The Freefall Camera (FFC) is a robot that can be tossed out of a plane to autonomously track and capture video of skydivers doing tricks. At a predetermined altitude, the robot pops its steerable parachute and lands near specified GPS coordinates. The University of Nottingham researchers who developed the Freefall Camera presented their work at last week's International Conference on Intelligent Robots and Systems. From IEEE Spectrum:
Building a robot that can successfully control its position and terminal velocity relative to another falling object is not something that’s been done before. There are freefall cameras designed to work in microgravity, but that’s a much different challenge: this camera has to be able to maneuver in a 120 mph (190 km/h) stream of air, which is all about passive aerodynamics. To steer itself, the FFC uses four vertical ailerons to control yaw (and eventually horizontal position), along with a pair of retractable flaps that increase or decrease the robot’s drag to slow it down or speed it up. A GoPro does the recording while a CMUcam5 vision sensor tracks colored blobs to stay locked onto its subject...
The tests showed that the FCC could generally track a human within 0.25 meters vertically, and 12 degrees of the center of the camera’s field of view. Occasionally, the camera would get confused by backgrounds or bright lights, so the next incarnation of the system will use an infrared beacon for tracking instead.
Senior NASA photographer Bill Ingalls apparently set up his Canon EOS 5DS at an unlucky spot near yesterday’s SpaceX rocket launch. He placed it outside the pad perimeter yet the launch sparked a small brush fire that cooked the camera. “I had many other cameras much closer to the pad than this and all are […]
Daniel Kordan is a great photographer who travels to distant lands for stunning astrophotographs among other. Some of his stills are below, but his video of a trip to Greenland has his same eye for natural beauty.
Sean R. Heavey claims that Stranger Things used his storm cloud photo (top image) without permission in concept art (second image above) that eventually became a scene in the show. From Photographer: ‘Stranger Things’ Used My Storm Cloud Without Permission: Heavey says he realized that the cloud that appears in the Stranger Things episode looked […]
