The newest frontier in robotics is almost invisible to the naked eye. Researchers have built a robot smaller than a grain of ...
Cell-sized robots can sense temperature, make decisions, and move autonomously using nanowatts of power—no external control ...
The robot, equipped with a solar panel -- like energy harvester and four wheels, is about the size of a penny, weighs as much as a raisin and can move about the length of a bus in an hour on a cloudy ...
A 301 mg soft robot jumps continuously under constant light without batteries or electronics, using snap-through buckling and self-shadowing to create an autonomous feedback loop.
