Estimating the center of gravity of an object using tilting by multiple mobile robots

Abstract

In transporting various objects by multiple mobile robots we need to change the formation of robots and posture of an object. This planning depends on the mass and center of gravity of an object. Here we discuss the accuracy of the estimation of the mass and the position of the center of gravity of an object. Particularly we propose a method for estimating the height of the center of gravity which cannot be estimated by only one measurement. Validity of this strategy is verified by means of a real robot system.
