This Tiny Robot Can Crawl, Swim, and Deliver Drugs Inside the Human Body

Only four millimeters in length, Germany's millirobot can be swallowed or injected into the body, then controlled with magnetic waves.

The soft millirobot climbs on the water meniscus by changing its body curvature and lands on the solid surface. Next, it encounters a large obstacle and traverses it fast and easily by jumping over it, and walks on the surface after landing. The dashed line shows the direction of the robot motion. | Max Planck Institute for Intelligent Systems
