Identification of Human Inertia Properties Using a MomentumBased Approach
This paper presents a momentumbased approach for identifying the barycentric parameters of a human body. The human body is modeled as a multiple rigidbody dynamical system with a treetype topology using the principle of impulse and momentum. Since the resulting impulsemomentum equations are line...

description:  This paper presents a momentumbased approach for identifying the barycentric parameters of a human body. The human body is modeled as a multiple rigidbody dynamical system with a treetype topology using the principle of impulse and momentum. Since the resulting impulsemomentum equations are linear in terms of the unknown barycentric parameters, these parameters can be easily solved using the leastsquare method or other wellunderstood solution techniques. The approach does not require measuring or estimating accelerations and internal forces because they do not appear in the impulsemomentum equations and, thus, the resulting identification procedure is less demanding on the measurement and also less sensitive to measurement errors in comparison with other existing methods derived based on NewtonEuler or Lagrangian equations. The momentumbased approach has been studied by dynamics simulations with the consideration of possible measurement errors. The study...
