Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If robot navigation relies on static global maps and traditional path planning, then the navigation system has a clear framework for path determination, but it cannot adapt to dynamically changing environments leading to navigation inaccuracies
Solution Approach 1:
The patent applies dynamics by transitioning from static global map-based navigation to dynamic indication information-based navigation. The robot continuously detects real-time indication information (visual markers, wireless signals) during travel and adjusts its path accordingly, making the navigation system adaptive to environmental changes while maintaining accurate path determination through real-time signal tracking
Solution Approach 2:
The patent implements feedback mechanisms by continuously detecting indication information during robot travel and using this real-time data to adjust the travel path. The system monitors the robot's position relative to the destination through ongoing detection of indication information and dynamically recalculates the optimal path, creating a closed-loop control system that improves both adaptability and accuracy
2Reliability
If robot navigation uses environmental perception and obstacle avoidance, then the robot can respond to real-time environmental changes, but the navigation becomes difficult to accommodate dynamically changing environments
Solution Approach 1:
The patent introduces indication information (visual markers, wireless signals) as an intermediary between the robot and the environment. These intermediaries provide structured, detectable references that guide the robot through dynamic environments, allowing reliable environmental response while maintaining adaptability through the flexible interpretation and tracking of these intermediary signals
3Device complexity
If robot navigation relies on static global maps, then the path planning has a predetermined framework, but the navigation signals may be limited and the maps may not reflect real-time environmental changes
Solution Approach 1:
The patent applies preliminary action by pre-deploying indication information (visual markers, wireless signal sources) in the target area before robot navigation begins. These pre-placed intermediaries provide continuous real-time positional guidance throughout the robot's travel, ensuring accurate navigation without requiring complex real-time environmental mapping while preventing information loss through persistent signal availability

AI summary
Embodiments of the invention relate to a method, apparatus, device and a storage medium for robot travel. The provided method includes: determining a destination of a target robot in a target area; in a process of the target robot traveling toward the destination, detecting, in an environment in which the target robot is located, indication information for the destination; and in response to detecting the indication information, determining, based on a current location of the target robot and the indication information, a target travel path of the target robot from the current location toward the destination. In this way, the target robot can be helped to adjust in the traveling process based on the indication information, thereby ensuring that the target robot can accurately and stably reach the end point.
