Figure Legend:
The 31DOF human linkage model with dimensions (L0–L13) and joint rotation axes (q0–q27) denoted by cylinders. Three additional degrees of freedom (q28–q30) capture the rigid body translation of the body. Specific segment lengths and mass values represent the values used in the computations of Sec. .
