Abstract
An apparatus and a related method are used to simultaneously calibrate a center-of-gravity and a moment-of-inertia. The apparatus includes: a motor rotated with a prescribed velocity; a tachometer installed at the motor for calibrating an angular velocity of the moto; a fixed plate which is installed at the upper portion of rotation axis of the motor and has a plurality of parts fixing units; a motor driver connected to the motor for controlling the driving of the motor and for calibrating a current value flowing into the motor; and a processor connected to the motor driver and the tachometer for calculating a center-of-gravity and a moment-of-inertia of a part by using the calibrated angular velocity and current value.
