A little randomness improves the navigation of robot swarms in crowded environments

  • No comments
Researchers from the United States and the Netherlands have shown that controlled randomness in the movement path of robots reduces traffic jams and improves the rate of task completion, without the need for a powerful central computer or complex coordination.

Israeli study: Soft coral performs rhythmic movement without a central brain

A distributed neural “pacemaker” system has been discovered in the Red Sea Xenia umbellata: each arm beats independently but synchronizes with the others; the findings were published in PNAS and may change the understanding of rhythmic movement in evolution

Scientific discovery: researchers have seen phenomena from quantum mechanics in the movement of pendulums

The new system makes it possible to observe the phenomena that occur inside special "topological" materials by photographing the movement of pendulums using a normal camera
