ESTIMATION OF MASS MOMENT OF INERTIA OF HUMAN BODY, WHEN BENDING FORWARD, FOR THE DESIGN OF A SELF-TRANSFER ROBOTIC FACILITY

Abstract

Knowledge of Mass Moment of Inertia of human body and its segments are necessary for various problems in biomechanics and its applications. This paper focusses on the estimation of Moment of Inertia of a human body when bending forward, which is needed for designing a robotic self-transfer facility for elderly and disabled. This paper also covers a brief review on studies of different anthropometric data like mass of the body segments, Centre of Mass, radius of gyration, etc. Using these data and certain assumptions, Mass Moment of Inertia of human body bending forward is estimated by applying laws of basic mechanics. This estimated value is then validated using a solid modelling CAD software.
