Abstract
A method for operating at least one robot includes determining the minimum distance of the robot from an obstacle, in particular the closest obstacle to the robot, in particular excluding at least one previously known, in particular temporary, obstacle; reducing the maximum speed of the robot if this minimum distance is below a first minimum distance; and reducing this maximum speed of the robot more if the minimum distance is below a second minimum distance which is smaller than the first minimum distance.

1-10. (canceled)
A method for operating at least one robot, the robot including a manipulator arm comprising a plurality of joints and corresponding drives for actuating the joints controlled by a robot controller, the method comprising:
- determining with a computer a minimum distance between the robot and an obstacle;
- issuing a command by the robot controller to at least one drive of the robot for reducing a maximum velocity of the robot in response to the determined minimum distance falling below a first minimum distance value;
- and
- issuing a command by the robot controller to at least one drive of the robot for further reducing the maximum velocity of the robot in response to the minimum distance falling below a second minimum distance value that is less than the first minimum distance value.
A system for operating at least one robot, the system comprising:
- means for determining a minimum distance between the robot and an obstacle
- means for reducing a maximum velocity of the robot in response to the determined minimum distance falling below a first minimum distance value;
- and
- means for further reducing the maximum velocity of the robot in response to the minimum distance falling below a second minimum distance value that is less than the first minimum distance value.
A computer program product for operating at least one robot, the robot including manipulator arm and drives for moving the manipulator arm, the computer program product including program code stored on a non-transient, computer-readable storage medium, the program code, when executed by a computer, causing the computer to:
- determine a minimum distance between the robot and an obstacle;
- reduce a maximum velocity of the robot in response to the determined minimum distance falling below a first minimum distance value;
- and
- further reduce the maximum velocity of the robot in response to the minimum distance falling below a second minimum distance value that is less than the first minimum distance value.
