abstract     : We propose a complete process for designing, simulating, and fabricating
synthetic skin for an animatronics character that mimics the
face of a given subject and its expressions. The process starts with
measuring the elastic properties of a material used to manufacture
synthetic soft tissue. Given these measurements we use physicsbased
simulation to predict the behavior of a face when it is driven
by the underlying robotic actuation. Next, we capture 3D facial expressions
for a given target subject. As the key component of our
process, we present a novel optimization scheme that determines
the shape of the synthetic skin as well as the actuation parameters
that provide the best match to the target expressions. We demonstrate
this computational skin design by physically cloning a real
human face onto an animatronics figure.
