China created tiny robot worms that could crawl inside the human body. South China Morning Post (SCMP) previously reported that scientists in Shenzhen successfully developed a machine that could penetrate the human brain.

The tiny robots are integrated with infrared radiation allowing them to contract their bodies by more than a third so that they can squeeze through tight gaps. It can change its color because of its transparent, temperature-responsive hydrogel structure, giving it invisibility in room-temperature water.
Scientists used a neodymium-iron-boron magnet to create its head, while its tail is constructed from a special composite material. Xi Tiantian said that it will be used for medical purposes. She explained that doctors can inject into the human body to deliver drugs or medicines to a targeted location, such as a tumor.
This can provide patients with fast recovery since the drugs it will deliver will only focus on the body part that needs it, reducing the risk of side effects. It was also explained that the robots can exit the body once it successfully delivered the medicines.
