WEBVTT 00:00:02.740 --> 00:00:05.840 I have a DJI phantom I have the first generation version 00:00:06.046 --> 00:00:09.866 That's the one you can mount to Go Pro 2 and you can take HD videos 00:00:09.945 --> 00:00:13.795 it's got about 15 minutes flight time and fly around and have a good time with it 00:00:19.936 --> 00:00:22.376 These days drone seem to be every where 00:00:23.268 --> 00:00:24.928 They might seem fun at first 00:00:24.989 --> 00:00:28.989 But when you hear stories about drones crashing into the side of buidlings 00:00:29.535 --> 00:00:31.555 You might be wondering, are they safe? 00:00:31.704 --> 00:00:35.704 I mean I think it really depends on the operator and someone's experience 00:00:37.284 --> 00:00:42.224 As an avid UAV builder, Kon customized his quadcopter and link it to a computer on wheels 00:00:22.737 --> 00:00:22.987 When you come around the side of the building you know that someone is walking on the street 00:00:22.987 --> 00:00:35.170 The wind direction can change very suddenly 00:00:51.631 --> 00:00:53.371 and it can be a big gust and the altitude is even more so 00:00:54.751 --> 00:00:58.751 I think that at a good balance it can be strup between safe view and being able to keep the hobby alive................. 99:59:59.999 --> 99:59:59.999 Most drones do have CTV feature build-in, 99:59:59.999 --> 99:59:59.999 If an RC or GPS signal is lost causing the drone to go MIA 99:59:59.999 --> 99:59:59.999 or if the battery gets low 99:59:59.999 --> 99:59:59.999 the field safe mode kicks in and sends the drone home autonomously 99:59:59.999 --> 99:59:59.999 Buried inside, electrical speak controllers link the model to the power source, this ensures that the model doesn't burn out 99:59:59.999 --> 99:59:59.999 and to improve the drone's durability 99:59:59.999 --> 99:59:59.999 DIY drone enthusiasts are even experimenting with 3D printed hybrid materials 99:59:59.999 --> 99:59:59.999 It's filament is made of, a mixture of PLA and carbon fibers 99:59:59.999 --> 99:59:59.999 so it is very stiff, it's very easy to work with 99:59:59.999 --> 99:59:59.999 With all of these design improvement, may be Amazon delivery drone could be a real possibility 99:59:59.999 --> 99:59:59.999 At the denser populated area, it's not all that feasible although from a logistic stand point if you had a fulfilment center, you know, 2 blocks away 99:59:59.999 --> 99:59:59.999 and you had a radius says you're going to deliver within it's actually very feasible 99:59:59.999 --> 99:59:59.999 That means that in the near future there might be more drones lurking in the mist 99:59:59.999 --> 99:59:59.999 For Scientific American I am Theresa Chong
