This package directly builds upon Roy Featherstone's spatial_v2 library and his closely associated book.
New algorithms include:
- Methods to compute the Coriolis matrix (link) [all systems] and Christoffel symbols (link) (paper)
- Methods for assessing identifiability (link, paper)
- Methods to calculate second-order partial derivatives of Inverse Dynamics for multi-DoF joints (link)
New features include:
- Extensions of most algorithms (RNEA, ABA, CRBA, etc.) to address dynamic effects from motor rotors (link)
- Updated most algorithms (RNEA, ABA, CRBA, etc.) to handle multi-DoF joints (e.g., spherical or floating base) without needing specialized versions of the algorithms (link)
- Regressor calculation algorithms (link)
- Variety of tools for converting between different representations of orientation (link)
- Methods for computing the partial derivatives of Inverse Dynamics (link)
- Partial compatibility for complex-valued input arguments toward support of complex-step derivative comptuations in unit tests (including the complex step on matrix Lie groups link).
