covering the week's top text doors it's like Linux bias researchers have developed an algorithm that could stop self-driving vehicles from getting into crashes and traffic jams the algorithm divides the ground beneath the machines into a grid the robots learn their position through technology similar to GPS and coordinate their own movements together through sensors that assess where there's free space to move Northwestern engineers Michael Rubenstein says the robots refused to move to a spot until that spot is free and until they know that no other robots are moving to that same spot they are careful and reserve a space ahead of time Rubenstein's team tested their algorithm on a swarm of 100 robots set up in their lab to cut out any distractions the robots were only allowed to sense three or four of their closest neighbors this restricted their vision it and it made the system easier to scale as the robots can interact locally without needing global information think about the impact of that so the advantage of a swarm of robots is that there is no centralized controller that can disrupt the whole system this allows them to work together to accomplish any task even if one of them breaks down this gives the system and obvious application in warehouse robots but Rubinstein believes it could actually also cut traffic and collisions for self-driving vehicles on the road he said quote by understanding how to control our swarm robots to form shapes we can understand how to control fleets of autonomous vehicles as they interact with each other
