The myoFinger mujoco musculoskeletal (MSK) model was created based on a biomimetic artificial robotic finger system [https://ieeexplore.ieee.org/document/6290710].
It is a simplified and intuitive model of a 4 Degree of Freedom (DoF) finger (MyoFinger, Figure 4A), which is actuated through a series of 5 simplified antagonistic muscle-tendon units.
