图片不是你有时看见的概念产品的那种简单素描,不是“以防万一”的专利,看起来像很具体的真正设备的机械制图。当然,这并不意味着产品即将上市,更不用说最近会上市了。但是图片确实表明,DJI的工程师真的费时费力,让该产品成为现实。
Why have a “drone” on the ground when there are perfectly good ones for the air? Battery life, for one. Drones can only be airborne for a short time, even less when they’re carrying decent cameras and lenses. A ground-based drone could operate for far longer — though naturally from a rather lower vantage.
已经有超棒的空中无人机了,为什么还要陆上的“无人机”呢?一个原因是电池寿命。无人机只能在空中飞很短一段时间,装载像样的相机和镜头时,飞行时间就更少了。而陆上无人机的工作时间要长得多--不过自然,位置要更低。
Perhaps more importantly, however, a wheeled drone makes sense in places where an aerial one doesn’t. Do you really want to fly a drone through narrow hallways in security sweeps, or in your own home? And what about areas where you might encounter people? It would be better not to have to land and take off constantly for safety’s sake.
然而,也许更重要的是,有些地方适合用装轮子的无人机,而空中无人机则不行。你真的想让无人机飞过安检的狭窄过道,或者在家里飞吗?在那些可能遇见人的地方又怎样呢?安全起见,不让无人机频繁起飞降落会更好。
