot, by utilizing secondary robot data if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system stores only image data acquired by the user's own robot, then data storage is simple and manageable, but the system cannot provide reproducible data when the robot becomes incapable of acquiring visual data
Solution Approach 1:
The patent merges data from multiple robots into a unified storage system. The server stores image data acquired by not only the user's own robot but also by other robots in the network, creating a combined data pool that can be accessed by any user whose robot failed to capture the required data.
Solution Approach 2:
The server is designed with multi-functionality to serve multiple purposes: it acts as both a storage device for individual robots and as a shared repository for the entire robot network. This universal data storage and retrieval system allows any robot's data to be utilized by any user, enhancing system reliability without requiring complex individual robot capabilities.
2Reliability
If the system uses multiple robots to ensure data availability, then reproducible data can be provided even when one robot fails, but the system complexity and data management burden increase
Solution Approach 1:
The server acts as an intermediary between multiple robots and users. Instead of requiring direct peer-to-peer communication and complex coordination between robots, the server mediates data storage and retrieval operations, simplifying the overall system architecture while maintaining high reliability through multi-robot data collection.
3Loss of information
If the robot continuously acquires and stores all image data, then complete reproducible data is available, but storage space is consumed and data management becomes cumbersome
Solution Approach 1:
The patent combines storage resources across the robot network through the server. Instead of each robot needing to store all possible image data locally, the system merges storage capacities of multiple robots and the server to create a distributed storage network, reducing individual storage requirements while maintaining data completeness.

AI summary
An information providing system includes: a memory unit configured to store an image data acquired by an imaging unit a robot in association with a position data and a time data acquired by an information acquisition portion; a data extraction portion configured to extract an image data corresponding to a time and a position instructed by the user from among the stored image data; and a display unit configured to display an image based on the extracted image data. The memory unit stores the image data acquired by the imaging unit of a first robot moving with a first user and the image data acquired by the imaging unit of a second robot moving with a second user. The data extraction portion extracts an image data corresponding to a time and a position instructed by the first user from among the image data acquired by the second robot stored in the memory unit when the image data corresponding to the time and the position instructed by the first user is not present among the image data acquired by the first robot stored in the memory unit.
