In a method for controlling an orienting/positioning system, the orienting system comprises at least one sensor means, an external motion detection device for detecting an externally-caused motion in the environment of the sensor means and actuator means for controlling an orienting and/or positioning action of the sensor means. The method comprises the steps of: (a) Evaluating pre-action output information of said sensor means in order to detect the position of a pattern in the input space of the sensor means; (b) Deciding on a targeted post-action position of said pattern in the input space of said sensor means; (c) Defining a command for the actuator means by mapping any deviation of the pre-action position and the targeted post-action position in the input space coordinates of the sensor-means to actuator control coordinates using a predefined mapping function; (d) Orienting/Positioning the sensor means by the actuator means according to the defined command in order to carry out an orienting/positioning action; (e) Detecting the real post-action position of the patterns in the input space of said sensor means; (f) Detecting external motion of the pattern; and (g) Adapting the mapping function used in step (c), wherein steps (a) to (g) are repeated using the respectively adapted mapping function. An output signal from the external-motion detection device can be used to control the adaptation step (g).

The invention relates to the control of an orienting/positioning system comprising comprising at least a sensor and an actuator for controlling an orienting and/or positioning action adapted to change an input space of the sensor. A first step evaluates pre-action output information of the sensor in order to detect a pre-action position of a manipulating device in the input space of the sensor. A second step decides on a targeted post-action position of the manipulating device in the input space of the sensor. A third step defines a command for the actuator by mapping any deviation of the pre-action position and the targeted post-action position in the input space of the sensor to actuator control coordinates using a predefined mapping function. A fourth step orients/positions the manipulating device according to the defined command in order to carry out the orienting/positioning action. A fifth step detects a real post-action position of the manipulating device in the input space of the sensor. A sixth step adapts the mapping function used in step three based on any difference of the real post-action position and the targeted post-action position of the manipulating device in the input space of the sensor in order to carry out an incremental adaptive learning of the mapping function. According to one embodiment of the present invention, steps S1 to S6 are cyclically repeated at least once using the respectively adapted mapping function.

A robot controller including a multitude of simultaneously functioning robot controller units. Each robot controller unit is adapted to receive an input signal, receive top-down information, execute an internal process or dynamics, store at least one representation, send top-down information, issue motor commands wherein each motor command has a priority. The robot controller selects one or several motor commands issued by one or several units based on their priority. Each robot controller unit may read representations stored in other robot controller units.

A method for estimating the location of a sound source. First, a first microphone and a second microphone are moved relative to the sound source. Then the Intra-aural Time Difference (ITD) between the two microphones is measured. The moving and the measuring are repeated until the Intra-aural Time Difference (ITD) is smaller than a predefined threshold.
