| Summary: | 碩士 === 國立雲林科技大學 === 資訊工程系 === 105 === This paper discuss about the synchronization of multi-robot control via humandroid. Different to detecting beat of music, the robot control code-“Action Code” encoded as Acoustic Signal and mix with Dancing music. After playing this music via speaker, robot can decode Action Code from Music via Microphone and dance corresponding Action Code Synchronously.
We use DFT (Discrete Fourier Transform) to transfer signal between time domain and frequency domain. We choose three acoustic frequency to design four Symbols to transmit data. The transmitter transfer Action Code from frequency domain to time domain and transmits it via speaker. The Receiver receive Music via Microphone and decode Action code by transferring time domain data back to frequency domain. Thus the robot now can dance by Action code. We use two symbols- SGain and SGuard to lower the influence of frequency response due to different Microphone. To Lower the error rate of transmission, we use Shortest Hamming Distance mechanism to design Action Code. On choreographer of robot dance, we consider about exclusion relationship between some dance sets and time duration, thus the robot can dance smoothly. The result shows that our System have good result on multi-robot dance.
