Three-dimensional musculoskeletal model simulation for the motor skills optimization using the Open Dynamics Engine

Abstract

We previously proposed a training system that helps inexperienced athletes to acquire skills through a repeated comparison of their biological signals measured in real time to that of the signals produced by the optimization calculation using a musculoskeletal model considering the physical characteristics of each subject. We call this training system “cybernetic training” that refers to a feedback based signal produced artificially by optimization of the model calculations. However, using a model with many muscles, it is very difficult to calculate the optimal muscle activation signals to produce the desired motion. In this paper, we propose a three-dimensional rigid link model using the ODE with a reputation for high-speed computation, was studied for its optimization method.
