A method for estimating a wrench acting on a reference point of a robot includes the steps of: a) measuring at least one component, but not all components, of the wrench; and b) estimating non-measured components of the wrench based on a dynamical model of the robot while taking into account the measured components.

A method of determining a joint torque in a joint of an articulated industrial robot, the robot having a first arm and a second arm which are coupled to each other by the joint and which are movable relative to each other by an electric drive unit coupled to the first and second arm, includes: controlling the electric drive unit by an electronic control device; assigning a measuring device to the electric drive unit, the measuring device measuring an electric current supplied to the drive unit; determining an actual value of the torque which is applied to the second arm from the measured electric current; and comparing, using the electronic control device, the determined actual torque value with a predetermined desired torque value for the joint.

A safety control system has a control unit with safety control logic, a safety sensor arrangement, a machine arrangement operable in different operation modes, each operation mode having a different productivity, the control unit receiving and evaluating input from the safety sensor arrangement, and, in reaction to evaluation result(s), activating an operation mode determined by the safety control logic, the safety sensor arrangement having at least two functionally redundant subsystems, control unit input including information indicating availability of the functionally redundant subsystems, the control logic being configured to activate normal operation mode with normal productivity if input indicates availability of all subsystems, activate fail-stop operation mode with zero productivity if input indicates unavailability of all subsystems, activate fail-operate operation mode with productivity less than normal but above zero if input indicates at least temporary unavailability of at least one and availability of at least another one of the subsystems.

A system for testing a distributed control system of an industrial plant is provided. The distributed control system includes at least two industrial control devices and at least one data communication device. The system includes at least one engineering computer that includes an engineering data storage unit for storing engineering data of at least one part of the distributed control system, and at least one human machine interface for manipulating the engineering data. The system also includes at least one remote data processing server connected to the at least one engineering computer via a remote data connection and including an emulating virtual machine on which a soft emulator is installed for emulating one of the at least two industrial control devices and the at least one data communication device.

A robot system, and method for controlling it, for collaborative robot applications has a movable robot arm and a controller, wherein the controller is provided to control the movement of the distal end of the robot arm along a movement path according to at least a sequence of coordinate data and respective commands of a robot program and wherein the controller is provided to determine exact movement speed and course of the movement path between consecutive coordinates according to a set of parameters. At least two alternatively selectable sets of parameters are provided which both are related to a respective individual comfort level of a respective collaborative human worker.
