An optimization model was created in OpenSim Moco 0.4.0 to simulate manual lifting and unloading. A subtask-based multi-objective function method was used. The physical model developed in OpenSim 4.2 includes a foot, shank, thigh, pelvis, torso, upper arm, forearm and hand.
The corresponding paper is under review. More detailed information and source code will be available months later.
