✦ Synopsis
Robots require a form of visual attention to perform a wide range of tasks effectively. Existing approaches specify in advance the image features and attention control scheme required for a given robot to perform a specific task. However, to cope with different tasks in a dynamic environment, a robot should be able to construct its own attentional mechanisms. This paper presents a method that a robot can use to generating image features by learning a visuo-motor map. The robot constructs the visuo-motor map from training data, and the map constrains both the generation of image features and the estimation of state vectors. The resulting image features and state vectors are highly task-oriented. The learned mechanism is attentional in the sense that it determines what information to select from the image to perform a task. We examine robot experiments using the proposed method for indoor navigation and scoring soccer goals.
