Abstract: Disclosed are systems and methods for controlling walking of a wearable robot, which provide walking assistive power as if something were pulling the wearer of the robot from the front or pushing the wearer from the back, by applying the force of a virtual spring, whereby the wearer may comfortably walk. The systems for controlling walking of the robot include: a walking mode determination unit configured to determine whether the robot is walking; a virtual spring force calculation unit configured to calculate the force of a virtual spring of which one end is connected to the robot and the other end is connected to a target point in front of the robot based on the walking direction; and a joint driving unit configured to drive each joint of the robot using torque calculated based on the force of the virtual spring, which is calculated by the virtual spring force calculation unit.

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.
