Rapid Bipedal Gait Design Using C-FROST with Illustration on a Cassie-series Robot [link]Paper  abstract   bibtex   
One of the big attractions of low-dimensional models for gait design has been the ability to compute solutions rapidly, whereas one of their drawbacks has been the difficulty in mapping the solutions back to the target robot. This paper presents a set of tools for rapidly determining solutions for "humanoids" without removing or lumping degrees of freedom. The main tools are: (1) C-FROST, an open-source C++ interface for FROST, a direct collocation optimization tool; (2) multi-threading; and (3) following the lead of the manipulator community, removing the Coriolis terms in the model. The results will be illustrated on a 20-DoF floating-base model for a Cassie-series bipedal robot through numerical calculations and physical experiments.
