Robot Obstacle Bypassing via Observation-Point Route Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-walking devices, such as sweeping robots, face challenges in efficiently navigating around continuous irregular obstacles or hidden obstacles behind wall corners, leading to collisions and prolonged cleaning times.
Innovation Solution
The method involves detecting an object to be circumvented and moving the self-walking device to an observation position away from the object, where it can gather information about the surroundings and plan a navigation route to avoid the obstacle effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the self-walking device adopts an along-the-wall obstacle avoidance strategy, then it can circumvent obstacles in front, but it easily collides with hidden obstacles behind wall corners and requires repeated recognition
Solution Approach 1:
The self-walking device performs preliminary actions by moving to an observation position before actually encountering hidden obstacles, gathering information about the environment in advance. This allows the device to plan its navigation route proactively rather than reactively, avoiding repeated collisions and recognition cycles
Solution Approach 2:
The observation position serves as an intermediary between the current position and the hidden obstacle. By moving to this intermediate position first, the device can gather information about hidden obstacles without directly approaching them, enabling better route planning before final navigation
2Reliability
If the self-walking device moves to an observation position to gather information, then it can plan navigation routes more effectively, but it requires additional movement and time
Solution Approach 1:
The device performs partial observation by moving to a specific observation position that provides sufficient information for route planning without requiring complete 360-degree surveillance. This partial action achieves the necessary navigation accuracy while minimizing additional time consumption

AI summary
A method and apparatus for bypassing an object, a medium and an electronic device. The method comprises: during a walking process of a self-walking device, when an object to be bypassed is detected, first moving to an observation location distant from said object, observing the situation around said object at the observation location, and planning a navigation route according to the situation. The method reduces the probability of collision of the self-walking device with a hidden obstacle, saves the time of repeatedly identifying the hidden obstacle, and improves the walking efficiency.
