colleagues, engineers and
computer scientists from
Dartmouth College have
built the smallest robot in
the world which is the
thickness of human hair
and shorter than the sharp
point of a thumb tack,
integrated in a small
package, wireless
powered and controlled.
However, the robot takes
over ten thousand steps a
second and continue their
motion for over half an
hour with no sign of
fatigue, with net motion
of over one foot in length.
That represents over 30
million steps; a human
taking that many steps
would go over half way
around the world.
