Answer 1

Erica is the latest invented robot

Answer 2

South Korean scientists have developed tiny robots that don't need an engine or battery to power their movements. But it's not perpetual motion. Instead, the robots run on environmental humidity, absorbing the moisture in their surroundings to be powered by water.

In a new paper in Science Robots, the scientists from Seoul National University describe the advantages of microrobots and how their so-called hygrobots could increase their usage. Microrobots can already help people have children and pull cars, but they're limited by the number of power sources available to them.
