Solution Overview

Problem

Existing robot technologies struggle to execute tasks according to local conditions after relocation, leading to uncontrollable drift errors and failure to meet user requirements due to hijacking during autonomous navigation and localization.

Innovation Solution

A robot control method that determines its position and task execution area based on relocalization operations and environmental information, allowing the robot to adapt and execute tasks within the new environment without returning to the original hijacked position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the robot returns to the original hijacked position to continue executing the task, then the task can be completed, but the robot cannot adapt to local conditions and may not meet user requirements

Engineering Contradiction:

Improveadaptability to local conditionsVSAvoidtask execution reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The robot performs relocalization operation immediately upon detecting hijacking, determining its current position before deciding whether to return to the original position or execute tasks at the new position. This preliminary positioning action enables the robot to make informed decisions about task execution location, allowing adaptability to local conditions while maintaining task completion reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The robot dynamically adjusts its task execution strategy based on the hijacking situation. Instead of rigidly returning to the original position, the system evaluates whether to return or execute tasks at the new position, making the task execution process flexible and adaptive to different local conditions while ensuring task completion

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the robot performs relocalization operation to determine current position, then the robot can adapt to new environment, but uncontrollable drift errors occur in localization

Engineering Contradiction:

Improveability to adapt to new environmentVSAvoidlocalization precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The robot performs relocalization operation to obtain feedback on its current position after hijacking. This feedback mechanism allows the robot to determine whether it should return to the original position or execute tasks at the new position, enabling adaptation to the new environment while managing localization drift errors through continuous position verification

Inventive Principle:

Principle #23Feedback

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.
