Rotatable Robot Face for Inter-Robot Conversation Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not enable error-free conversation between robots, as techniques for voice conversation between robots are still in the conceptual phase and not implemented in practice.
Innovation Solution
A robot system that includes a main body with a rotatable human face region, a signal generator, a communication unit, a speaker, and a controller, which generates and transmits data signals and voice signals through an external server to facilitate conversation between robots, ensuring accurate operation and direction of the robots' face regions towards each other for realistic communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voice conversation techniques between robots are implemented, then conversation capability is improved, but error-free communication is not achieved
Solution Approach 1:
The communication system is segmented into distinct functional components: a signal generator for creating data signals, a communication unit for transmission, a speaker for voice output, and a controller for coordination. This segmentation allows each component to be optimized independently, ensuring reliable data transmission while maintaining natural voice conversation capabilities between robots.
2Adaptability or versatility
If the robot main body is made rotatable with a human face region, then communication realism is improved, but device complexity increases
Solution Approach 1:
The robot's main body is designed with rotational capability, allowing the human face region to dynamically adjust its orientation toward the listener robot. This dynamic positioning enhances communication realism by enabling eye contact and proper visual alignment during conversations, while the rotational mechanism itself is implemented as a manageable component within the overall system.
3Reliability
If the speaker outputs voice signals after the main body rotation is controlled, then communication coordination is improved, but response time increases
Solution Approach 1:
The controller is designed to execute the rotation of the main body toward the listener robot before initiating the speaker output. This preliminary action ensures that the robot is properly oriented and ready for communication before delivering the voice signal, improving coordination. The timing sequence is optimized to minimize the total delay while maintaining proper communication etiquette and alignment.
Data Source
AI summary
A robot capable of conversation with another robot and a method of controlling the same are disclosed. The robot includes a main body having a first region corresponding to a human face and rotatable in left-right direction directions, a signal generator generating a first data signal to be transmitted to a listener robot and a first robot voice signal corresponding to the first data signal, a communication unit transmitting the first data signal to an external server, a speaker outputting the first robot voice signal, and a controller controlling a rotation direction of the main body such that the first region is directed toward the listener robot at a time point adjacent to a transmission time of the first data signal and controlling the speaker to output the first robot voice signal after the rotation direction of the robot is controlled, wherein the listener robot receives the first data signal transmitted from the external server and is controlled to operate based on the first data signal.
