So, as you can see in this prototype, gigantic piano strings, each string is controlled with a little robotic element -- either little bows that stroke the strings, propellers that tickle the strings, acoustic signals that vibrate the strings. We also have an army of robots on stage.
正如你在这里的样机上所看到的，长长的钢琴弦， 每根都被小型机器人部件所控制。 这里有小巧的琴弓来拨动，驱动器来撩拨， 声学信号来震动琴弦。在舞台上，还会出现一大群机器人。
