Singaporean researchers have created miniature robots by embedding magnetic microparticles into
New miniature NTU robots move 43 timesfaster than analogues. In addition, they are made from "soft" materials - they float like jellyfish, and are also capable of grabbing, placing and sorting miniature objects.
According to the NTU team, miniature robotsabout the size of a grain of rice are used for expeditions to confined spaces that are inaccessible to existing robots. It is noted that makes them especially useful in the field of medicine.
Using a jellyfish-inspired robot, scientists have shown how it swims quickly through a tight hole in an obstacle.
Another robot that can grab objects, the researchers assembled a three-dimensional structure.
The operator remotely controls the movements of the robots using the program. It regulates the strength and direction of the magnetic fields generated by the electromagnetic coil system.
Details about the work of miniature robots are described in an article for the journal Advanced Materials.
