Voice-Controlled Robot Task Handoff Across Multiple Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where multiple robots are present, if a specific robot cannot perform a task corresponding to a user command, it may lead to user inconvenience.
Innovation Solution
A robot equipped with a microphone, camera, communication interface, memory, and processor that can acquire user voice, identify tasks, determine its capability to perform the task, and transfer the task to an external robot if necessary, using location and characteristic information to guide the user to the external robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robot determines it cannot perform a user's requested task, then service continuity is disrupted and user convenience deteriorates, but if the robot transfers task information to an external robot, then service continuity is maintained at the cost of increased system complexity
Solution Approach 1:
The patent introduces a communication interface as an intermediary mechanism that enables the robot to transfer task information to external robots. This mediator allows service continuity to be maintained without requiring direct complex integration between multiple robots, as the communication interface handles the coordination and information exchange centrally.
Solution Approach 2:
The robot system is designed with multi-functionality where any robot can potentially perform any task through collaboration. The robot can both perform tasks independently and transfer tasks to external robots, making the system universally capable of handling diverse user requests while maintaining service continuity.
2Measurement precision
If the robot collects and processes user characteristic information, then task transfer accuracy to external robots improves, but information processing time and computational load increase
Solution Approach 1:
The robot performs preliminary actions by collecting and processing user characteristic information (such as appearance features) before transferring the task to an external robot. This preliminary processing ensures that the external robot can quickly identify and serve the user without delay, as the characteristic information is already prepared and included in the task transfer packet.
3Measurement precision
If the robot moves to the target place before transferring the task, then user guidance accuracy improves, but energy consumption and operation time increase
Solution Approach 1:
The patent extracts the function of user guidance from the current robot's movement. Instead of the robot physically moving to guide the user, the robot transfers the task information including location details to an external robot that will be responsible for user guidance. This extraction reduces energy consumption while maintaining guidance accuracy through information transfer rather than physical relocation.

AI summary
A robot is provided. The robot includes a microphone, a camera, a communication interface including a circuit, a memory storing at least one instruction, and a processor, wherein the processor is configured to acquire a user voice through the microphone, identify a task corresponding to the user voice, determine whether the robot can perform the identified task, and control the communication interface to transmit information on the identified task to an external robot based on the determination result.
