  abstract = {This article distinguishes configuration, state, input,
    task and statistical dimensions in movement models. It relates
    mechanical constraints, passive dynamics, contraction, recursive
    dynamics algorithms and local trajectory optimization without
    treating them as equivalent reductions or evidence of a neural
    mechanism.}
