Simple, but Ingenious.
Ugly, but Close.
虽然这款电机大脑人形机器人结构简单，却设计巧妙。
虽然他们外表有些丑陋，却兄弟情深。


A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm gear (which is similar in appearance to aspur gear).
蜗杆（螺旋齿轮）和涡轮（正齿轮）构成了蜗杆齿轮驱动系统。
Like other gear arrangements, a worm drive can reduce rotational speed or transmithigher torque.
同其他齿轮传动系统类似，蜗杆齿轮可以改变减速比和扭矩比。
One of the major advantages of worm gear drive units are that they can transfer motion in 90 degrees.
蜗杆齿轮的优点是可以实现运动的90度传递。
The gear ratio is: 1 to teeth of the worm wheel
减速比：1 / 涡轮的齿数
实际上蜗杆相当于齿数为1的齿轮。
The direction of transmission is not reversible due to the greater friction involved between the worm and worm-wheel.
仅可以蜗杆带动涡轮转动，不能实现涡轮带动蜗杆转动。
这是摩擦力在起作用。
Worm gear configurations in which the gear cannot drive the worm are called self-locking.
这种构造称作“自锁”。
