An interesting video using a dog leash to make a drone follow you… no need for GPS, or other fancy tracking stuff…
At the Drones and Aerial Robotics conference in New York City this morning, aerial robotics postdoc Sergie Lupashin demonstrated a drone on a leash. The drone, which he calls the Fotokite, acts like a steadicam and does two things very well: fly places where you probably couldn’t stick a camera and then hover in place, filming. The leash adds stability, anchoring the drone.
