Micro robot takes an object that you swallow

Robots wrapped in pork shells carry magnets into the body to suck foreign bodies into the gastrointestinal tract, then use wound healing drugs.

According to MIT News, the boy Emmett Rauch, one year old, vomited blood because he swallowed a round battery of the watch. The doctor must have emergency surgery to remove the battery from the baby's body. Then the boy's throat was "like a firecracker" by a doctor, because the chemical from the melted battery penetrated into his throat and gradually destroyed the cell. Although the battery was taken out, it took many years and dozens of surgeries later, Emmett's windpipe was renewed and could breathe normally.

In the United States, an average child has 3 hours of swallowing the battery in the abdomen, mostly small round clock batteries. The mortality rate is not great, but the complications are very serious, as is the case with the boy Emmett.

Recently, Massachusetts Institute of Technology (MIT) researchers have been working on creating a micro-robot that can be inserted into the body to remove objects you've missed, including batteries. The device is encapsulated in a capsule.

When entering the body, the robot will self-extract as an open sheet of paper to return to the device shape. They are controlled by a doctor from the outside. The device uses magnets that attract trapped foreign bodies and are carried out through the digestive system. The robot then moves around the stomach lining to treat small wounds with medication.

The team member Daniela Rus said that in order to control and move the robot inside the body, a small device system that is wirelessly controlled from the outside is needed. Unable to use metal and plastic to build this robot, scientists use hard pork (hard-shelled shells outside the fresh sausage) to create a coating over the robot.

Scientists say the next step will be to add more sophisticated sensors to help the robot work itself without external controls. It is expected that robots will be tested on animal bodies first.
