Abstract
A robot system includes a robot having a sensor mounted thereon and a control unit, wherein the sensor acquires sensor data within at least one field of view, wherein the control unit defines or selects a volumetric safety zone located at a position relative to the robot; wherein the control unit controls the sensor to move such that the field of view covers the safety zone; wherein the control unit controls the robot to move in a movement direction; and wherein the control unit triggers a safety response upon detection of an object or body part of a human within the safety zone.
Claims15
A robot system, comprising:
- a robot;
- a control unit;
- and
- at least one sensor;
- wherein the at least one sensor is mounted on the robot;
- wherein the at least one sensor is configured to acquire at least one sensor data within at least one field of view, wherein each sensor of the at least one sensor unit is configured to acquire sensor data within a field of view of the sensor;
- wherein the control unit is configured to define or select a volumetric safety zone located at a position relative to the robot;
- wherein the control unit is configured to control the at least one sensor to move such that the at least one field of view covers the safety zone;
- wherein the control unit is configured to control the at least one part of the robot to move in a movement direction;
- and
- wherein the control unit is configured to trigger a safety response upon detection of an object or body part of a human within the safety zone.
A method of controlling a robot, wherein at least one sensor is mounted on the robot, and wherein the method comprises:
- acquiring, by the at least one sensor, at least one sensor data within at least one field of view, wherein each sensor of the at least one sensor acquires sensor data within a field of view of the sensor;
- defining or selecting, by a control unit, a volumetric safety zone located at a position relative to the robot;
- controlling, by the control unit, the at least one sensor to move such that the at least one field of view covers the safety zone;
- controlling, by the control unit, the at least one part of the robot to move in a movement direction;
- and
- triggering, by the control unit, a safety response upon detection of an object or body part of a human within the safety zone.
A computer program element that includes computer executable instructions that, when executed by a computer, carry out a method of controlling a robot, wherein at least one sensor is mounted on the robot, and wherein the method comprises:
- instructions for acquiring, by the at least one sensor, at least one sensor data within at least one field of view, wherein each sensor of the at least one sensor acquires sensor data within a field of view of the sensor;
- instructions for defining or selecting, by a control unit, a volumetric safety zone located at a position relative to the robot;
- instructions for controlling, by the control unit, the at least one sensor to move such that the at least one field of view covers the safety zone;
- instructions for controlling, by the control unit, the at least one part of the robot to move in a movement direction;
- and
- instructions for triggering, by the control unit, a safety response upon detection of an object or body part of a human within the safety zone.
