Generalized Biped Walking Control

Line: 175 to 175

In general, the paper's writing style is clear and logical. The specific contributions, methodology, and limitations of the control system are laid out in the introduction, which helps provide a roadmap for the rest of the paper. One evalution that may have been helpful is a quantitative comparison of the "naturalness" of their gaits compared to motion capture data, as in "Optimizing Walking Controllers". Do the different gaits of varied characters reflect real-world differences correctly (at least for the physically possible characters)?

Contribution: Propose a new control strategy for physically simulated walking motions that is simple and generalizable. Each of the 4 components that composes it is clearly explained, justified, and its relevance tested.

Evaluation:It seems like they tested their system in a variety of scenarios and while performing different tasks or after various bodily deformations. But, as is usually the case, they do not provided any comparison to real data (motion capture in particular) neither visual nor numerical.

Reproducibility: An open source implementation of their project is provided, which is basically the best one can hope for in such cases. However, they clarify that this is "one implementation" and that they use various parameters "in their results".

Improvements: The authors acknowledge themselves that their characters cannot move at high speeds (i.e. fast motions make the characters fall over). There is no comparison to real data, nor does there seem to be a real measurement of robustness.
