Nothing a .22 couldn't solve. If Amazon delivered a package that way to my house, the octocopter would probably crash into the 150ft trees, or if it made it to the ground, I would grab the octocopter and reprogram it for my own purposes. I'm probably not quick enough to grab it before it takes off again, but the local dogs will certainly do it for me. Dropping the package from altitude doesn't seem like a great idea. Maybe a funnel and chute mounted on the roof? Has anyone at Amazon actually thought about how this would really work among the GUM (great unwashed masses)? If the rough calculations in the article are approximately correct, each octocopter will need to recharge between deliveries, making the cycle time rather long. Prediction: The USPS will soon have a similar idea for letter delivery as a cost saving measure. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Prediction: The USPS will soon have a similar idea for letter delivery as a cost saving measure. Wouldn't they just cycle units between charge and run over a larger fleet? Hardware is cheap, payroll is expensive. Avoiding wires, trees and buildings is established technology now. And you get mostly direct-line travel which has benefits I would assume. Drones don't mind early and late home delivery either which is a burden for drivers. So far, so good, maybe. I thought about delivery confirmation, maybe solved with face recognition camera. A robot calls to say the drone is at the door; open it, receive parcel. Thought about inclement weather, probably addressed with sealed plastic wrappers. Service limits would preclude delicate glass things, flammable liquids, eggs and tomatoes probably. These are workable areas all. Then I thought about all the bonehead things your average citizen does to subways, rental cars, public washrooms etc and decided this may be an impractical idea given the citizenry . Which doesn't even bring up our predilection for large often specious legal claims. I wish them well. Even in failure we'll all learn something. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

The majority of the racket would be them crashing into each other if there are a lot of them. The Associate Professor of Physics at Southeastern Louisiana University could have saved himself some calculation time by looking at what is on the market already. The payload and endurance are already commercially available, at a cost of a few tens of thousands (quid or bucks, makes no difference here). Control, yes, if you know the GPS co-ordinates of where it's going it can get very close. They can land themselves within 1 metre *provided* the GPS signal is good all the way to the ground. If it's not, or if there are any home Wi-Fi installations blocking the control signals at the target end then crashes are going to be frequent. Unless Amazon can carve themselves a dedicated hole in the radio bands and no-one comes along to steal it (such as the CB-ers if they're still around). Shooting them down isn't going to be easy, they are very hard to see even with the controller in your hand, and judging range is very tricky. (As an exercise we try to land ours on a declared spot about 50m away. And rarely get within 5m of the spot. That's knowing where it is and controlling the direction it's flying in.) What else? It's going to have to fly high enough to be clear of all ground obstacles, but low enough that the aviation authorities consider it out of their airspace. That's less than 400ft above ground in the UK. OK, so add a sonar altimeter, at a price. The value of the extra weight and the increased battery capacity to power the device is more expensive than the monetary cost. Technically it's quite do-able to get the thing hovering at 390ft above the delivery point. Getting it down in one piece where the recipient can retrieve the payload is the hard part. And having something with the value of a UPS van delivering just one small package an hour. If Jeff's dogs don't get it.... Mike |
