GÖMBÖC FEATURES IN DRONE DESIGN
PRODUCTION
Cutting-edge drone design inspired by the Gömböc.
The GRASP laboratory at the University of
Pennsylvania is one of the world’s foremost
research and development centers for helicopter
drones. The lab’s team has pioneered to design a
bio-inspired flying robots with collective behavior.
Their latest breakthrough is super-stable pico-drone
capable of in-flight self-righting, designed by Yash
Mulgaonkar. The carbon-fiber composite exoskeleton
of the miniature robot was inspired by the Gömböc
shape. Although the Gömböc shape is very sensitive
and in case of a homogeneous body deviations
of 1/100 millimeter may destroy its mechanical
properties, the shape itself is a good starting point
for any kind of self-righting mechanism. The Penn
scientists are already working on its larger variant.

Gömböc’s are produced by using CNC (Computer
Numerical Control) milling technology. Manufacturing one
single Gömböc requires several hours of precision milling. Every
hundredth of millimeter counts for Gömböc-type of objects, so
we work with high accuracy level. The smallest change in the
process can have the harmful effect that the product will lose its
“gömböc-self”. Therefore, if we engrave a Gömböc, we have to
recalculate the whole self-righting shape to be able to balance
the mass inequalities.
