"The HEXBUG Nano is a tiny, collectable,
micro robotic creature that uses the
physics of vibration to propel forward and
explore its environment. Powered by a tiny motor,
and 12 fixed, angular legs, the industrious critter
traverses the ground beneath it and quickly navigates
through the most complex mazes.
Possessing an uncanny sense of balance,
it can even flip to its feet and zoom forward
when turned on its back! When coming into
contact with an object in its path,
the energetic insect will switch directions
and scurry away on a new path due
to its persistent random behaviour."
Just over 1 and half inches.
