Motorless microscale robots fly and steer using sound waves
Original: Engineers build motorless microscale robots that fly and steer using sound waves
Engineers have developed tiny robots that can fly and steer without any motor or onboard propulsion, instead using sound waves to control their movement. The approach removes the need for conventional moving parts at very small scales, where fitting motors and power sources is a major obstacle. Researchers say acoustic control could open the door to swarms of miniature flying robots for use in medicine, sensing and inspection tasks.
Why now: The novel motorless, sound-controlled propulsion offers a potential solution to long-standing limits on how small flying robots can be built.
