Robots are super interesting, but you probably shouldn’t start learning about them with a full-sized industrial SCARA arm or anything. Better to learn with something smaller and simpler to understand.

Cornell researchers in physics and engineering have created the smallest walking robot yet, and its tiny size is only a side-effect. Controlled by magnets and small enough to diffract visible light, ...

Scientists have created robots smaller than a grain of salt that can sense their surroundings, make decisions, and move ...

In a joint advance from the University of Pennsylvania and the University of Michigan, engineers have designed the smallest fully programmable autonomous robots ever built – ...
