Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If robot swarms rely on electromagnetic communication, then communication speed and data transmission are improved, but vulnerability to electromagnetic disruptions increases
Solution Approach 1:
The system changes the communication parameter from electromagnetic signals to acoustic signals when disruptions are detected. This parameter transformation allows the robot swarm to maintain communication functionality by switching to a different physical domain (acoustic waves) that is not susceptible to electromagnetic interference, thereby resolving the contradiction between speed and reliability.
Solution Approach 2:
Acoustic signals serve as an intermediary communication medium when electromagnetic communication fails. The system introduces this alternative mediator to transfer information between robots, ensuring continuous operation even when the primary electromagnetic communication channel is disrupted.
2Reliability
If robot swarms switch to acoustic communication, then resistance to electromagnetic disruptions is improved, but communication bandwidth and speed may be reduced
Solution Approach 1:
The communication system is designed to be dynamic, automatically switching between electromagnetic and acoustic modes based on environmental conditions. This dynamic adaptability allows the system to optimize for reliability when electromagnetic disruptions occur while maintaining the option to use higher-bandwidth electromagnetic communication when conditions permit.
Solution Approach 2:
The system employs periodic communication attempts across different modalities. When acoustic communication is activated, it uses structured periodic signal transmission to maximize information transfer efficiency within the constraints of the acoustic channel, mitigating the bandwidth limitation.
3Adaptability or versatility
If robot swarms equip multiple microphones and speakers, then acoustic communication capability is improved, but device complexity increases
Solution Approach 1:
The microphones and speakers are designed to serve multiple functions: primary electromagnetic communication, backup acoustic communication, and environmental sound detection. This multi-functionality justifies the added complexity by providing a single set of components that fulfill multiple communication and sensing roles within the robot swarm.

Implementation Method 1
exchanging an acoustic signal between one of the speaker and at least one of the microphones of the given robot and one of a corresponding microphone and a corresponding speaker of a corresponding communication partner
Implementation Method 2
The acoustic signal may have a frequency range outside the upper frequency of the audible range of one or more of humans and animals. The frequency range of the acoustic signal may be over about 15 kHz.

AI summary
There are provided robot swarms and methods of operating thereof. Such a swarm may include two or more robots each having a microphone, a speaker, and a communication terminal for sending or receiving an electromagnetic signal to or from a communication partner to affect electromagnetic communication with the communication partner. Upon detection of a disruption to the electromagnetic communication, a given robot of the two or more robots may switch from electromagnetic communication to acoustic communication by exchanging an acoustic signal between one of the speaker and the microphone of the given robot and one of a corresponding microphone and a corresponding speaker of a corresponding communication partner.
