High Tech Drone Scarecrows Can Make Airports Safer

If you pay attention to airplane news — or you watched the film Sully — you know planes have problems with birds. Sully was about US Airways flight 1549 which struck a flock of geese and ditched in the Hudson river.  Engineers at Caltech say that was the inspiration for them to develop a control algorithm that enables a single drone scarecrow to herd flocks of birds away from airports.

Airports have tried a lot of things to discourage birds ranging from trained falcons to manually-piloted drones. Apparently, herding birds is harder than you would think. If you fly the …read more

Hands-On: Flying Drones with Scratch

I’ll admit it. I have a lot of drones. Sitting at my desk I can count no fewer than ten in various states of flight readiness. There are probably another half dozen in the garage. Some of them cost almost nothing. Some cost the better part of a thousand bucks. But I recently bought a drone for $100 that is both technically interesting and has great potential for motivating kids to learn about programming. The Tello is a small drone from a company you’ve never heard of (Ryze Tech), but it has DJI flight technology onboard and you can program …read more

Automate the Freight: Maritime Drone Deliveries

Ships at sea are literally islands unto themselves. If what you need isn’t on board, good luck getting it in the middle of the Pacific. As such, most ships are really well equipped with spare parts and even with raw materials and the tools needed to fabricate most of what they can’t store, and mariners are famed for their ability to make do with what they’ve got.

But as self-sufficient as a ship at sea might be, the unexpected can always happen. A vital system could fail for lack of a simple spare part, at best resulting in a delay …read more

Hackaday Prize Entry: Underwater Glider Offers Low-Power Exploration

[Alex Williams] created his Open Source Underwater Glider project as an entry to The Hackaday Prize, and now it’s one of our twenty finalists. This sweet drone uses motor-actuated syringes to serve as a ballast tank, which helps the glider move forward without the use of traditional propellers.

Unlike most UAVs, which use motors to actively move the craft around, [Alex]’s glider uses the syringes to change the buoyancy of the craft, and it simply glides around on its wings. When the craft starts getting too deep, the syringes push out the water and the glider rises toward the surface …read more
