Abstract:
Methods and corresponding systems that are useful in design and fabrication of kinetic wire mechanisms or characters. The method includes a computational technique for the design of kinetic wire mechanisms tailored for fabrication on consumer-grade hardware such as a desktop CNC bending device. The method takes as input a skeletal animation of the mechanism to be fabricated and estimates, from the skeletal animation, a cable-driven and compliant wire structure, which matches user-selected keyframes. To enable localized deformations, the technique involves shaping the mechanism's body (i.e., the wire) into functional spring-like entities at a set of locations along the length of the mechanism's body. The method involves determining where on the wire body to place these spring-like entities, determining which types or configurations of spring-like entities should be placed at each of these locations, and optimizing parameters of each user-selected spring-like entity for use at the locations on the wire mechanism.
