Solution Overview

Problem

Robots are limited to performing preconfigured tasks and struggle to adapt to user-defined tasks in complex environments, failing to efficiently locate and retrieve objects based on user instructions.

Innovation Solution

A method and apparatus that utilize a robot device equipped with image acquisition, machine learning models, and action models to determine a second physical space where an object is located, enabling it to access and retrieve the object even if it is not directly visible, by employing image recognition, language models, and action planning to navigate and interact with the environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If users manually search for and operate across multiple applications to complete tasks, then task completion is possible, but user time and operational complexity increase significantly

Engineering Contradiction:
Improvetask completion efficiencyVSAvoiduser time spent on task execution
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system automatically executes user tasks by self-managing the process of identifying required applications, switching between them, and performing operations without requiring manual user intervention for each step

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The virtual assistant provides a universal interface that can execute diverse tasks across multiple different applications through a single unified command structure, making the system adaptable to various app ecosystems

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the virtual assistant accesses detailed information from multiple applications, then task execution accuracy improves, but information security risks increase

Engineering Contradiction:
Improvetask execution accuracyVSAvoidinformation security exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system applies different access levels and permission strategies to different applications and data types, granting minimal necessary permissions for each specific task rather than universal access

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The virtual assistant acts as an intermediary layer between the user and application data, managing information access through controlled interfaces and permission protocols that prevent direct exposure of sensitive data

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the system integrates with multiple application ecosystems, then task versatility improves, but system complexity and development costs increase

Engineering Contradiction:
Improvecross-application task capabilityVSAvoidsystem integration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The virtual assistant implements a universal task execution framework that can interface with multiple application ecosystems through standardized protocols and common operation patterns

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system architecture divides the complexity into separate modules for each application ecosystem integration, allowing independent development and maintenance of each connector while sharing common core functionality

Inventive Principle:
Principle #1Segmentation

AI summary

A method, apparatus, device and medium for performing a user task are provided. In a method, a user task is received from a user, and the user task instructs a robot device to obtain a first object. A first image of a first physical space where a robot device is located is obtained. In response to determining that the first image indicates absence of the first object in the first physical space, a second physical space is determined. The robot device accesses a second physical space so as to obtain a first object. By means of the exemplary implementation of the present disclosure, the robot device can perform a user task in a complex physical space, so that the flexibility and accuracy of the robot device in performing a task in a complex environment can be improved, thereby completing an expected user task.
