Imagine tiny robots moving through your bloodstream, breaking down blood clots, repairing damaged cells, or delivering targeted drugs to tumor sites.

This isn't science fiction---it is the real-world potential of microrobotics, a field on the verge of revolutionizing robotics research and transforming medicine as we know it.

In episode #3 of my podcast, I sit down with leading expert Brad Nelson, Professor of Robotics and Intelligent Systems at ETH Zürich, to explore the fascinating world of robots at the smallest scales.
