Guinness recognizes Piccolissimo as world’s smallest self-powered flying robot


Professor Mark Yim and graduate student Matt Piccoli, creators of Piccolissimo.

Italian for “tiniest,” Piccolissimo is the brainchild of Matt Piccoli, a graduate student in professor Mark Yim’s ModLab. The robot comes in two sizes; the smaller weighs less than 2.5 grams and is about the width of a quarter, while the larger, steerable version is about 2 grams heavier and a centimeter wider.

The string of adjectives qualifying Piccolissimo as the “smallest” is necessary due to the concerted effort in miniaturizing flying robots. Harvard’s RoboBee, for example, is a few millimeters smaller than the steerable Piccolissimo, but is tethered to a terrestrial power source, limiting its range of motion.

Enabling directional control on such a tiny frame is an equally big challenge, but one that the ModLab is particularly equipped to address. One of the lab’s specialties is “underactuated” robots, ones that achieve the greatest range of motion with the fewest motors possible.
