Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Guide robots often experience collisions with people due to unpredictable obstacle avoidance and lack of visible movement trends, leading to inefficient navigation and potential malfunctions.
Innovation Solution
A guide robot equipped with a signal receiving unit, controller, and light emitting module that calibrates its moving region by determining region calibration parameters based on movement instructions, using light displays to visibly indicate its movement path and trend, thereby preventing collisions and improving navigation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide robot uses sensor-based obstacle avoidance, then the robot can avoid obstacles automatically, but the avoidance direction is unpredictable causing multiple mutual avoiding events and extended navigation time
Solution Approach 1:
The patent applies preliminary action by projecting the robot's movement trajectory in advance using light emitting modules before the robot actually moves. This allows pedestrians to see the robot's intended path ahead of time and avoid the projected area, preventing multiple mutual avoiding events. The trajectory projection is performed before the robot executes the movement, giving pedestrians advance notice and enabling smoother navigation without repeated avoidance maneuvers.
Solution Approach 2:
The patent introduces an intermediary element - the light emitting module that projects visual trajectory information. This intermediary communicates the robot's intended movement path to pedestrians, serving as a mediator between the robot's navigation system and human pedestrians. Instead of direct sensor-based reactive avoidance, the light projection acts as an intermediate communication channel that enables coordinated movement and reduces conflict between robot navigation and pedestrian avoidance.
2Speed
If the guide robot moves suddenly from static state, then the robot can respond quickly to navigation instructions, but pedestrians cannot anticipate the movement leading to collisions
Solution Approach 1:
The patent applies preliminary action by projecting the robot's movement trajectory in advance using light emitting modules before the robot actually moves. This allows pedestrians to see the robot's intended path ahead of time and avoid the projected area, preventing multiple mutual avoiding events. The trajectory projection is performed before the robot executes the movement, giving pedestrians advance notice and enabling smoother navigation without repeated avoidance maneuvers.
Solution Approach 2:
The patent applies preliminary anti-action by using the light emitting module to project a visual warning of the robot's intended movement path before the robot actually moves. This preliminary visual indication serves as a preventive measure that counteracts the potential harmful effect of sudden movement by alerting pedestrians in advance. The light projection creates a virtual barrier that pedestrians can avoid, preventing collisions before they occur.
3Extent of automation
If the guide robot uses only sensor-based navigation, then the robot can operate autonomously, but the navigation path is not visible to pedestrians causing uncertainty and avoidance behavior
Solution Approach 1:
The patent applies color changes by using light emitting modules that can display different colors to represent different aspects of the robot's navigation. The trajectory projection uses visible light that pedestrians can easily perceive, making the robot's movement trend clear and distinguishable. Different lighting patterns or colors can indicate different navigation states, enhancing the information communication between the autonomous robot and pedestrians without compromising the robot's automated operation.
Solution Approach 2:
The patent introduces an intermediary element - the light emitting module that projects visual trajectory information. This intermediary communicates the robot's intended movement path to pedestrians, serving as a mediator between the robot's navigation system and human pedestrians. Instead of direct sensor-based reactive avoidance, the light projection acts as an intermediate communication channel that enables coordinated movement and reduces conflict between robot navigation and pedestrian avoidance.
