They're powered by brushless motors and some onboard machine learning.

它们由无刷电和一些学习驱动。

Designed by Shift Robotics, an offshoot of Carnegie Mellon University, Moonwalkers consist of a 300W brushless motor in each 4.2-lb (1.9-kg) shoe that powers eight polyurethane wheels.

“月球漫步者”由美国卡耐基梅隆大学下属Shift Robotics公司设计，每双重量为1。9千克鞋中包含一个300瓦无刷电，为8个聚子提供动力。

So we have a relative small volume and we needed to fit a brushless motor controller, a flywheel, a breaking mechanism, electronics a radio and a battery.

所以我们体积相对较小，我们需要安装无刷电控制、飞、制动构、电子设备、收音和电池。
