2-Legs and Torso, OpenSim  Monitor Package
This is a variation of the single leg model described in the attached publications. This model includes 2 legs and a torso with the mass properties of a composite head-arms-torso (HAT).

Two legs and a HAT, version 2.1
April 12, 2011

This version uses the same lower limb muscle architecture and geometry as the single-leg version, with modifications to make it appropriate for use in whole body studies of movement and computed muscle control (CMC) simulation. Two strength levels of model are available, as well as a version with arms. Click "Notes" for a complete list of features. Version 2.1: Corrects a bug in the knee_angle_r and knee_angle_l ranges. Hides wrapping surfaces by default. Version 2: contains an update to the right and left patella joints to work around an issue using the Scale Tool on translational coordinate coupler constraints in OpenSim. See Notes for more details. Thanks to Samuel Hamner and Matt Demers for correcting this issue. To use the version with arms, please also cite: Hamner, SR, Seth, A, and Delp, SL, Muscle contributions to propulsion and support during running.
