A method and a system for synchronising angles of at least two displaceable working means (2, 2') at a predetermined point of action (4) is disclosed. The working means are, in particular, a robot-controlled tool or a robot-controlled radiation emitter and/or radiation receiver. In order to synchronise angles in a precise manner, the directions of the action (1, 1') of the working means (2, 2') are, in particular represented in a continuous manner, detected and united at a predetermined point of action (4). The angle (a) between the directions of the action (1, 1') of the working means (2, 2') is determined by, in particular, an optical angle measurement and is adjusted to a predetermined value.
