Rice Grain-sized Robots Controlled with Magnetic Fields

In the past few years, we have covered plenty of tiny robots here. NTU Singapore scientists have now developed miniature robots the size of a rice grain that can be controlled using magnetic fields. They can swim like a jellyfish. These robots can go through barriers, grip & assemble 3D structures, and move in all directions.

By varying magnetic fields, operators can control these miniature robots.
