Sarah Bergbreiter: Why I make robots the size of a grain of rice
By studying the movement and bodies of insects such as ants, Sarah Bergbreiter and her team build incredibly robust, super teeny, mechanical versions of creepy crawlies … and then they add...

My students and I work on very tiny robots. Now, you can think of these as robotic versions of something that you're all very familiar with: an ant. We all know that ants and other insects at this size scale can do some pretty incredible things. We've all seen a group of ants, or some version of that, carting off your potato chip at a picnic, for example. But what are the real challenges of engineering these ants? Well, first of all, how do we get the capabilities of an ant in a robot at the same size scale? Well, first we need to figure out how to make them move when they're so small. We need mechanisms like legs and efficient motors in order to support that locomotion, and we need the sensors, power and control in order to pull everythin...
