Robot Navigation Using Cultural Conventions in Hallways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic systems fail to effectively navigate physical environments while adhering to cultural conventions, leading to potential collisions and inefficient movement, as they do not account for cultural norms and user preferences in their route planning.
Innovation Solution
The implementation of cultural convention data that specifies unidirectional regions and movement constraints, allowing the robot to determine routes that respect cultural norms and user preferences, using occupancy maps and constraint cost values to avoid obstacles and adhere to cultural conventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot uses traditional navigation methods without cultural convention data, then the route planning is simple and fast, but the robot may collide with users or move against cultural norms reducing user acceptance
Solution Approach 1:
The system performs preliminary action by pre-defining unidirectional regions and cultural convention rules before the robot executes navigation tasks. The occupancy map is preprocessed to identify regions where movement should be restricted to specific directions based on cultural conventions, allowing the robot to make quick decisions during operation without complex real-time calculations.
Solution Approach 2:
The system applies local quality by implementing cultural convention constraints selectively in specific regions rather than uniformly across the entire environment. Unidirectional regions are defined locally where cultural norms apply (e.g., hallways, corridors), while other areas maintain standard navigation freedom, thus balancing reliability improvement with minimal complexity increase.
2Ease of operation
If the robot adheres to cultural conventions by using unidirectional regions, then user predictability and acceptance improve, but the robot's movement flexibility and route options are reduced
Solution Approach 1:
The system implements dynamics by making the navigation constraints adaptive rather than static. The robot dynamically adjusts its route planning based on the current state, considering both cultural convention requirements and real-time environmental conditions. This allows the robot to maintain user predictability in cultural contexts while preserving flexibility when constraints are not applicable or can be temporarily relaxed.
Solution Approach 2:
The system segments the navigation space into regions with different constraint levels. By dividing the environment into unidirectional regions and free-movement regions, the robot can apply cultural conventions where appropriate while maintaining flexibility in other areas, thus resolving the contradiction between predictability and adaptability.
3Productivity
If the robot calculates aggregate cost values considering cultural conventions, then movement efficiency improves by avoiding obstacles and cultural violations, but the computational load and processing time increase
Solution Approach 1:
The system reduces computational load by performing preliminary calculations during map building and preprocessing. Cultural convention rules and unidirectional regions are identified and encoded in advance, so during actual navigation the robot only needs to query pre-computed data rather than performing complex optimization calculations in real-time, thus improving movement efficiency without significant time loss.

AI summary
A robot comprises a plurality of sensors on a mobile chassis and may move about an environment in which people may be expected to follow particular cultural conventions. Movement of the robot may be constrained to honor these cultural conventions that are appropriate for the people in the environment. For example, when the robot is used within the United States, the robot tends to move along the right-hand side of a hallway. In comparison, when the robot is used within Japan the robot tends to move along the left-hand side of the hallway. The cultural conventions may be implemented as one-way gates present at specified locations in an occupancy map of the environment. The gates have no physical presence in the environment, but have the effect of placing a constraint on where the robot is permitted to move.
