EurekAlert  June 14, 2021 Researchers in Singapore created miniature robots by embedding magnetic microparticles into biocompatible polymers which are ‘programmed’ to execute their desired functionalities when magnetic fields are applied. They discovered the third and final principal vector of the magnetic fields, which is critical for controlling such machines. The robots have six degrees of freedom, rotate 43 times faster and they can be made with ‘soft’ materials hence replicate important mechanical qualities, ability to grip and precisely pick and place miniature objects. Other features include the remote control, ability to swim through barriers, and assemble structures, precise orientation control, […]
