gumby-like flexible robot crawls in tight spaces

Scientists at Harvard have created a new type of flexible robot that is flexible enough to swing and crawl in small spaces.
This is the latest prototype in the growing soft fieldbodied robots.
Researchers are increasingly drawing inspiration from nature to create machines that are more flexible and versatile than metal-made machines.
Harvard team led by chemist George M.
The white edges borrowed from squid, starfish and other animals without hard bones form a small four
It reminds us of the leg rubber robot of the clay animation character Gumby.
Scientists have been tinkering in recent years-sometimes odd-looking --
Robot designed to squeeze hardto-
Reach the cracks after a disaster like an earthquake, or navigate the rugged terrain on the battlefield.
\"The unique ability of soft robots to deform allows them to go where they are traditionally rigid --
Matthew Walter, an expert in robotics at MIT, said in an email: \"Body robots can\'t . \".
Earlier this year, a team at the University of taftz showed off a 4-
A shape robot made of silicone rubber that can curl into balls and push forward.
The Harvard project, funded by Pentagon research, was published in the Journal of the National Academy of Sciences on Monday.
The new robot, which took two months to build, is 5 inch long.
Its four legs can be controlled separately by either manually or by a computer delivering air to the limbs.
This gives the robot a range of movements including crawling and taxiing.
The researchers tested the flexibility of the robot to make it in just three-
An inch from the surface.
Scientists use a combination of various movements to move robots 15 times through this tiny gap.
In most cases, it takes less than a minute from one side to the other.
The researchers ended up hoping to increase the speed of the robot, but were happy that it did not get rid of continued inflation and deflation.
Robert Sheppard, a Harvard postdoctoral fellow, said: \"It\'s hard enough to survive . \" He added that robots can walk on various surfacesO.
There are shortcomings.
Robots are tied to external power supplies and scientists need to find a way to integrate the power supplies before they can be deployed in the real world.
\"There are a lot of challenges with active mobile soft robots, and there are no simple solutions,\" said Barry Tom, a taftz neurobiologist working on Caterpillar robots, in an email.
Carmel magidi, head of the Soft Machine Lab at Carnegie Mellon University and robot researcher, said the latest robot is innovative, even if it was built on previous work.
\"It\'s a simple concept, but they get realistic biological movements,\" he said . \". ------
