Scientists at MIT and Stanford created a new type of tiny robot called a "rovable" that’ll travel over clothes. The little bots have magnetic wheels on either side of a garment that keep them anchored and moving, as well as a 100mAh battery, microcontroller, and a small antenna so they can communicate with the computer directing them. They’re also relatively autonomous, so they can direct themselves back to their home base for wireless charging.
The rovables are an adorable proof-of-concept. The researchers behind their creation think people might want to use them to create interactive clothing or jewelry. Maybe when a wearer gets a phone call, the rovables could move closer to his or her neck to double as a microphone. Or maybe the rovables could create a moving, massive display. Personally, I love the idea of a robot traveling around my body making me a better and way cooler-looking human.
