“Drone Racing is a new high speed competitive racing sport. Skilled pilots fly quad-copter drones through three-dimensional courses at speeds up to 120mph. DRL drones are custom built for speed, agility, and performance. Pilots steer from the point of view of the drone by wearing First Person View (FPV) goggles that display a live image transmitted by an onboard camera. Flying a drone competitively at high speed in FPV is an intense, immersive experience.”
Sound like fun? Think you have the reflexes to compete against 20 somethings? I sure don’t! But don’t despair, you can play the DRL drone sim for free!
Recording motion in the form of moving pictures has gone through many stages. It started out as chemically processed film and was eventually replaced by analog magnetic tape. As time passed and technology advanced, the magnetic tape was replaced by digital memory devices with no moving parts and a much lower cost. Read the rest of this entry »
(The device)… consists of a thin sheet of resin–fiberglass composite, just a few centimeters across, segmented into 32 triangular panels separated by flexible silicone joints. Some of the joints have heat-sensitive actuators that bend 180 degrees when warmed by an electric current, folding the sheet over at that joint. Depending on the program used, the sheet will conduct a series of folds to yield the boat or airplane shape in about 15 seconds. The folding-sheet approach is an extension of the field of computational origami, the mathematical study of how flat objects can be folded into complex, three-dimensional structures.
