Perfecting a robot that bridges the gap will call for advances in almost every facet of modern robotics: artificial intelligence, machine vision, mechanical and electrical design, signal processing.

完善一台填补空白的机器人几乎要求现代机器人每一方面的先进技术：人工智能、机器视觉、机械和电气设计、信号处理。

Sound vibrations cause the stereocilia to bend slightly, causing mechanical vibrations that are then converted into an electrochemical signal that the brain interprets as sound.

声音振动使静纤毛轻微弯曲，造成机械振动，机械振动变成一种电化学信号，最后大脑将其理解为声音。

The receiver forwards the signal to an actuator, transforming the radio signal into the mechanical power by which the disk brake is activated.

信号接收器把无线电讯号转化成机械功率运送给驱动器实现制动。
