Mobile Robot Destination Region Seeking and Client Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile robot systems face challenges in accurately designating destinations due to small user terminal screens, dynamic client locations, and discrepancies between the user commanding the robot and the intended service recipient, leading to difficulties in specifying precise destinations.
Innovation Solution
A mobile robot system that sets a region as a destination initially and then seeks and authenticates a specific client within that region after movement begins, using a user terminal to receive and transmit destination region information and employing autonomous movement and sensing units to navigate and identify the client.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a specific destination is designated using a user terminal, then the destination can be specified, but the small screen size makes it difficult to display detailed maps and accurately specify the destination
Solution Approach 1:
The destination specification process is divided into two stages: first specifying a destination region (coarse specification) and then specifying a detailed destination within that region (fine specification). This segmentation allows the system to overcome the limited screen area by breaking down the complex task into manageable steps that can be performed sequentially.
Solution Approach 2:
The system performs preliminary action by first designating a destination region before the robot starts moving. This preliminary region specification provides a broader context that can be displayed on the small screen, and then the client is sought and authenticated within that region after movement begins, effectively separating the regional selection from the precise location identification.
2Reliability
If the destination is set before movement, then the robot can navigate, but the client location may change making the destination inaccurate
Solution Approach 1:
The system performs preliminary action by first designating a destination region before the robot starts moving. This preliminary region specification provides a broader context that can be displayed on the small screen, and then the client is sought and authenticated within that region after movement begins, effectively separating the regional selection from the precise location identification.
Solution Approach 2:
The system transitions from a static destination specification approach to a dynamic one where the destination is initially set as a region and then refined based on real-time client detection. The seeking unit continuously searches for the client within the destination region during or after movement, allowing the system to adapt to changing client locations while maintaining navigation efficiency.
3Adaptability or versatility
If the user commanding the robot is different from the service recipient, then flexibility is improved, but identifying the correct destination becomes more difficult
Solution Approach 1:
The system introduces an intermediary authentication mechanism (such as face recognition or code verification) that bridges the gap between the commanding user and the service recipient. This intermediary step allows the robot to verify the actual client's identity within the destination region, ensuring accurate service delivery even when the commanding user and recipient are different persons.
Solution Approach 2:
The system implements feedback through client authentication processes that confirm the identity of the service recipient. The seeking unit detects potential clients and the authentication unit verifies their identity, providing feedback that ensures the robot delivers services to the correct person rather than just the location designated by the commanding user.

AI summary
A mobile robot includes a receiving unit that receives designation of a destination region including a destination, a moving unit that moves toward the destination region, and a seeking unit that seeks a client after movement toward the destination region starts. The moving unit moves toward the sought client.
