A team of scientists has developed “robot flies” about the size of a quarter that can perch on almost any surface. The perching works using static electricity. Each drone carries a tiny copper electrode on its head. When the electrode is energized, it creates a static charge that sticks the robot to a surface. Turning off the electrode sends the little drone back into the air. Perching is important because it makes the robots more energy efficient. Perching is up to a thousand times more energy-efficient than hovering in place, the researchers say. Read more about roboflies here at National Public Radio (NPR). |
