Scientists at Argonne National Laboratory have created 'microbots' that can manipulate tiny objects:

The robots, which are only half a millimeter wide, are controlled via magnetic fields and can perform simple tasks such as opening their jaws or moving around a container of liquid.

They are among the smallest robots ever created.

According to the Department of Energy (DOE), which operates Argonne, the new robots demonstrate the ability to manipulate materials on a miniature level.

The creation of the robots, which are self-assembling and self-repairing, was funded by a DOE project to design active self-assembled materials.

Awesome.
