A robot comprises at least one articulate arm having members including a base, an end effector and a plurality of links, wherein each link is movably connected to two others of said members by respective joints, at least one sensor for detecting an external force acting on any one of the members, and a controller for controlling movements of the joints, so as to move the end effector along a pre-programmed path. In case of the sensor detecting an external force, the controller is adapted to adopt a first release strategy for escaping from the external force, to evaluate whether the first strategy is successful, and if not, to adopt a second release strategy.

Collaborative robot

A robotic system and method includes at least one robot actively or passively mobile between at least first and second locations, and a first safety configuration being defined at least for said first location. A first data carrier associated to the first safety configuration is located in said first location, and the robot comprises a reader adapted to read the first data carrier when the robot is in said first location.

A distance measuring system includes: at least one emitter, which emits a frequency-variable scanning signal; at least one receiver; and an analysis unit for computing a distance to an object reflecting the scanning signal on the basis of a difference between the frequencies of the emitted and the received scanning signal. The rate of change of the frequency of the scanning signal in a first operating mode of the distance measuring system has a first finite value. The rate of change of the frequency in a second operating mode has a second finite value. The analysis unit is configured to compute a first distance on the basis of a frequency difference ascertained in the first operating mode, to compute a second distance on the basis of a frequency difference ascertained in the second operating mode, and to evaluate the correspondence between first and second computed distance.

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.
