摘要： Disclosed are a robot arm having high back-drivability to interact with a human being, which is safely stopped, and a method of controlling the robot arm. When the operation of the robot arm having high back-drivability to interact with a human being is converted into a safety mode due to the occurrence of an emergency, in which the operation of the robot arm is stopped, only a torque having a degree to compensate for gravity applied to the robot arm, i.e., only a torque to maintain the kinematical position of the current state of the robot arm without falling of the robot arm due to gravity, is outputted to control the robot arm as if the robot arm is in a weightless state, thus being capable of safely stopping the robot arm.

摘要： There is provided a robot, which compensates for the angle of a joint, bent due to external force, using a redundant degree of freedom of the robot, and a method of controlling the same. The method includes sensing a bending angle of a joint due to external force or a torque applied to the joint, comparing the bending angle of the joint or the torque applied to the joint with an allowable safety reference value; and adjusting the bending angle of a higher-level joint of the joint using a redundant degree of freedom of the robot, when the bending angle or the torque reaches the allowable safety reference value, thereby compensating for the excessively bending angle of the joint and thus being capable of safely controlling the robot.

摘要： Disclosed herein is a method of controlling a robot hand similar to a hand of a human being such that the robot hand naturally and safely grasps an object. The robot hand, including fingers and a palm, is capable of naturally and safely grasping an object, by the tip of each finger performing impedance control while following the optimal path on a Cartesian coordinate system, although the robot hand cannot reach a position ideal to grasp the object due to sensor errors or shape information of the object to be grasped is not correctly recognized. Also, the robot hand is capable of stably grasping the object even when moving or manipulating the object.
