A biomimetic robotic platform to study flight specializations
of bats

Dr. Alireza Ramezani
Postdoctoral Researcher, Aerospace Engineering
California Institute of Technology

Dr. Ramezani will discuss recent work on development of an Unmanned
Aerial System (UAS) with bat morphology called Bat Bot
(B2). An overview of hardware development, and a summary of
closed-loop flight control design for B2 will be presented. B2
weighs 93 gr and mimics morphological properties of bat wings.
Instead of using a large number of distributed control actuators, a
highly stretchable silicone-based membrane wings is implemented
that is controlled at a reduced number of dominant wing joints to
best match the morphological characteristics of bat flight. The dominant
joint movements in the bat flight mechanism are identified and
incorporated in B2’s design by means of a series of mechanical constraints.
The continuous surface and elastic properties of bat skin
under wing morphing are realized by an ultrathin (56 micron) membranous
skin that covers the skeleton of the morphing wings.

Alireza Ramezani is a postdoctoral researcher at Caltech’s Division
of Engineering and Applied Science (EAS). He received his Ph.D.
degree in Mechanical Engineering from the University of Michigan
in 2013. He received his M.S. and B.S. degrees in Mechanical Engineering
from ETH Zurich and Iran University of Science and Technology
in 2010 and 2007. His research interest lies at the intersection
of articulated robot locomotion (aerial and terrestrial) and applied
nonlinear control theory.
