Google Scraps Project Wing, Working on New Drone Design

(Source: Wall St Journal Blogs)  

Google has scrapped its initial drone design because it was difficult to control and is now working on a new version, according to Astro Teller, head of the Internet company’s Google X research lab.

Teller told the South by Southwest conference in Austin, Tex., that Google founders Larry Page and Sergey Brin encourage such failures, so researchers can learn from the mistakes and try different technologies and strategies.

In August, Google unveiled a drone-delivery system called Project Wing that the Internet giant was testing. The prototype had a five-foot single wing that sat vertically on the ground and then turned horizontal after take-off. The design was supposed to combine the benefits of vertical, hovering take-offs and landings with the speed of wing-based flying. In the test, the drones carried supplies including vaccines, water and radios to farmers in Queensland, Australia.

The drone was mechanically simpler than other types of drones, but it was harder to control, Teller said on Tuesday. It didn’t hover well in high winds and its cargo shifted too much when the wing moved up and down, he explained.

Google began working on drones in 2011. It’s not clear when it began experimenting with the single-wing design, but Teller said half the team “knew it was the wrong answer” after eight months. After 18 months, about 80% of the team thought this, he added.

The team debated whether to scrap the design or test it quickly in public. Brin told the team they had five months to make deliveries to real people, which wasn’t enough time to come up with a different design, so the team went ahead with the Australia test with their existing prototype, Teller said.
