  • Publication number: 20220152820
    Abstract: A method of teaching in a holding force for holding an object by a gripper of a robot manipulator, the gripper having gripper jaws elastically deformable in a reversible manner, the method including: closing the gripper until the gripper jaws contact the object at contact points of the gripper jaws; externally applying a desired closing force at connection points of the gripper jaws to gripper jaw bearings such that the connection points move relative to the contact points, thereby elastically deforming the gripper jaws; actuating a gripper drive to maintain the current position of the connection points and terminating the closing force externally applied onto the connection points; and ascertaining and storing a value of a gripping force or a gripping torque, wherein the gripping force or the gripping torque is produced by elastic deformation of the gripper jaws and is exerted onto the connection points by the gripper jaws.

  • Patent number: 10357886
    Abstract: The invention relates to a joint device, comprising an electric motor, an electrically controllable blocking apparatus), various control apparatuses, and a brake system, in the case of which brake system, in various alternatives, the brake system takes maximum energy from the system by means of active closed-loop/open-loop control or by triggering a (cycled) short circuit whenever possible and only triggers the mechanical blocking as a last resort in order to protect the mechanical and electrical system itself, but nevertheless ensures that the system is securely shut down after a maximum time.
