It's not your common rubber snake for the foremost time, a
soft-bodied robot is capable to slither around motorized by air. It can attain
a leisurely top speed of 19 millimeters per second.The strength of the model,
developed by Cagdas Onal and colleagues since the Massachusetts Institute of
Technology, are minute tubes made from spongy poly
mers called elastomers that
line the snake's four segments.
To imitate a snake's motion, an involved computer in the
robot's tail control a compressor that changes air force in the elastomer tube.
Air passing throughout the body creates a travelling wave that increases in
amplitude with greater pressure . Valves at the joints open and close to create
the robot snake rise and fall.
