THESE SNAKES WILL
Snake robots are cool. They slither.
They swim. They shoot lasers with their
mouths. Researchers often say that
snakebots are great for search and
rescue applications. You send one into a
disaster site and use its cameras to see
what's going on there. However, with all
the slithering and rolling and undulating,
watching through a snakebot's eyes might
be a nausea-inducing experience.
Now, the folks at the CMU
Biorobotics Lab might have a solution.
Their snake robot can point its head in a
desired direction while climbing on a
pole. The whole body moves; the head
Snake robots can use their many internal degrees of
freedom to thread through tightly packed areas, accessing
locations that people and machinery otherwise cannot.
Moreover, these highly articulated devices can
coordinate their internal degrees of freedom to perform a
variety of locomotion capabilities that go beyond the
capabilities of conventional wheeled and recently developed
legged robots. The true power of these devices is that they
are versatile, achieving behaviors not limited to crawling,
climbing, and swimming.

BTW, the snake names are: Uncle Sam, Frostbite, Molly,
Spooky Snake, and Pepperoni.
