This talk will address nanorobotics, an emerging area within nanotechnology. We will attempt to answer the
fundamental questions of Why?, What?, and How? for this new field. We will discuss automatic manipulation of
molecular-sized objects; sensors, actuators and other components and systems for nanorobots; and coordination and
programming of swarms of nanorobots. The image of the current state of nanorobotics that will emerge from this
survey is that of a highly interdisciplinary, vibrant, and rapidly evolving and growing field with remarkable future
potential, but also with major challenges ahead.
