Dual-Sided Guide Robot Display Access During Concurrent Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Guidance robots with displays on both surfaces face usability issues due to simultaneous usage causing confusion, restricted access, and safety concerns when one display is in use, leading to diminished effectiveness.
Innovation Solution
A guidance robot with dual touchscreens on the front and rear surfaces that allows restricted use of the rear touchscreen based on the state of the front touchscreen, notifying users of restrictions and adjusting screen content accordingly to enhance usability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robot guides patients through long corridors and elevators, then the robot's autonomy and navigation capability should be high, but the robot may get lost or fail to guide accurately
Solution Approach 1:
The patent introduces a server as an intermediary between the guide robot and the hospital map database. The server receives location information from the robot, determines the next destination by comparing current location with destination, and provides guidance instructions. This intermediary approach resolves the contradiction by externalizing the complex navigation logic to a dedicated server, allowing the robot to maintain simple onboard systems while achieving high guiding accuracy through server-assisted navigation.
2Extent of automation
If the robot operates autonomously without manual intervention, then automation level should be high, but the robot cannot handle unexpected situations or complex decisions
Solution Approach 1:
The patent implements a feedback mechanism where the robot continuously sends location information to the server, receives guidance instructions, and executes them. The server continuously monitors the robot's progress by comparing current location with destination, and adjusts guidance instructions accordingly. This closed-loop feedback system enables high automation while maintaining adaptability, as the server can dynamically respond to unexpected situations by recalculating routes or providing alternative instructions based on real-time robot status and environmental conditions.
3Ease of operation
If the robot follows pre-set routes, then navigation simplicity should be high, but the robot cannot adapt to closed construction sites or changed environments
Solution Approach 1:
The patent implements dynamic navigation where the route is not fixed but continuously adjusted based on real-time conditions. The server receives location information from the robot, determines whether the current location matches the destination, and dynamically generates or modifies guidance instructions. This allows the robot to follow simple pre-set routes under normal conditions while automatically adapting to environmental changes such as construction sites or closed areas, as the server can recalculate and provide alternative routes dynamically.

AI summary
A guide robot (100) and an operation method of same are disclosed. A guide robot (100) according to the present disclosure may, when there is a request for use of a rear side display (151b) while a front side display (151a) is in use, allow a limited use of the rear side display (151b) and provide a screen corresponding to the request for use. In this case, a range of the limited use may be determined differently according to a use state of the front side display (151a).. Accordingly, a double-sided display is utilized more efficiently, and thus the usability of a guide robot is extended.
