German scientists have developed a microrobot with spiked legs that can move inside the intestines and deliver valuable cargo - medicines and sensors.

The dimensions of the robot are only 3.7 by 1.5 millimeters, but it is able to carry a load three times its own volume and up to 20 times its own weight. It also works autonomously.
