Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these 'micro-bristle-bots' might work together to sense environmental changes, move materials -- or perhaps one day repair injuries inside the human body.
