The above image is a shot of Georgia Tech's latest robot posed next to a penny. The 3D-printed bot is roughly two millimeters in length — or about the size of the world's smallest ants, per the school. The tiny devices are designed to move using vibration from a variety of sources, ranging from ultrasound to more traditional speakers.

With the proper source, the bristles allow them to move four times their own size in roughly a second by moving the legs up and down. Different-sized legs react differently, responding to a variety of different frequencies. The actuators that generate the vibration are outside of the robot, however, as batteries small enough to be housed on their bodies simply don't exist.

    This is just a fancier version of the Bristlebot [evilmadscientist.com] (video [youtube.com]).
