Microrobots overcome navigational limitations with the help of ‘artificial spacetimes’

Microrobots—tiny robots less than a millimeter in size—are useful in a variety of applications that require tasks to be completed at scales far too small for other tools, such as targeted drug-delivery or micro-manufacturing. However, the researchers and engineers designing these robots have run into some limitations when it comes to navigation. A new study, published in Nature, details a novel solution to these limitations—and the results are promising.
