Scientists make rotors that can merge to multicopter itself




A team of researchers at a Swiss university has built a multicopter. The flying machine can autonomously build from individual rotors, which communicate and collaborate.

The project, which was created by researchers at the ETH in Zurich, Switzerland developed , is called by the authors the Distributed Flight Array. This DFA consists of smart, single rotors, a kind little helicopter, which on the ground drive but can not fly autonomously. When they meet, they can attach themselves to each other and configure themselves to a flying platform. For each action would fly DFA take another random configuration.

The individual rotors connect with one another via magnets. They also communicate via infrared or physical pins that are in contact with each other. Thus, the directions of rotation of the rotors are matched to each other: the left half will have to rotate clockwise and the other, in order to eliminate each other’s torque. The rotors include equipped with sensors for altitude and distance and the DFA can stabilize itself in the air.

The researchers indicate that the immediately applicable utility of DFA small and that the platform is primarily intended as a research tool for cooperating robots. In the future could be. Certain characteristics, however, useful to robotics translated
