The study, published Dec. 18 in the journal Device, shows that swarms of microrobots controlled by rotating magnetic fields can perform tasks too complex for individual robots.
Roy has demonstrated abilities such as lifting objects 350 times heavier than a single robot and unclogging tubes that resemble blocked blood vessels. In one experiment, a swarm of 1,000 robots formed a raft to carry a tablet 2,000 times heavier than a single robot.
Composed of cubes containing magnetic particles, the robots use magnetic fields to assemble themselves and complete tasks.
Future developments will focus on improving their ability to navigate complex environments autonomously.
