Painless Differentiable Rotation Dynamics

Magí Romanyà Serrasolsas, Juan J. Casafranca, Miguel A. Otaduy We propose the formulation of forward and differentiable rigid-body dynamics using Lie-algebra rotation derivatives. In particular, we show how this approach can easily be applied to incremental-potential formulations of forward dymamics, … Continue reading
