New swarm of robots can fly without bumping into each other

Press Trust of India  |  Washington 

In a first, scientists have created a swarm of flying robots that can obey user commands and manoeuvre without colliding into each other.

The five swarm robotic quadcopters, created by researchers at the Institute of Technology in the US, zip back and forth in formation, then change their behaviours based on user commands.



The trick is to manoeuvre without smacking into each other or flying underneath another machine, researchers said.

If a robot cuts into the airstream of a higher flying quadcopter, the lower machine must quickly recover from the turbulent air or risk falling out of the sky.

"Ground robots have had built-in safety 'bubbles' around them for a long time to avoid crashing," said Magnus Egerstedt, professor at Tech.

"Our quadcopters must also include a cylindrical 'do not touch' area to avoid messing up the airflow for each other. They're basically wearing virtual top hats," said Egerstedt.

As long as the machines avoid flying in the two-foot space below their neighbour, they can swarm freely without a problem. That typically means they dart around each other rather than going low.

"We figured out the smallest amount of modifications a quadcopter must make to its planned path to achieve the new formation," said Li Wang, PhD student at Tech.

"Mathematically, that's what a programmer wants - the smallest deviations from an original flight plan," Wang said.

"Our skies will become more congested with autonomous machines, whether they're used for deliveries, agriculture or search and rescue," said Egerstedt.

"It's not possible for one person to control dozens or hundreds of robots at a time. That's why we need machines to figure it out themselves," he said.
