韩国团队研发出可跨越障碍的车轮
📖 逐句对照翻译
Imagine a wheelchair equipped with wheels flexible enough to move over all kinds of barriers: including the raised edges of streets.
想象一下，一辆配备足够灵活车轮的轮椅，能够越过各种障碍物：包括街道凸起的边缘。
A robotic delivery vehicle could use the same wheels to go up stairs to deliver food or other purchases.
机器人送货车辆可以用同样的轮子爬楼梯，递送食品或其他购物物品。
This is what researchers from the Korea Institute of Machinery and Materials (KIMM) see as the future for their 'morphing' wheel.
这就是韩国机械与材料研究院（KIMM）的研究人员所设想的“变形”车轮的未来。
The wheels can change their shape and can roll over barriers up to 1.3 times their radius.
这种轮子可以改变形状，能够越过高达其半径1.3倍的障碍物。
The radius of a wheel is half its height.
车轮的半径是其高度的一半。
Other possible applications for the morphing wheel include robots that gather information about an enemy in the battlefield.
变形轮的其他可能应用包括在战场上收集敌方情报的机器人。
The KIMM team also hopes that morphing wheels will one day be used with two and four-legged robots.
KIMM团队还希望，变形轮有一天能用于两足和四足机器人。
Now, the movement of those machines is limited.
现在，这些机器的移动范围是有限的。
Too much shaking is also a problem.
摇晃得太厉害也是个问题。
With the morphing wheels, the robots could carry objects that need smooth movement for industrial use.
借助变形轮，机器人可以搬运那些在工业应用中需要平稳移动的物体。
Aim to increase speed
旨在提高速度
Song Sung-hyuk is the lead researcher at South Korea's KIMM and a member of the AI robotics research team.
宋成赫是韩国机械材料研究院（KIMM）的首席研究员，也是人工智能机器人研究团队的成员。
He said the goal is to make the wheels work at the average speed of a car.
他说，目标是让车轮以汽车的平均速度运转。
That is about 100 kilometers per hour.
那大约是每小时100公里。
Wheels developed for a similar purpose, such as airless wheels, have flexibility but are limited in their ability to overcome barriers, said Song.
宋表示，为类似目的开发的轮子，例如无气轮胎，具有灵活性，但在克服障碍方面的能力有限。
The difference between airless wheels and the morphing wheel is that airless wheels are always soft, but the morphing wheels can change from hard to soft when they meet a barrier.
无气轮胎与变形轮胎的区别在于，无气轮胎始终保持柔软，而变形轮胎在遇到障碍物时可以从硬变软。
They can then return to being hard to permit faster travel where there are no barriers.
然后，它们可以恢复为难以获得许可的状态，以便在没有障碍物的地方实现更快的通行。
The morphing wheel is made of an outer circle of chain and a series of wires running through its central hub.
变形轮由一个链条构成的外圈和一系列穿过其中心轮毂的金属丝组成。
A sensor controls the stiffness of the wires in reaction to the barriers in its path.
传感器会根据路径上的障碍物来控制导线的刚度。
Song's team demonstrated to Reuters a model of a wheelchair riding on morphing wheels as it climbed stairs with 18-cm steps.
宋的团队向路透社展示了一款轮椅模型，它借助变形轮子攀爬18厘米高的台阶。
The team has also tested a device using the wheel at speeds of up to 30 kilometers an hour.
该团队还在最高每小时30公里的速度下测试了一款使用该车轮的装置。
I’m Andrew Smith.
我是安德鲁·史密斯。
