The United States Navy has tested a new unmanned helicopter that can self-navigate to find a location using only an electronic tablet. The helicopter drone can avoid obstacles by itself, so all the pilot has to do is enter the coordinates of the destination.
The United States Navy has tested a new unmanned helicopter that can self-navigate to find a location using only an electronic tablet.
The helicopter drone can avoid obstacles by itself, so all the pilot has to do is enter the coordinates of the destination. Other drones need someone navigating them at all times, even if the pilot is doing so remotely.
Scientists have been developing the unmanned helicopter under a five year program, costing 100 million dollars.
Rear Admiral Matthew Klunder, who leads the US Navy's Office of Naval Research said: "With a touch of one button on my handheld, I can direct that helicopter to an unprepared landing site."
The technology can be used in the field to deliver supplies, or on rescue missions to remote areas.
Other new technology under development at the U.S. Navy is a rail gun that will be able to stop missile attacks using electromagnetic pulses fired from a cannon at eight times the speed of sound.
It can reportedly hit targets over a hundred nautical miles away.
This controversial weapon has been in development for ten years, costing the US government 240 million dollars, and some Congress members even tried to stop the development of the gun in 2011.
美国海军已经测试了一种新型无人驾驶直升机，可自行导航仅使用电子数位板找到一个位置。该直升机无人机可以避开障碍物本身，因此，所有的飞行员所要做的就是输入目的地的坐标。

该直升机无人机可以避开障碍物本身，因此，所有的飞行员所要做的就是输入目的地的坐标。 其他无人机需要有人随时浏览它们，即使飞行员这样做远程。
科学家们一直在发展无人直升机下一个五年计划，耗资1亿美元。
海军少将马修Klunder ，谁领导海军研究美国海军的办公室说： “随着触摸我的掌上电脑一个按钮，我可以直接说直升机毫无准备的着陆点。 ”
该技术可以在现场被用来运送物资，或救援任务到偏远地区。
正在开发的美国海军等新技术是轨道炮，将能够使用从大炮射向声音的八倍速度的电磁脉冲停止导弹袭击。
据说它可以击中目标百余海里之遥。
这个有争议的武器已经发展了十年，耗资美国政府2.4亿美元，而一些国会议员甚至试图阻止枪的发展在2011年。
