Ingestible origami robot


A team of researchers at MIT and elsewhere have developed a tiny origami robot that can unfold itself from a swallowed capsule to complete specific tasks within the body. The robot can remove foreign objects, it can patch wounds, or it can deliver medicine at designated locations. This new, ingestible robot builds on the teams previous work on mini origami robots, however the design of its body is significantly different. The challenge with with designing an ingestible robot is finding biocompatible materials that are easy to be controlled and amenable to the types of operations that are needed of the robot. To address this challenge the researchers tested about a dozen different possibilities for the structural material before settling on the type of dried pig intestine used in sausage casings. To demonstrate how the robot works, the researchers folded the structure into a capsule made of ice. The ice capsule travels down the esophagus into the stomach, where the ice melts away and the robot unfolds to its functional form. At this point, the robot can be controlled by an external magnetic field to do work such as the removal of a foreign object from the body. For example, every year, 3,500 swallowed button batteries are reported in the U.S. alone. The tiny batteries are digested normally but if they come into prolonged contact with the tissue of the esophagus or stomach, the batteries can burn the tissue and become embedded. Now, using the teams new robot, the battery could be removed without surgery. Once inside the stomach, the robot could be directed to attach to the battery. It could lift the battery from the stomach coating and then eliminate it through the digestive system. Next we would like to do in vivo experiments. We would also like to add sensors to the robot, and redesign the robot so that it is able to control itself without the need of an external magnetic field.

  1. We're one step closer to nanobots with AI that will take over the human body and destroy humanity as we know it!

  2. two problems, so we have to swallow a ice cube (that's hard)…. pork intestines seriously…. what about vegetarians?

  3. Think I read this wrong, I thought it was a robot that made ingestible origami, I guess the actual thing makes more sense though.

  4. right now it's no robot at all. You move the thing with magnets manually. It's a magnetic controlled tool. I think it's quite cool but it's no robot and the next evolution step mentioned is far, far, far beyond this technology.

  5. +Use J to go back 10 seconds. K to pause the video and L to jump forward. videos. You're welcome.

  6. I don't get how this is a robot, it is a magnet connected to pig intestine… I didn't know that when I made origami swans that I was making robots.

  7. what would the visit to the doctor of ice be like? do they do it right in their office, or is it still more like a OR? And what do they do like how do they make the magnetic field outside?

  8. Cool Story Bro but….. that's not a Robot.

    Not

    even

    A

    Little

    BIT……. commnet TYSON FURY is a crabstick if you read this 😀 xx

  9. What an interesting advancement… could change the way invasive digestive surgery is handled in the future.

  10. lol their target market is so small, it's almost not worth even making it lol (but still cool idea)

  11. I'm guessing you'll need to swallow another "robot" to dislodge this useless piece of shit when it gets stuck in your stomach after it's done humping the battery.

  12. Origami has been really helpful to us eh. Isn't that not what we used to in order to fold the satellites solar panels?

  13. Omg I have a great idea attach guns to its person with cancer swallows 1million of them with tiny guns than when in u they can have a war with the cancer lol😂😂😂😂😂😂

  14. Oh, no…You swallowed a toxic battery, and it became stuck
    Lets put a toxic magnet inside of you to get it out.
    Oh it got stuck too….
    Welcome to MIT

  15. But if you're using such a powerful magnetic field, why don't you just pull the batteries out using a magnet? Like attached to a string that they swallow or something. Not fun sounding, but MUCH simpler than a robot.

    (Ik this only applies to the battery example, but it's what they used so it's what I'm using)

  16. Your tutorials are pretty damn good! I liked and subscribed 😉 Maybe check me out! I do the same type of videos!

  17. the "robot" was still in pill form when it stuck to the battery. it didnt have to move at all. im not understanding the demonstration.
