3D-printed robot moves through the human body with the help of wings-fins. And delivers medicine to the affected organ.

The robot is covered with a layer of cardiomyocytes (heart cells), and its wings are covered with a photosensitive hydrogel.

When cells work in unison (as in the heart), they force the flexible tail to move up and down. This, in turn, causes the robot to move forward in a liquid medium.

He also uses wings-fins, which are active while the robot is in the dark.

During laboratory tests, the robot is successfuldelivered targeted delivery of drugs against cancer cells. Currently, researchers are working on a system that will allow them to fold each wing separately, increasing the maneuverability of the device.

Previously promising research managementProjects of the US Department of Defense (DARPA) announced a competition for the concept of a military robot, in which the brain of a flying insect will be responsible for the calculations.
