GÖMBÖC FEATURES IN DRONE DESIGN<br />

Cutting-edge drone design inspired by the Gömböc.<br />
The GRASP laboratory at the University of<br />
Pennsylvania is one of the world’s foremost<br />
research and development centers 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 sensitive<br />
and in case of a homogeneous 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 Penn<br />
scientists are already working on its larger variant.<br />

Gömböc models are produced by using CNC (Computer<br />
Numerical Control) milling technology. Manufacturing of 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 at very high accuracy. The smallest change in the process<br />
may result in a dysfunctional Gömböc shape. Therefore, if<br />
we engrave a Gömböc, we have to recalculate the whole selfrighting<br />
shape to be able to balance the mass inequalities.
