bouuu it gives me cold in the back stuff like that me!
Developed by a team of researchers from the University of Pennsylvania, drones a few centimeters in diameter can move without using GPS and fly in a squadron in perfect coordination. A beautiful technical feat whose applications would be interesting.
At a TED (Technology, Entertainment, Design) conference, Vijay Kumar, director of the Department of Mechanical Engineering and Applied Mechanics at the University of Pennsylvania caused a sensation with his miniature drones.
These robots can fly inside buildings completely independently and without the use of GPS. Kumar and his team started from a commercial drone model and equipped it with sensors (accelerometer, gyroscope) and processors. It has four rotors, weighs fifty grams, measures 20 cm in diameter and consumes 15 watts of electricity. One of the processors on board the drone performs 600 operations per second to determine what movement is to be performed and acts accordingly on the speed of the different rotors to move up, down, forward or backward. "By reducing the scale, the robot becomes naturally agile," says Vijay Kumar, adding that this reduces inertia so that it performs its movements much faster. As a result, the minidrone can rotate 360 degrees in less than half a second.
