"MESHWORM!!"

A new species in Robots clan-The Meshworm!

 Born at  MIT, Harvard University and Seoul National University, this creature...nah..a bot..hmm...better a earthworm like bot has revolutionized the world of robotics!!Its been named as "MESHWORM". Like an earthworm,it gets through hard-to reach space and traverse bumpy train.Unlike the previous robots,it doesn't have a bulky or breakable structure.

The movement of this miniature follows the simple science of contraction and relaxation of muscles generally  used by the worms to crawl.It has a mesh-like tube and artificial muscles developed from wires made of nickel and titanium.The nickel-titanium wire is wounded on the tube creating segments and a small current is passed through it.The alloy changes phase on heating up which is the reason for its stretching and contraction.As evident from the video,its not affected by the hammer or even if you throw it away!

Seems to be helpful for developing the next-generation endoscopes but exciting would be to see its usage to mobile phones or portable PCs!!
