Fotokite: A quad on a tether | In The Making
“Dr. North headed to Zurich to meet Fotokite founder Sergei Lupashin to see a flying UAV with a tether. The one-of-a-kind leash not only provides a direct connection to the flying robot, but also serves as a visual accountability mechanism–so that those around know who the drone belongs to.”
I particularly like this: "If you don’t crash, you don’t learn."
