swallow this robot: foldable droid could mend stomachs

There may not be many occasions where you want to swallow a small robot.
But what if, before there is no trace of decomposition, such an edible robot can work in your body, target foreign objects or repair internal wounds?
A group of researchers at the Massachusetts Institute of Technology have proposed a new minimally invasive approach to perform tasks in the human body using biological content and biodegradable micro-robots.
The design of the robot is inspired by the Japanese origami art origami.
Mainly made of dry pig intestines (
Commonly used sausage casings)
These small robots look like a cross between a caterpillar and an accordion.
Researchers say a tiny magnet can allow them to be manipulated by an adjustable external magnetic field. [
The weirdest six robots ever.
The researchers have shown origami.
Shuhei Miyashita says inspired robots can swim, climb and load twice their weight, but creating an edible device that can be operated in the stomach suggests that he is part of the MIT development robotics team, but is now a lecturer in intelligent robotics at the University of York, UK.
\"The trickiest problem we have to solve is to have robots work in such unpredictable environments,\" Miyashita told Live Science . \".
\"The design of the robot has been re-developed
This way, when reversed, it can still walk and can correspond to changes in the anatomy of the stomach.
\"Building a tiny robot at the center of the robot\'s layered structure is a material that shrinks when heated.
When this happens, a carefully placed slit cut in the outer layer causes the initially flat structure to fold into a series of boxes
The researchers said it was like a fragment.
This design allows the robot to rely on so-called \"stick-
\"Sliding\" motion in which part of the robot is glued to the surface due to friction in some motion, but when the body of the robot is bent, the weight distribution changes, they will
But because this particular robot is designed to work in a fluid
The stomach-filled team redesigned the robot to make it more like a fin, so that it can also provide thrust by pushing water, effectively allowing the machine to swim and crawl.
\"It is very important to see such a small robot start at the same time [or movement]
\"Biodegradable,\" said Wang Hongzhi, professor of material science at Donghua University in China, who is engaged in self-researchOrigami-
But not involved in the new study.
\"It has a lot of potential applications in healthcare.
\"How it worked in a paper published at the IEEE International Conference on Robotics and Automation, held in May 16 --
The research team from the MIT lab of computer science and artificial intelligence in Stockholm, Sweden, described how they made a synthetic stomach to test the device and designed a two
Assume the step-by-step process of removing the swallowed watch battery.
Scientists have also shown how robots can repair wounds left by batteries. [

Part of the stomach and esophagus is lined with a silicone rubber mold that matches the true shape and physical propertieslife stomach.
The synthetic organs are then filled with liquid simulating the properties of gastric juice.
In this study, one of the robots was wrapped in pills --
Capsule size of ice.
After the device reaches the stomach, the external metal coil array produces a magnetic field that interacts with the robot\'s magnet and can be tuned to allow the capsule to roll towards the incoming watch battery.
The magnet attaches the capsule to the battery, and when the robot rolls off again, it removes the battery from the stomach lining.
The researchers say robots and batteries naturally drain from the digestive system.
The second robot is then taken into the body in the same way, but this time, the ice will melt and the robot will unfold.
The same magnetic array is used to guide the robot to reach the wound, which the robot will cover before the wound finally dissolves.
Scientists say the structure of the robot also includes a soluble layer soaked with drugs that help heal.
Larry Howell, professor of mechanical engineering at Brigham Young University, Utah, works on origami
This new study marks a valuable step in creating robots that can perform medical procedures in the body.
\"The idea of taking the robot into the ice bag for initial delivery and making it biodegradable for subsequent decomposition has the potential to reduce the length of time
The term has a greater impact than some surgical alternatives, \"Howell told Live Science.
However, Miyagi says it may take at least six to eight years for these robots to reach the clinic.
Control accuracy needs to be improved, he said, adding that strict animal and human testing is needed first.
