Each robot costs only a single penny to manufacture. The robots could help advance everything from nanotechnology ...

The device advances medicine toward a future that might see tiny robots sent into the body to rewire damaged nerves, deliver ...

Cell-sized robots can sense temperature, make decisions, and move autonomously using nanowatts of power—no external control ...

The newest frontier in robotics is almost invisible to the naked eye. Researchers have built a robot smaller than a grain of ...

A group of Chinese researchers has created a robot with a brain made of human stem cells. The technology is technically a "brain-on-a-chip," and the researchers have been working to train the robot to ...

Could a robot smaller than a microorganism actually think on its own? Well, scientists from the University of Pennsylvania ...

Robots small enough to travel autonomously through the human body to repair damaged sites may seem the stuff of science ...

Microscale swimming bots take in sensory information, process it and carry out tasks, opening new possibilities in ...

Researchers at the University of Pennsylvania and University of Michigan have created the world’s smallest fully programmable ...

A microrobot can operate independently in liquids for months. The development effort was high, but the costs for the robot ...

In a tiny laboratory pond, a robotic stingray flaps its fins and swims around. Roughly the width of a dime, the bot dashes distances multiple times its body size. It easily navigates around corners ...

It’s a bizarre sight: With a short burst of light, a sponge-shaped robot scoots across a tiled surface. Flipped on its back, it repeatedly twitches as if doing sit-ups. By tinkering with the light’s ...
