Successful Silicon Valley drone startup Matternet doesn’t have the name-brand recognition (or deep pockets) of tech titans like Google (GOOG) or Amazon (AMZN). But while those companies have in recent months dominated the public conversation about using drones, Matternet has quietly deployed its own delivery drone technology in real-world scenarios in some of the world’s hardest-to-reach areas.

That’s right: robots are about to deliver our mail.

The three companies are currently researching the practical uses that drone technology could offer, and the business case to support such a development. The possibilities range from internal logistics to the delivery of consignments over the last mile.

Announcing Matternet ONE, the first smart drone for transportation, which realizes the vision of sending things through the air — magically, with the touch of a button. We believe that Matternet ONE has the power and simplicity to disrupt the last-mile logistics industry, transforming the way we get or give access to things locally.

They still aren’t delivering Amazon packages. But in Haiti, Bhutan, Papua New Guinea and the Philippines, drones have helped rescue natural disaster victims – and transport medical samples and supplies

The centuries-old disease is crippling communities in one of the world's most untamed wildernesses. Now unmanned aerial vehicles could bring treatment to the country's far-flung reaches.

When Andreas Raptopoulos and his team got stuck in a 20-truck convoy completely marooned in mud while navigating between villages in Papua New Guinea, it was incredibly frustrating. It was also a validation of his work.

Silicon Valley sweethearts like ride-sharing service Uber are entering the fast-food delivery fray as others like Matternet develop futuristic drones.

MSF and US Company Matternet trialled the use of small quadcopter Unmanned Aerial Vehicles (UAVs) to transport sputum samples of patients with suspected TB from remote health centres to Kerema general hospital for testing as well as possibly transport results and treatments back to the facilities.
