Solution Overview

Problem

Existing robot control methods fail to adapt tasks according to local conditions after relocalization, leading to inefficiencies and inability to meet user requirements.

Innovation Solution

A robot control method that determines its position and task execution area based on environmental information after relocalization, allowing flexible task execution without returning to the original hijacked position, thereby adapting to local conditions and meeting user requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the robot returns to the original hijacked position after relocalization, then the localization accuracy is improved, but the task execution flexibility and adaptability to local conditions deteriorate

Engineering Contradiction:
Improvelocalization accuracyVSAvoidtask execution flexibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the robot's post-relocalization behavior adaptive rather than fixed. The control method dynamically determines whether to return to the original position or execute tasks at the current position based on real-time environmental information and task requirements, allowing the system to flexibly adjust its behavior pattern

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the decision parameter from a fixed rule (always return to original position) to a variable decision based on environmental conditions. By introducing environmental information assessment and task requirement matching, the system transforms the binary choice into a conditional decision-making process that optimizes between localization accuracy and task execution effectiveness

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the robot executes tasks at the current position after relocalization, then the task execution flexibility is improved, but the localization accuracy deteriorates

Engineering Contradiction:
Improvetask execution flexibilityVSAvoidlocalization accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent transforms the fixed localization accuracy parameter into a conditional parameter that varies based on environmental assessment. By introducing environmental information as a decision variable, the system allows localization accuracy to be optimized when returning to original position while permitting task execution at current position when environmental conditions support it

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system dynamically adjusts the balance between localization accuracy and task execution flexibility by continuously assessing environmental information. The control method enables real-time switching between prioritizing localization precision and prioritizing task execution adaptability based on current conditions

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the robot always returns to the original hijacked position after being hijacked, then the system simplicity is maintained, but the user requirement satisfaction and task efficiency deteriorate

Engineering Contradiction:
Improvesystem simplicityVSAvoidtask efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent changes the control parameter from a simple fixed rule to a conditional decision-making parameter that incorporates environmental assessment. This transforms the control logic from unconditional return behavior to conditional behavior that optimizes task efficiency while maintaining reasonable system complexity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies preliminary action by assessing environmental information before deciding the robot's next action. By performing environmental evaluation in advance, the system can make informed decisions about whether to return to the original position or execute tasks at the current position, improving task efficiency without significantly increasing system complexity

Inventive Principle:
Principle #10Preliminary action

AI summary

The embodiment of the present disclosure provides a robot control method, a robot and a storage medium. In the embodiment of the present disclosure, the robot determines a position when the robot is released from being hijacked based on relocalization operation; determines a task execution area according to environmental information around the position when the robot is released from being hijacked; and afterwards executes a task within the task execution area. Thus, the robot may flexibly determine the task execution area according to the environment in which the robot is released from being hijacked, without returning to the position when the robot is hijacked, to continue to execute the task, then acting according to local conditions is realized and the user requirements may be met as much as possible.
