Researchers in Germany have developed a robot that is about a seventh of an inch long and looks at first like no more than a tiny strip of something rubbery. Then it starts moving.
The robot prototype is small enough to move around in a stomach or urinary system, said Metin Sitti, head of the physical intelligence department at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, who led the research team.
What is most unusual about the research, Dr. Sitti said, is that such a “minimalist robot” can achieve “all different type of motion possibilities to navigate in complex environments.”
