Abstract: A method for recovery of a frictional brake device of an industrial device, the method including executing a recovery operation, the recovery operation including at least one movement of a second member of the industrial device relative to a first member of the industrial device, while engaging the brake device to apply braking energy to the movement; monitoring an actual value related to braking energy of the brake device during the recovery operation, the actual value being not related to speed of the movement; and stopping the recovery operation when the actual value reaches the at least one target value. An industrial device is also provided.

Abstract: A method for determining a dynamic friction torque of a frictional brake device of a joint of an industrial robot, the method including performing a disengaged brake movement of an electric motor of the joint while the brake device is disengaged; determining a disengaged brake torque value based on a torque reference of a control loop of the electric motor during the disengaged brake movement; performing an engaged brake movement of the electric motor while the brake device is engaged; determining an engaged brake torque value based on a torque reference of the control loop during the engaged brake movement; and determining the dynamic friction torque of the brake device based on a difference between the engaged brake torque value and the disengaged brake torque value. A control system and an industrial robot are also provided.

Abstract: A system and a method for controlling movements of an industrial robot during a work cycle including visiting and performing work on a plurality of workstations in a work cell. The system includes a set of predefined workstations. Each workstation includes preprogrammed robot code adapted to the workstation, an entry point defining the entrance position to the workstation, and one or more predefined paths to be followed by the robot at the workstation. A user interface is adapted to provide information about the predefined workstations and allows an operator to select one or more of the predefined workstations and to specify a desired part flow between the workstations. A scheduling unit is adapted during execution of the work cycle to schedule the execution order for the workstations based on the workstations selected from the predefined workstations and the desired part flow, and to control the movements of the robot based on the scheduled execution order and the predefined paths.

Abstract: An industrial robot including a tool flange at an end of an outer arm of the robot. A tool is secured to the tool flange. A sensor is configured to sense forces and/or torques applied to a tool secured to the tool flange. The sensor is built into the structure of the robot in the region of the tool flange.

Abstract: An industrial system including a machine for processing or producing a product. The machine includes at least one actuator providing a repetitive sequence of movements of a machine part, and a regulator controlling the movements of the actuator in response to a reference value. An industrial robot is adapted to tend the machine. The robot includes a drive unit and a robot controller adapted to generate control signals to the drive unit based on a control program including movement instructions for the robot. The robot controller is adapted to generate the reference value to the regulator based on a control program including movement instructions for the machine part. The regulator may also be an integrated part of the robot controller.
