OpenSim Moco is a new part of the OpenSim project for solving optimal control problems with OpenSim musculoskeletal models. Moco can solve a wide range of problems, from estimating muscles forces to predicting new motions, without requiring users to have expertise in optimal control methods. Moco is created by the Stanford University Neuromuscular Biomechanics Lab, where OpenSim is developed.
