Abstract: A first device is mounted on a robot, and signals are transmitted between the first device and at least one second device placed at a certain physical location. Based on the signals, one or more positions in a coordinate system of the robot are determined. For this purpose, the robot may move the first device so that the signals can be transmitted for different physical locations of the first device.
