text: 'We present an interactive design system that allows non-expert users to create
animated mechanical characters. Given an articulated character as input, the user
iteratively creates an animation by sketching motion curves indicating how different
parts of the character should move. For each motion curve, our framework creates
an optimized mechanism that reproduces it as closely as possible. The resulting
mechanisms are attached to the character and then connected to each other using
gear trains, which are created in a semi-automated fashion. The mechanical assemblies
generated with our system can be driven with a single input driver, such as a
hand-operated crank or an electric motor, and they can be fabricated using rapid
prototyping devices. We demonstrate the versatility of our approach by designing
a wide range of mechanical characters, several of which we manufactured using
3D printing. While our pipeline is designed for characters driven by planar mechanisms,
significant parts of it extend directly to non-planar mechanisms, allowing us
to create characters with compelling 3D motions. '
