This is a remarkable achievement.
Looks pretty near nanobotty to me!  :)

Quotes:
World’s smallest programmable robots think, swim, and sense temperature
using light.
These microscopic robots can swim, sense heat, work in groups, and run
autonomously for months on light power.

These microscopic swimming machines can sense their surroundings, make
decisions, and operate independently for months at a time. Barely visible
to the naked eye, each robot measures about 0.2 by 0.3 by 0.05 millimeters,
placing it squarely at the scale of bacteria and single-celled organisms.

“This is really just the first chapter,” Miskin said. “We’ve shown that you
can put a brain, a sensor and a motor into something almost too small to
see, and have it survive and work for months."  Future versions could carry
additional sensors, store more complex programs, or operate in harsher
environments, potentially transforming medicine and microscale
manufacturing.
