Hopefully this never gets reverse-engineered by AI.
Panagiotis Artemiadis, director of the Human-Oriented Robotics and Control Lab at Arizona State University, developed mind-controlled drone swarms by tracking electrical activity in the brain. When the cap-wearing human pictures the quadcopters doing a task, they respond. One person can control up to four drones this way, with the intention of eventually adding multiple people to control larger swarms.
The brain is interested in teasing out patterns in collective behaviors, Artemiadis said, according to the ASU blog — a surprising finding, since controlling the movement of our own bodies doesn’t require this kind of swarm-understanding. He hopes to develop this tech for search-and-rescue missions.
