GÖMBÖC FEATURES IN DRONE DESIGN<br />
PRODUCTION<br />
Cutting-edge drone design inspired by the Gömböc.<br />
The GRASP laboratory at the University of<br />
P<strong>en</strong>nsylvania is one of the world’s foremost<br />
research and developm<strong>en</strong>t c<strong>en</strong>ters for helicopter<br />
drones. The lab’s team has pioneered to design a<br />
bio-inspired flying robots with collective behavior.<br />
Their latest breakthrough is super-stable pico-drone<br />
capable of in-flight self-righting, designed by Yash<br />
Mulgaonkar. The carbon-fiber composite exoskeleton<br />
of the miniature robot was inspired by the Gömböc<br />
shape. Although the Gömböc shape is very s<strong>en</strong>sitive<br />
and in case of a homog<strong>en</strong>eous body deviations<br />
of 1/100 millimeter may destroy its mechanical<br />
properties, the shape itself is a good starting point<br />
for any kind of self-righting mechanism. The P<strong>en</strong>n<br />
sci<strong>en</strong>tists are already working on its larger variant.<br />

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