Abstract
A method for calculating weight and center of gravity of an object lifted by a robot includes lifting an object, measuring a change in angle of each joint through an angle sensor provided for each joint of the gripper in the event of the lifting, and calculating angular velocity and acceleration of each joint, calculating, via a controller, acceleration of the object, measuring an upper pressing force and a lower pressing force using force sensors installed on the joints, and calculating, via the controller, the weight of the object using a vertical component of the acceleration of the object, gravitational acceleration, and the upper and lower pressing forces.
